On July nineteenth, during dinner,
0:03
announcement was made of the departure of Sister
0:05
Rogers after an illness of eight days.
0:08
This was the beginning of a great time of sorrow
0:11
for Bethabara and for me. A
0:13
strange kind of fever had broken out
0:15
amongst us, and most of those living in
0:17
Bethabara had it in more or less
0:19
a serious form. My doctor
0:21
was much worried, for the usual treatment for fever
0:24
gave little relief. Of those
0:26
who left us, Sister Rogers was the first,
0:28
but not the last. Next
0:31
came Catherine's Sidle, and it seemed
0:33
almost impossible that only a few
0:35
short weeks before she had traveled south
0:37
with us. Her husband missed her
0:39
sadly, and it was only a few days
0:41
later that he returned from a visit to Bethania,
0:44
oppressed by the feeling of utter weariness,
0:47
which we were learning to recognize as the first
0:49
symptom of the disease. He did
0:51
not seem very ill at first, but when
0:53
hope was expressed for his recovery, he shook
0:55
his head.
0:56
And so it was.
0:58
And then my Martin, perhaps because
1:00
of his unremitting efforts for others, he
1:03
was seriously ill from the first he
1:05
saw what was coming. His
1:07
pain was intense, as it always was
1:09
in the earlier stages of the fever. His
1:12
request was stay by me and
1:14
hold my hand, hold it tight. And
1:16
when the fever mounted, when the terrible
1:19
red splotches broke out on his body, when
1:21
delirium came, he still felt
1:23
my presence and was quieted as I
1:25
held his hand in mine spoke gently
1:27
to him or saying some of our best loved
1:30
hymns. Then he became unconscious
1:32
of pain or weariness, but we were still
1:34
hand in hand when the call came that took
1:37
him back to the eternal home. Others
1:39
were laid to rest beside him, but I was
1:41
stunned and rebellious, and nothing seemed
1:43
to matter much. The fever that
1:45
took Martin from me persisted until late
1:48
in the fall, though with decreasing violence,
1:50
and we heard that it was prevalent in many parts of
1:52
North Carolina and Virginia.
2:37
WHOA, Yeah,
2:40
that's a sad story. It's
2:43
really sad.
2:44
So that is from
2:47
an account from seventeen fifty nine,
2:50
and I found it in a paper referenced
2:52
in a book that I read. The paper
2:54
is titled a seventeen fifty nine spotted
2:57
fever epidemic in North Carolina.
3:00
Before we go any further, it's
3:03
debated this, Like the whole purpose
3:05
of this paper is to, you
3:08
know, say, this might be an instance of
3:11
spotted fever or Rocky Mountain spotted fever.
3:14
It's not certainty, but I.
3:16
Liked the account so much that
3:18
I wanted to read it.
3:20
It was a really good account. Right,
3:22
it's heartbreaking by
3:24
everything that you that was
3:27
in that account. It certainly could be
3:29
Rocky Mountain spotted fever.
3:31
There are a few things that are like, as we'll
3:34
talk about that seem a little
3:36
bit off to me. I mean the fact that, like, was
3:38
it contagious. It seemed to be all
3:40
at once. It's not contagious anyway.
3:43
So yeah, okay, maybe
3:45
we should maybe we should
3:48
pump the brakes. Yeah, because
3:51
Aaron, what are we this
3:54
is this podcast will kill
3:56
you.
3:57
I'm Aaron Welsh and I'm Aaron Olman Updike.
4:00
Welcome. Wow, we did
4:02
that all weird and backwards. Yeah, that
4:04
was backwards, but we're professionals.
4:07
Oh totally, We've done this before. We've
4:09
done this before. Fifty oh
4:11
my lost count already. This
4:13
is fifty five
4:16
or six? No, yeah,
4:18
I thought it was fifty two. Antibiotics
4:22
was last week?
4:26
Oh gosh, Well, this
4:28
week we are covering Rocky
4:31
Mountain spotted fever or Rickettsia
4:34
RICKETTSI. I yes, spotted
4:36
fever group Rickhetsia.
4:40
I am very excited about
4:42
this episode, Aarin.
4:44
I didn't start out that way, but
4:48
I've come around and now I'm
4:50
thrilled.
4:51
I have known that this was going
4:53
to be a great episode since we
4:55
literally decided to make a podcast.
4:57
Okay, oh okay,
5:00
and I guess the two reasons why?
5:02
Uh okay, yeah, please guess them.
5:04
Are there two reasons why? First to allow, but
5:07
please guess them? Okay.
5:10
Number one is because of the Quarantini
5:12
name. So what's our quarantini name? Aaron,
5:16
that's segue. Oh
5:18
my god, we're being so obnoxious. Okay.
5:21
Our quarantini is cold
5:25
is the Rocky Mountain spotted Fever.
5:28
That's the most clever name that we could come up with. It's
5:30
so good. We came up with that quarantiny
5:34
literally the same moment that we came
5:36
up with a podcast idea.
5:38
Yeah, it was on our list
5:40
that very first day original at
5:43
the picnic of like what
5:45
are we or at the barbecue?
5:47
Yep? Exactly what are the quarantini names? So
5:50
in this quarantine, of course you
5:52
have to have Core's light not sponsored.
5:57
Because the logo is called as the Rockies.
6:00
Just in case anyone has forgotten.
6:02
And well, basically we're making a shandy out
6:04
of it. Okay, yeah, super simple,
6:07
delicious. We'll post a full
6:10
recipe for that quarantine as well as
6:12
a non alcoholic plus see Burta
6:14
on our website. This podcast will kill you dot com
6:16
and all of our social media channels, Yes
6:19
we will. So, Aaron, what's the second reason
6:21
that you knew I was going to be excited
6:23
about this episode because
6:26
we.
6:26
Get to tell the story of Oh
6:28
Brett possibly
6:31
having Rocky Mountain spotted fever.
6:35
Genuinely forgot about that. I
6:37
mean I didn't forget about that. I just I forgot
6:39
that aspect of it.
6:41
I can't rememberative moment of
6:43
our friendship.
6:44
Oh, it absolutely
6:46
was. I will never forget the
6:49
moment. Okay, I
6:51
just meant I forgot that we're going to get the opportunity
6:53
to talk about it.
6:54
Oh right, right, right, Okay,
6:56
So why did you think it was going to be such
6:58
a great episode From the.
6:59
Very Oh mostly
7:01
the quarantine name. Oh yeah,
7:04
yeah, yeah,
7:06
excellent. But as
7:08
I was researching for this episode, I
7:12
you know, I also was having a
7:14
really busy week and I was like, oh gosh,
7:16
I have to do research. But then the very
7:18
first paper that
7:21
I came across to do research for
7:23
this episode, the first line
7:25
of the biology section, I was
7:27
like, Oh, this is this is gonna be a
7:29
good one. Aaron. I had to google two
7:32
words in the first sentence. What
7:35
were they? Fastidious
7:37
and pleomorphic? Ooh
7:40
yeah, it's a good sentence. I'll read it to you later.
7:44
Also, I have to say that the
7:46
book that I read, the very first
7:49
line, like of the chapter,
7:52
so you know how like chapters start with like a quote
7:54
from whatever.
7:55
M hm. It literally it
7:57
made me go, oh, this is gonna be
7:59
good, and I put it in my notes. Look
8:02
at us both we are the same person.
8:08
Oh man, Oh my gosh, that's
8:10
really funny.
8:11
So do we get to just like, you
8:13
know, do the episode now or do we have that
8:16
business.
8:18
We've got new merch
8:20
coming out soon. Yeah, keep
8:22
an eye out for that.
8:24
It's very literally the most
8:26
exciting thing.
8:27
We love it. Yeah, love love
8:29
is not a strong enough word. What's
8:32
a stronger emotion, really
8:37
love? Okay,
8:43
I don't think we have any other business to attend
8:45
to, Aaron, So let's let's
8:48
take a short break and then get into the biology
8:50
of this.
8:51
Oh my gosh, let's do it.
9:26
Okay, So here it goes quote ricketsia
9:30
ricketsi I is a fastidious
9:33
small pleomorphic gram
9:35
negative coxo bacillis. Okay,
9:39
okay, So I
9:42
feel okay that description.
9:45
It's why people don't like reading scientific
9:47
papers, oh for sure. And
9:50
I the reason that
9:52
it made me excited for this episode
9:55
is because I was like, I really like that.
9:58
This is how if you read that, you'd be
10:00
like, oh snooze, I don't want
10:02
to learn anymore. So now I'm going to take
10:04
that and make it a lot more exciting and
10:07
tell you why you should be excited about rikkeetsia
10:09
ricketsia I. Okay, oh
10:11
yes, please, Okay. So here's
10:14
what that boring sentience
10:17
means. We're talking today
10:19
about a very very
10:22
tiny, like so tiny that it
10:24
lives inside of our
10:27
cells, bacterium
10:32
that is very difficult
10:34
to grow in medium. And the reason it's
10:36
difficult to grow is because it lives inside
10:38
of cells. Is that the fastidious
10:40
part. That's what festidious means.
10:42
Yep.
10:42
Okay, when you're talking about
10:45
fastidious organisms, okay uh.
10:48
And the pleomorphic part means that not every
10:51
single coxobacillas, not every single
10:53
cell looks exactly like every
10:55
other. So they kind of when you look at
10:57
them stained inside of another
10:59
animal's cell, they look like a bunch
11:01
of little, little and bigger
11:04
dots, if that makes sense. Okay,
11:06
why that's a really good question that
11:08
I don't know, because they divide the same
11:10
way that anything else divides, right like
11:12
just by sciently. That's
11:15
fascinating, all
11:17
right. So let's get into the disease
11:20
that Ricketsia ricketsiai
11:23
causes Rocky Mountain spotted fever. So
11:26
this is a tickborn disease. OKAYO,
11:31
we get excited about these. So
11:34
humans get infected. Humans are essentially
11:37
dead end hosts, okay,
11:40
So we're not part of the normal life
11:43
cycle necessarily of this pathogen.
11:46
But humans get infected when we
11:48
are bitten by an infected tick.
11:51
Specifically, in a number
11:54
of different species, but most commonly
11:57
in most of the US, it's derma center
11:59
very abolises. That's the dog
12:01
tick, the American dog tick. But
12:04
there's also the Rocky Mountain wood
12:06
tick Derma center andersnii.
12:10
The those live in the Rocky Mountains in
12:12
Canada, the brown dog
12:14
tick rifacephalous
12:17
sanguinosis noeus
12:21
Rifocephalus sanguineous in Mexico,
12:24
and of course aarin Ambloma
12:27
cayanens or Amblioma
12:29
mixta. I was waiting for you to go
12:32
correct, correct, correct me as.
12:34
I got corrected at an academic conference.
12:37
Yes, it is now amblomicayan
12:40
and say species complex?
12:42
Okay, great, and
12:44
that's in Is that throughout Central America?
12:47
That species complex? Yes?
12:49
Central? Yeah, Central and South America?
12:51
All right, So now we also
12:54
know where this disease is found, right, This
12:56
is a disease of the New World essentially,
12:58
so North America, Central America and then
13:00
down into South America. Okay.
13:04
And like many other tickborn diseases,
13:07
in order to get infected, the tick does have
13:09
to be attached for a relatively long
13:12
period of time, usually a
13:14
minimum of four to six hours, but sometimes
13:16
up to twenty four hours. And
13:19
the reason that the tick has to be
13:21
attached for a long period of time
13:23
is because although these bacteria
13:26
are already in the salivary glands
13:28
of the tick. When
13:31
they're in the tick, I get I'm getting
13:33
excited. When
13:35
they're in the tick, they're basically
13:37
not in a virulent state,
13:41
right, So then they have to bite a
13:43
host and then something happens
13:45
within the salivary glands of the tick
13:48
to reactivate these
13:51
bacteria and make them
13:53
virulent, make them able to actually
13:55
infect our cells.
13:59
It's so.
14:02
Amazing, and when weird don't
14:05
know how it happens, and
14:07
it also like, oh my gosh, yeah,
14:09
yeah, you're right. This is a thrilling, a
14:12
thrilling disease.
14:12
Absolutely thrilling. Okay that is
14:15
I didn't know that either before researching
14:17
this, and I think that's just super fascinating.
14:21
Okay, So then you have activation,
14:25
it gets somehow becomes
14:27
virulent again, and then it will exit
14:29
the salivary glands and then enter underneath
14:33
our skin. Okay. So then,
14:35
because we know that this is a life cycle, right, how
14:38
does the tick then get infected? How do we end
14:40
up with infected ticks? As it turns out,
14:43
there's two ways that a tick can
14:45
become infected. One
14:49
one is the way that we know
14:51
of ticks getting infected from past tickborn
14:54
disease episodes, and that is that a tick
14:57
takes a bite of an infected host
15:00
and then in that blood meal they
15:02
suck up some bacteria,
15:04
okay, and then those bacteria
15:07
go on to replicate, and like
15:09
many tick born diseases, once
15:12
a tick is infected, they
15:14
remain infected for their entire
15:16
life. So even if they get infected
15:18
as a larvae, then when they
15:21
transition to a nymph, they remain infected.
15:24
When they transition to an adult, they remain
15:26
infected. But here's where
15:28
it gets interesting. I
15:31
know where you're going. Infected
15:36
female ticks transmit
15:40
transoverially and
15:42
lay infected eggs,
15:46
so you can have larval
15:48
tick bombs that burst out
15:50
already full of Ricketsia just
15:53
waiting to infect their first blood
15:55
meal host. Let's put an
15:57
asterisk on this. I'm great. Well,
16:01
I actually have a question for you
16:03
about this, okay, because
16:05
my understanding from what I read, and you
16:08
are much more of an expert if you guys
16:10
didn't know listeners. By the way, Aaron
16:12
literally did her PhD research on
16:15
Ricketsias in Central America.
16:18
So on on pathogens
16:20
in tics in Central America, which happens
16:23
to.
16:23
Be a lot of Rikkeetzias. Did you
16:25
hear her trying to ask risk her way out of that.
16:28
Well, I'm not an expert, okay,
16:33
So my question is my understanding is
16:35
that for humans
16:37
it's really only adult tics
16:39
that go on to infect humans. Is
16:42
that just behavioral? Is that just because
16:44
these ticks species don't tend to bite us
16:46
unless they're adults, or is that something
16:49
to do with infectious dose? What
16:51
is why is that? I
16:53
don't I mean, honestly, I don't know. Possibly
16:57
behavioral. I mean, so.
17:00
Different ticks species will have different
17:02
host preferences overall, So
17:05
like this tick species might like you
17:07
know, deer and mammals
17:11
more, and this tick species might like reptiles
17:13
more. But even within a tick species,
17:15
you see a lot of differences in terms of like
17:18
what they like to feed on at different stages.
17:21
And so there's a trend.
17:23
It's not one hundred percent, but there
17:25
is a trend where as
17:28
you go to the older life
17:30
stages, so like from larva to adult,
17:33
the host range narrows. And part
17:35
of that is like a mate seeking phenomenon,
17:37
because if you're trying to find a mate,
17:40
you want to be like, all right, I
17:42
want to get on this horse because I know
17:44
that other you know, ticks,
17:47
adult ticcks of my species are going to be on this horse,
17:49
but like you might not be like, oh or
17:51
maybe that squirrel or maybe that
17:53
monkey or maybe that sloth. Like
17:56
you're going to be focused in, right
17:58
because anyway, So it might
18:00
be behavioral as far as the
18:02
bacterial load overall across the
18:04
life stages, that might be a factor. But
18:07
another factor might be that
18:09
as you're in, if you're an adult tick, you've
18:12
taken two blood meals, and so just
18:14
the chance that you have acquired the
18:17
pathogen is greater than if
18:19
you have taken just one blood
18:21
meal.
18:22
It's an imful tick, right, that makes sense.
18:24
Yeah, But the asterisk that
18:26
I want to add to the trans of aerial
18:29
transmission is that it's
18:32
fairly rare, oh for
18:34
Ricketzia ricketsii, Like it doesn't happen
18:36
all that often. And actually the
18:39
Racketzi ricketsii I negatively
18:41
affects the reproductive output of the
18:43
tick.
18:44
The female six. Yeah,
18:46
so that's I mean good news in a way.
18:48
So if you look at horizontal
18:50
transmission, so getting it from an infected
18:53
animal versus
18:55
trans of aerial transmission or vertical transmission
18:57
getting it from mom, it's much less
18:59
like to get.
19:00
It from mom.
19:02
And then the third way that might be possible
19:05
is co feeding.
19:07
Oh does cofeeding
19:09
mean the same thing for ticks as it does for kissing
19:11
bugs.
19:12
Probably they're like two bugs feeding close
19:14
to one another and then they oh
19:17
what does it mean for.
19:18
Kissing Sometimes the adult
19:20
kissing bugs will come back to the nest
19:22
and then the nymphs will feed on
19:25
the adult like from their
19:28
blood meal. Beautiful
19:30
and horrifying. Yeah it is.
19:33
That's that's my esthetic, literal
19:37
lifeblood co feeding.
19:38
So then if you have say an infected adult
19:41
feeding very close by to another
19:44
uninfected nymph, then
19:47
they could that's fascinating.
19:49
Oh yeah, that happens with
19:52
tick born encephalitis virus as well.
19:54
I think occasionally you get you do get
19:56
co feeding events, and this is really important when
19:58
you have cocurrent
20:02
stages existing or
20:04
emerging. So if you have larvae that are emerging
20:06
at the same time as a.
20:07
Nymphs, yeah, then yeah,
20:10
very cool. Well
20:12
that was very fascinating. Okay, so
20:15
now we understand fully the
20:17
transmission dynamics
20:20
of this bacterium. So let's
20:22
talk about what happens if you
20:24
get infected. Okay, what
20:26
are the symptoms. It starts
20:29
with aaron wait for it,
20:32
with a fever. Oh
20:37
okay. So in general,
20:39
the incubation period after you get
20:41
infected is about seven days
20:44
on average, it can range from about two
20:46
to fourteen, and the first symptom
20:48
is often a rather sudden
20:50
onset of fever, pretty
20:53
substantial malaise and body
20:56
aches, and very commonly
20:58
a headache, which very often people
21:00
will describe as the quote worst
21:02
headache they've ever had. Is what one
21:04
paper said. Interesting,
21:07
I will say in med school, we don't learn
21:10
Rocky Mountain spotted fever as the worst
21:12
headache you've ever had. You learn that for a
21:14
brain bleed. But that's okay.
21:18
The point is it's a very severe headache. It's
21:20
not just like I feel a little dehydrated
21:22
headache. It's like a bad headache. Okay,
21:25
okay. You can have a
21:27
lot of other pretty non specific
21:30
symptoms as well, things like anorexia
21:32
because your stomach doesn't feel good, anarexia
21:35
meaning you just don't want to eat, not like
21:37
an eating disorder, nausea,
21:40
vomiting, abdominal pain is fairly
21:42
common. So, especially
21:44
early on in the course of this disease,
21:47
it's very potentially
21:49
easy to mistake it for a kind of
21:52
viral syndrome. Okay, you
21:54
feel crappy, but it's very non
21:57
specific. And then comes
21:59
the third of what's
22:01
often called the classic clinical
22:03
triad of rocky mountain
22:06
spotted fever. There's actually
22:08
two different triads, which I think is silly
22:10
depending on what paper you read. Okay,
22:13
within two weeks of a tick bite,
22:17
almost always, in like eighty
22:19
to ninety percent of cases, you
22:21
see this third symptom,
22:24
and that is the
22:27
spots of rocky mountain spotted
22:30
fever. There we go. It's
22:32
a rash. This rash
22:34
starts out as small what are
22:36
called macules, which just means flat
22:39
red spots, little ones,
22:41
maybe like less
22:44
than the size of your pinky nail.
22:48
And these tend to start on your wrists
22:51
and your ankles. They're
22:53
a blanching rash. It doesn't itch,
22:55
usually it doesn't hurt. So
22:58
if you press on them, then the co would drain
23:00
from them. Okay, oh that's what a
23:02
blanching rash. Wow, yeah,
23:05
cool new word. New word. Then
23:07
this rash, which starts on your ankles
23:09
will begin to spread. It will spread
23:11
up approximately like up your arms
23:14
and up your legs to your trunk. But
23:17
It also spreads down down
23:19
to your palms and your souls,
23:22
which you may remember from our episode
23:24
on syphilis is a very uncommon
23:27
place to have a rash.
23:30
The palms of your hands and the soles
23:32
of your feet really don't get
23:34
rashes except in a
23:37
few infectious diseases.
23:39
Okay, it was syphilis, syphilis, hand
23:43
foot mouth Cocksacki virus,
23:45
and Rocky Mountain spotted fever.
23:47
Rocky Mountain spotted fever. Is that it?
23:49
That's it? There are you know? You could
23:51
get fungal infections on your palms
23:53
or souls. You could get contact
23:56
dermatitis and things, but in terms of infectious
23:58
diseases, those are the three big ones, and
24:01
it would be all like both hands,
24:03
both feet, both hands, both feet exactly. Yeah.
24:06
But it's not itchy, not itchy usually,
24:09
and not painful. Not painful. Well
24:12
that's that's nice. Yeah, well not
24:14
really. I
24:17
spoke too soon. Spoke too soon. Okay,
24:20
So this rash is now spreading. By
24:22
the end of about a week of having this
24:24
rash, the rash becomes raised, so
24:27
it's now what we call maculo popular.
24:29
So it has red flat spots
24:32
with little dots raised
24:34
bumps in the middle. And
24:36
then in the center of these lesions you can
24:39
sometimes get patikia, which are little
24:41
pinpoint purple spots that usually
24:43
are a sign that you're having some kind of issues
24:46
with your blood clotting. And
24:49
so that is kind of the
24:51
general course of disease.
24:54
It doesn't sound that bad,
24:57
right, Well, that
25:01
was a leading question. I
25:03
mean it doesn't though, Right, It's like headache, fever,
25:05
you're feeling crappy, you get a rash.
25:08
But then, as it turns out, this
25:11
disease is about okay
25:13
without treatment. And before we had treatment
25:16
for it, it was on average
25:18
about twenty five percent fatal. But
25:21
that fatality rate ranged a
25:23
lot from about twenty percent
25:25
to maybe up to eighty five percent
25:28
depending on where geographically
25:30
you got infected. Yep,
25:33
so this is a highly fatal
25:36
illness.
25:37
Right if your average,
25:40
if your lower level is still
25:42
over what did you.
25:43
Say, twenty five percent?
25:45
Yeah, If the average is twenty five percent,
25:49
that's I mean, think about
25:51
the other ones that we've had that have been twenty five
25:53
percent, right, it's not that many exactly.
25:55
That that's a huge case fatality rate.
25:58
Yeah, So the
26:01
question is what are you dying from?
26:03
Right, You've got a rash. How
26:05
is this killing you?
26:07
Well, I feel like the petitia or
26:09
whatever, the blood clotting issue, that
26:11
might be an indication.
26:13
Yeah, so that's one sign. So let's talk
26:15
about kind of the actual pathophysiology
26:17
of how this makes you sick. What's going on when
26:20
you have this rash? Okay, So
26:23
this is a tickborn disease. So, like
26:25
many other tickborn diseases, when
26:28
that tick spits the bacteria underneath
26:31
your skin, those bacteria travel
26:34
through your lymphatic system to end
26:37
up in their host cells.
26:40
And even though this is a bacterium,
26:43
it acts a little bit more like a virus
26:45
in that it has to invade our
26:48
cells. It's an intracellular bacteria
26:51
in order to replicate. It does not have
26:53
the machinery to replicate outside
26:56
of a host cell, much
26:58
like a virus.
27:00
So isn't there some sort of like
27:02
isn't it thought that ricketsia are
27:06
might be closely related to mitochondria?
27:10
Yes? I believe so they think that mitochondria
27:12
came from something, whether a precursor
27:15
to a ricketsia or something similar.
27:17
Because they're like, yep, yes,
27:19
I just think that's so cool. Oh, it's so cool.
27:22
It's so cool. Their genomes are tiny. Okay,
27:25
So in the case of ricketsia
27:27
ricketsia, the cells
27:29
that they invade, the cells
27:31
that they replicate in are
27:34
our vascular endothelium.
27:37
So those are the cells that line
27:40
our blood vessels. Okay, the
27:42
inside lining of our blood vessels.
27:44
Okay, you see where we're going with this, I
27:46
mean, yeah, yeah. Unfortunately, So
27:49
what happens when they enter our cells and
27:51
start to replicate, They they
27:54
do a very good job replicating. They replicate
27:56
by fission. They also have these
27:58
ways of mood from
28:00
cell to cell to sell without
28:03
necessarily damaging our cells
28:05
directly as they move from cell to
28:07
cell, so they can kind of just
28:09
spread along your blood vessels,
28:12
just jumping from cell to sell to sell. And
28:15
because they're in your blood vessels,
28:18
they are literally anywhere
28:20
and everywhere in your body because everywhere
28:23
needs blood, right. And
28:26
then they start to cause direct
28:28
damage to the cells that they infect,
28:31
and they do this in a few different ways. One
28:33
is free radical induced injury, which
28:36
I feel like we're experts on now
28:38
after our radiation episode, Okay,
28:44
and then they also release a number of different
28:46
enzymes that cause damage to these cells.
28:49
So if you are damaging
28:51
the cells that line your blood vessels.
28:54
What do you think is going to happen to the
28:57
fluid that is supposed to be in your blood
28:59
vessel.
29:01
Well, it's gonna create a little leaky
29:03
pipeline, A.
29:03
Little leaky pipeline erin exactly.
29:06
Okay, So this cell damage
29:09
causes exactly that, not frank
29:12
hemorrhage. Okay, they're not like, it's
29:14
not gross enough damage that you're going to be
29:16
bleeding out necessarily.
29:18
Who's frank hemorrhage?
29:25
I'm sorry?
29:31
Uh oh did.
29:33
You like that? I really did so,
29:37
not actual hemorrhage. But
29:39
this damage does cause increase
29:42
in the permeability of that
29:44
membrane essentially, so that means you're
29:46
going to get fluid plasma leaking
29:48
out. This is going to also
29:51
cause you to lose protein because as
29:53
you damage that membrane, proteins
29:56
are usually kept in your blood
29:58
vessel in part by a charge
30:00
differences. So you mess up that membrane,
30:03
you mess up those charges, so
30:05
then protein can leak out more easily,
30:07
which then just draws more liquid
30:09
out with it.
30:10
Okay, so it's like this cascading
30:12
horrible exactly, positive feedback.
30:15
Loop exactly, And let's talk about positive
30:17
feedback loops. Okay, Because,
30:20
like we talked about in the radiation episode,
30:23
when you have this free radical damage
30:26
that happens to these cells, our
30:28
body mounts a response to that,
30:30
right, and that's an inflammatory response. And
30:33
in responding to that, part
30:36
of what our body does to try and
30:38
fight off the inflammation
30:41
and damage that's caused by things like
30:43
free radicals and these enzymes
30:46
is that they will vasodilate our blood
30:48
vessels in order to get more white
30:50
blood cells to the areas that they need
30:52
to be to try and fix this damage. That
30:55
vasodilation means you have more flow,
30:57
which means you have more vascular
31:01
permeability, which means
31:03
you have more leakage. So
31:06
this will eventually lead to edema,
31:09
so swelling outside liquid
31:11
outside of our blood vessels, and
31:13
eventually hypovolemia where you don't
31:15
have enough volume in your blood vessels.
31:19
On top of that, if it happens
31:21
to be important organs like your brain
31:23
or your lungs that get involved in
31:25
this, this is called a vasculitis
31:28
where you have inflammation of
31:30
your blood vessels. If
31:32
it's somewhere like your brain or your lungs,
31:35
you don't have a lot of good lymphatic drainage
31:37
to drain that fluid away, so
31:40
you have pressure that builds up because
31:42
of that in that interstitial space.
31:45
So what's interesting
31:47
about this is that none
31:50
of the papers that I read really
31:53
clearly outlined what the
31:55
exact cause of death tends
31:58
to be in Rock Mountain
32:00
spotted fever. But
32:02
it is essentially organ failure.
32:05
What organ it is that ends up failing
32:07
kind of just depends on what organ happens
32:10
to be the most affected. A
32:12
very large proportion of people have hippatomegaly
32:16
on necropsy or on autopsy after
32:19
they've passed, so your
32:21
liver is very commonly involved,
32:23
at least in fatal cases. Many
32:25
people also have renal failure, so
32:27
kidneys might fail. Your
32:30
lungs can certainly be involved, so you
32:32
could die maybe just from not being able to
32:34
breathe from respiratory failure because
32:36
of all the fluid around your lungs. But
32:39
there's not like a one single
32:42
thing that tends
32:44
to be the ultimate cause of death necessarily.
32:47
But pathophysiologically we know that
32:49
it's this diffuse vascular damage
32:51
that leads to hypovolemia,
32:54
so not enough volume and eventual
32:56
shock. So yeah,
33:00
terrible, really terrible.
33:05
Another thing that I did want to point out that
33:07
I think is really really important about this
33:09
disease is that the mortality rates
33:12
still today, It's non trivial.
33:15
It usually hovers around five percent
33:17
even with treatment. And there is very
33:19
good treatment for this. Doxycycling a
33:22
few days worth clears infection,
33:25
but delays in diagnosis
33:28
are strongly associated with
33:30
poor outcomes. So not
33:32
getting to a doctor fast enough, or
33:35
a doctor failing to make the correct diagnosis
33:38
or get the treatment initiated quickly,
33:41
is very strongly associated with a
33:43
vastly increased risk of death, and
33:46
especially in the US, this disproportionately
33:49
affects black individuals.
33:53
And you know, there
33:55
was a limited amount of discussion
33:57
in the papers that I read as to why it's
34:00
exactly that is, whether it's you
34:02
know, people not seeking
34:04
care and things like that. But
34:07
my guess, and some of the papers
34:09
also said this, is that we
34:11
are really bad at diagnosing
34:14
rashes on black skin. It's
34:17
yeah, it's a huge issue.
34:20
When you google pictures of this, I
34:22
haven't seen a single picture of Rocky Mountain
34:24
spotted fever on a black skinned person.
34:27
Yeah, it's yeah.
34:28
I came across that as well in the
34:30
research and how it's like historically it's been
34:32
it's been like that as well.
34:33
Yeah, and I mean it's not just for this, but this is a
34:36
very fatal disease that's also very treatable
34:38
if you diagnose it properly. And
34:41
so the thing is, we don't have good
34:43
tests, like laboratory tests to diagnose
34:46
this. It's a clinical diagnosis, which
34:48
means you make that diagnosis
34:50
based on history and physical
34:52
findings, including a rash.
34:55
So if we don't know what a rash is supposed to
34:57
look like, because no one's taking
34:59
pictures of it, no one's you know, it's not in
35:01
our textbooks, et cetera, then
35:03
people are dying unnecessarily, which is a
35:05
huge, huge failure of
35:08
the medical system. So
35:11
absolutely, So, yeah,
35:14
that's the biology of Rocky Mountain spotted
35:17
fever. Well,
35:21
it's a terrible disease.
35:22
And that is that's a point that I saw made
35:24
in a lot of different papers in terms of like how
35:28
important this disease is and how
35:30
overlooked it tends to be despite
35:33
the fact that things like landscape
35:35
change and climate change are going to
35:38
greatly shift our exposure,
35:40
our risk, you know.
35:42
Yeah, and I mean it's it's the kind of case where
35:44
it directly results in like people
35:47
dying, you know, but
35:50
it is, it is. It's a difficult thing because
35:52
it is so rare. And I think
35:54
that you know, we'll talk later
35:56
about where you see this geographically,
35:59
but I think a lot of people well maybe don't know or
36:01
don't know to think of it, you
36:04
know, when they're when they're kind of listing their
36:07
their differentials in their head, it could easily
36:09
look like a viral illness. It's like, oh, you've
36:11
got a fever and a headache and you're feeling crappy.
36:14
You know.
36:15
Well, and in the history section,
36:18
I don't talk much about like the name
36:20
itself, but if you look at
36:22
so many different ricketzial diseases they
36:25
tend to have, particularly the arthropod born
36:27
ones, they tend to have location
36:31
specific name. Yeah, And so in
36:33
one place it's Rocky Mountain spotted
36:35
fever, in another place it's something
36:37
else. And so you have like all over the world, you
36:39
know, different species of pathogetic Rikeetsia
36:43
called by different names, and that
36:45
has created a lot of confusion, particularly
36:48
with Rocky Mountain spotted fever. Since we're talking
36:50
about it, like, yes, it occurs
36:53
in the Rockies in the Western States, but
36:56
the eastern seaboard is like bam,
36:59
South America bam, right Central
37:01
America bam.
37:02
Like it's there too.
37:05
And so there was a huge push at one
37:07
point to just call it spotted
37:09
fever or spotted fever group
37:11
of KEETSI but that never really caught on.
37:13
So RMSF is what it
37:15
is. So
37:18
well, tell me more, Aerin about this history.
37:20
How did we get here? Where
37:22
did this thing come from? Okay,
37:25
I cannot wait.
37:26
We will take a quick break first, Aaron,
37:51
you started off biology with a
37:53
quote, and I laughed because
37:57
I'm starting off history with a quote.
38:00
I love it.
38:02
You started off with the quote from the first
38:04
paper you read, and I'm
38:06
starting off with that quote from the book
38:09
from the very beginning. Okay,
38:12
here we go, the
38:15
unwritten history of the investigational
38:17
work in connection with Rocky Mountain Spotted
38:19
Fever, if written would
38:21
read like a romance.
38:26
I mean you see why. I
38:28
was like, what what is this? Okay?
38:35
So yeah, I mean
38:37
why is that? Yeah? Hopefully
38:39
I'll tell you.
38:41
Hopefully I'll do a good enough job that you'll
38:43
understand what that quote means. I'm not sure that I do
38:46
anyway.
38:47
So.
38:48
I mean, and I before researching
38:51
this, I didn't know there's
38:54
quite a bit of like lore
38:57
or fame or infamy
38:59
around owned Rocky Mountain Spotted fever
39:01
research.
39:02
There was a movie.
39:03
Called green Light starring
39:05
Eryl Flynn from nineteen thirty seven, and
39:08
one of the subplots it tells the story
39:10
of the researchers involved on the
39:12
Rocky Mountain Spotted Fever project. What
39:16
Yeah, and the disease itself plays
39:18
a major role in the nineteen
39:20
forty seven movie Driftwood. I
39:22
haven't seen either of these, so I can't vouch
39:25
for their accuracy or how much romance
39:27
they have in them or whatever. But
39:30
I have now read about the history of Rocky Mountain
39:32
Spotted Fever, especially
39:34
the history of its research, and that
39:36
does contain a fair amount of drama
39:39
and romance.
39:41
To start the story, we.
39:44
Don't have to go all that far back,
39:46
actually, so the first hand account
39:48
that I read in the beginning of the episode, as I mentioned,
39:50
is from seventeen fifty nine. But
39:53
like I said, it's not one hundred percent accepted
39:55
to be Rocky Mountain Spotted Fever.
39:58
In any case, there were likely k of
40:01
our msf Rocky Mountain spotted fevers scattered
40:03
throughout the Americas for hundreds
40:05
of years at least, But the real
40:08
story begins only in the late eighteen
40:10
hundreds. We don't
40:12
have written records for anything
40:14
earlier. Yeah, So around
40:16
this time, starting in maybe the
40:18
eighteen sixties or the eighteen seventies,
40:21
a mysterious illness was seeming
40:23
to pop up in the bitter Root Valley
40:25
in Montana. So this
40:28
if you can picture Montana in
40:30
your head, go to the far
40:32
far west, kind of the southwestern
40:36
part of the state. If
40:38
you know where Missoula is, it's like the
40:40
very north end of the valley.
40:42
I don't know where that is, but I can
40:45
picture Montana, So Okay.
40:48
So this valley, the Bitterroot Valley,
40:50
runs about ninety five miles long,
40:52
and it's sandwiched in between the bitter Root
40:54
Mountains and the Sapphire Range, with the
40:57
bitter Root River winding its way through
40:59
the valley. Historically,
41:01
the Salish tribe of the Flathead Nation
41:04
lived in Bitterroot Valley,
41:06
and while the region experienced some settlement
41:09
throughout the eighteen hundreds, Lewis and
41:11
Clark passed through in eighteen oh five, it
41:14
lagged behind other parts of the West,
41:17
but then the discovery of gold in California
41:19
and then the increasing number of Mormon settlements
41:22
in Utah eventually led
41:24
to people striking out to find a
41:26
piece of land of their own, and in the
41:28
second half of the nineteenth century, Montana
41:31
grew enormously in popularity.
41:35
The Bitterroot Valley in the second
41:37
half of the eighteen hundreds in particular,
41:40
was super popular because it had these ample resources
41:42
for lumber and fertile farmland
41:45
for livestock and apple
41:47
orchards were really popular, and
41:50
as you can guess, the increasing number of
41:52
white settlers meant that more
41:54
land had to be found. So what
41:56
was the natural solution to this problem
42:00
genocide? Well,
42:02
at least forceful removal, So the government
42:05
removed the Salish, for whom
42:08
this was their ancestral home, of course,
42:10
and so in the eighteen seventies, with the Salish
42:12
driven out, the land of the bitter Rup was
42:15
ripe for clearcutting and apple farming,
42:18
and it was also apparently ripe for the emergence
42:21
of a seemingly new tickborn disease.
42:24
All this clear cutting to make room for
42:26
orchards and farms led to proliferation
42:29
of scrub habitat, which was
42:32
great for sheep grazing, but also
42:34
great for mice and other
42:36
small mammals, which happened to be excellent
42:39
bloodmeal host for ticks. The
42:41
first case of what we now know is
42:43
Rocky Mountain spotted Fever that we can
42:46
trace back for sure, occurred in eighteen
42:48
seventy three in Montana.
42:50
Consequences man consequences
42:53
for our actions,
42:56
and this case was not a one off.
42:58
So from that first case more followed,
43:00
and not just in Montana, Colorado,
43:03
Oregon, Idaho, Wyoming. A
43:06
lot of other places grew aware
43:08
and wary of the disease rightfully
43:10
so, and I
43:13
have to include another side note here. So for
43:15
a while it was thought that the Salish Indians
43:17
had warned the incoming white settlers
43:19
of Rocky Mountain spotted fever by
43:21
saying certain canyons in the spring in the
43:23
bitter Root were full of evil spirits. But
43:26
this is no longer thought to
43:28
be in relation to the disease.
43:31
Okay, So rather
43:33
what, at least in this book, it was
43:36
thought that the disease probably wasn't super
43:38
prevalent before the white settlers
43:41
clear cut the land and allowed for the
43:43
super proliferation of ticks.
43:46
And so anyway, with this alarming rise of
43:48
an extremely fatal disease, combined
43:51
with like the daughter and son
43:53
in law of the Montana governor dying of the
43:55
disease, the state feared
43:57
that they would lose out on prospective land
43:59
by because of this pesky
44:02
fatal illness, and
44:04
so they told the
44:07
Montana State Board of Health to do
44:09
something, and that's
44:11
exactly what they did, starting
44:14
in nineteen oh two by
44:16
appointing two young pathologists named
44:18
Louis Wilson and William Chowning to
44:21
see what they could figure out about
44:23
the disease. And that same
44:25
spring, a bacteriologist named
44:28
Earl Strain suggested a connection
44:30
between the disease and a tick bite because
44:33
he was there touring to kind of see,
44:35
oh, you know, like what can I figure out about this disease,
44:38
and he visited someone who had
44:40
Rocky Mountain spotted fever and noticed a
44:42
tick embedded in the genitals
44:46
of the sick person.
44:48
Very interesting that he just happened
44:51
to see a tick, because almost
44:53
certainly if that person was suffering
44:55
from Rocky Mountain spotted fever
44:58
and they happened to have a tick, that tick was not,
45:00
in fact the perpetrator of their
45:02
illness.
45:03
I think it speaks to the high levels
45:06
of infestation.
45:08
Around the bitter Root at the time. I no,
45:10
but I mean that's and that would explain why
45:13
you know, you had such a huge increase in cases
45:15
if oh, yeah, you know, you were just getting bit
45:17
left and right and genitals.
45:21
Well, and if you think about like the occupations
45:24
of people who were settling in the bitter
45:26
Root at this time, you're outdoors,
45:28
right, You're outdoors, especially
45:31
during that time of year, and so it's
45:33
almost unavoidable.
45:35
Yeah.
45:35
Yeah.
45:36
So so
45:38
William and Chowning took note of Strain's
45:40
observation when they were planning their research season,
45:43
which they had to do basically right away because
45:46
Rocky Mountain spotted fever season is actually
45:48
pretty short, which is great
45:51
news if you're at risk for the disease,
45:53
but a little bit challenging if you're researching
45:56
it. Joys of fieldwork
45:59
and they covered their bases,
46:01
they performed autopsies, they did epdemiological
46:04
surveys, lab studies, and
46:06
what they found was concerning. Between
46:08
eighteen ninety five and nineteen o two,
46:11
there were eighty eight cases in the Bitterroot
46:13
valley with sixty four deaths.
46:15
Wow, it's a seventy two.
46:17
Point seven mortality rate. And
46:20
they concluded that it was not contagious
46:22
from person to person and not
46:25
a result of melted snow water, which
46:27
was the leading hypothesis
46:30
at the time.
46:30
Okay, well, a good thing, right,
46:34
it would.
46:34
Be hard to avoid melting snowwater. Yeah, melted
46:36
snowwater. And so they suspected instead
46:39
that it was caused by a protozoman that
46:41
they had found in some of the tick samples that
46:43
they had dissected and stuck under
46:45
a microscope. Interesting, and so by
46:47
the end of this first season of their research
46:50
they had a nice little disease ecology cycle
46:52
all laid out. The woodticks
46:54
transmitted the protozoan to humans, and
46:56
ground squirrels aka gophers
46:58
were the disease reservoirs. This
47:02
was an untested hypothesis, but that
47:04
didn't stop reports of it in the news because
47:06
people were hungry for
47:09
information about it. They were like, we
47:11
want to know how to protect ourselves. But
47:14
just knowing or thinking that
47:16
ticks were responsible for the disease
47:19
didn't really do that much because
47:22
ticks were absolutely everywhere
47:25
in the spring in the bitter Root, and so
47:27
the only way to avoid them would be to not
47:30
live or work there, which was not the solution
47:32
that the state was looking for. And
47:35
the only practical step, in their eyes,
47:37
which wasn't really practical at all, was to
47:39
eliminate the ticks themselves or
47:42
the gophers ever.
47:43
Thought to be the hosts. Oh gosh.
47:46
So in the spring of nineteen oh
47:48
four, the residents of the bitter Root took
47:50
this to heart.
47:50
They burned, and they burned.
47:52
Vegetation, and they set out poisoned
47:55
grain to kill the gophers, which
47:57
actually killed a lot of game animal gamers
48:00
and other animals.
48:02
And they also got.
48:03
A bunch of sheep to eat the grass that
48:06
the tall grass that they thought was
48:08
the ticks habitat. Oh dear,
48:11
But it's nearly impossible
48:13
to get rid of ticks. You
48:16
need possums, Sarin, We
48:18
need possums to
48:20
set loose.
48:21
The possums don't do that.
48:23
I feel like maybe we shouldn't gamble
48:27
through the ecological dye in that way.
48:31
So the next best thing, though,
48:33
was just to remove a tick as soon as
48:35
you saw it attached, right, and
48:38
people were encouraged to treat it.
48:40
Like a snake.
48:40
Bite like a venomous snake bite, dab
48:43
some carbolic acid on the side of the bite right
48:45
away. So then people had a lot of acid
48:47
burns, accidental spills.
48:50
Infections, et cetera.
48:52
I mean, basically, the bottom line is that, you
48:54
know, though these efforts had led to some
48:56
fundamental knowledge being gained, the
48:58
application to prevention simply
49:01
wasn't there, right, And so
49:04
more help was called in in the form
49:06
of Charles Wardell Styles.
49:08
Does that name sound familiar to you, Yeah, it sounds
49:11
very familiar. What else did he do? Hookworm?
49:14
Oh, that's right.
49:18
He discovered or
49:21
identified the second species of hookworm
49:24
in the Americas. Yeah,
49:26
and he I think he played a role in
49:29
I don't remember, but I think he played a role in determining
49:31
that it was the cause of the widespread anemia
49:33
in the South.
49:34
Ah. And he's Harry Styles
49:36
is great grandpa exactly
49:39
exactly. I'm
49:41
so hip just
49:44
dropping those names.
49:47
My god.
49:49
Okay, So anyway, so Styles
49:52
set out to basically test the ground
49:54
squirrel tick protozoan
49:57
life cycle that Wilson and Chouning had laid
49:59
out. He was enthusiastic
50:02
about the hypothesis early on, but he
50:04
was a little bit close minded when it came
50:06
to any challenge to the accepted
50:08
dogma of the time, which
50:12
was and this is news to me, but apparently
50:14
for a while it was believed that that
50:17
arthropods could transmit protozoa,
50:21
but were not capable of transmitting
50:24
bacteria other than accidentally,
50:27
like a fly could accidentally, I
50:29
don't know, give you an infection because
50:32
they.
50:32
Stepped in poop or something exactly.
50:35
But mosquitoes and ticks and whatever
50:38
weren't capable of actually completing
50:41
the life cycle I bacteria.
50:43
Am that's so interesting.
50:47
Yeah, So when he searched for
50:49
this, this supposed protozoan in
50:51
the ticks and the blood of the victims, he
50:54
came up empty handed again and again.
50:57
But instead of saying, you know, well
50:59
the may have something to do with it, but
51:02
the protozoan probably doesn't, he
51:04
openly refuted and
51:07
dismissed the existing hypothesis.
51:10
And he was started to say,
51:12
like, oh, you know what, these people or
51:14
these residents are overreacting. Ticks
51:17
aren't involved. It's probably snowmelt
51:19
all along. So
51:23
and it's in a way, this
51:26
contemptuous criticism actually
51:29
was beneficial for the research of Rocky Mountain
51:31
Spotted Fever because it drew
51:34
such attention from other researchers,
51:37
including a pathologist from the University
51:40
of Chicago named Howard
51:42
Taylor Ricketts.
51:45
Ricketts RICKETSS.
51:49
Rickets set up a correspondence
51:51
with Chowning, saying that he believed
51:54
their hypothesis had gotten unfair
51:56
treatment by Styles, and
51:58
Chowning was like, I agree.
52:00
Also, I've been doing some side experiments
52:03
in my spare time, including a little bit
52:05
of medicalized torture.
52:07
Oh great.
52:08
So he had obtained quote
52:10
consent from two people to
52:13
attach ticks to them which
52:15
had been feeding on a man who died of
52:17
Rocky Mountain spotted fever. Oh,
52:20
they both got sick with the disease
52:22
and recovered, And so
52:25
Chowning was like, must be ticks.
52:29
So anyway, Ricketts when
52:31
he told Rickets about this, Rickets just didn't
52:33
acknowledge it. Apparently okay' denounce
52:36
them, but he didn't acknowledge it. And he was like, I'm
52:38
gonna do my own research. And
52:41
so he went to Montana, okay, But
52:43
the state had no money to give him, and
52:45
so he and Wilson and Chowning had to
52:47
find their own way to pay. So they like
52:49
cobbled together a bunch of resources,
52:52
and in nineteen oh six, Ricketts set up
52:54
a laboratory in a tent on
52:57
the grounds of the Northern Pacific Hospital
52:59
in Missoula.
53:01
So he was just like in a tent.
53:03
And that spring and summer proved
53:05
very productive for Rickets and another
53:08
researcher named Walter King, who joined
53:10
in on the research. But it must
53:12
be said that this wasn't a super collaborative
53:16
project each one of these
53:18
men for the most part, maybe you know, Chouning
53:21
and Wilson worked together, but like Rickets
53:23
and King were very much
53:26
like, this is my project, and I want
53:28
to do it my way, and I want research, and
53:30
I want publication priority, and I want
53:32
blah blah blah.
53:34
So anyway, and.
53:37
So first they found Ricketts
53:39
and King found that they could cause the disease in
53:41
a guinea pig by injecting serum
53:43
into the animal, and they could sustain
53:46
the infection by alternating infecting
53:48
a guinea pig and then a monkey, and then a
53:50
guinea pig and then.
53:51
A monkey, which then enabled
53:54
year round research. Okay,
53:56
that makes sense.
53:58
Yeah, Then at the very end of this botted
54:00
fever season, both Ricketts and King demonstrated
54:02
that ticks can cause infection, and
54:05
they did this by attaching a tick to a guinea
54:07
pig and then disease
54:09
resulted. Ah
54:11
and this was a super exciting finding, but
54:15
it came at just the wrong time for
54:17
them because it was the end of
54:19
the season and soon there would be no more ticks
54:21
to be found. Back
54:24
in Chicago and Washington, Rickets
54:26
and King tried to keep these tick experiments
54:29
going by advertising
54:31
in like Montana papers for anyone
54:34
who could find a tick, a live
54:36
tick to send it their way. At
54:39
one point they offered a financial incentive
54:41
of ten dollars in gold for anyone
54:43
who could deliver fifty or more live ticks.
54:45
Oh my gosh, citizen science.
54:50
But they never got any. They had to wait until the spring.
54:53
Okay, and mid April nineteen
54:55
oh seven saw the first victim, a twenty
54:57
six year old lumberman whose family
54:59
refus used to allow Ricketts to draw any
55:01
blood. Ricketts was peeved
55:04
about this, and so he asked the secretary
55:06
of the State Board of Health to do
55:08
something about it, And so he
55:10
drew up an official looking document saying
55:13
that the family must cooperate with the
55:15
investigation and
55:17
then he told Rickets,
55:20
hey, don't let anyone get too close
55:22
to look at this because in truth, I
55:24
have no authority to issue it. So
55:29
you know, oh
55:31
my gosh, and people wonder
55:34
why there's deeply rooted mistrust
55:36
in.
55:37
The medical establishment and
55:39
the government research and authority.
55:42
Yeah, okay, goodness.
55:44
So anyway, in nineteen
55:46
oh seven, Rickets concentrated
55:49
on finding out the pathology of the infection
55:51
in ticks, still without knowing what
55:53
the causative agent was, and he determined
55:56
that a small proportion of female
55:58
tics could transmit the path into their offspring,
56:01
so larval takes.
56:02
Could be infectious. Awesome, which
56:04
is a great finding.
56:05
And then in January of nineteen oh nine
56:07
he seemed to finally hit the jackpot when
56:10
he published a paper in which he described
56:12
the teeny tiny basillis cox
56:14
of bacillis that was the causative
56:16
agent of Rocky Mountain spotted fever. He
56:19
had detected ample amounts
56:22
of the bacteria and eggs of infected females,
56:24
and while he was unable to culture
56:27
the bacteria, he was confident in his
56:29
finding.
56:30
Yeah. Yeah,
56:33
it's I mean, it's pretty cool.
56:35
His achievements, Like people were psyched
56:37
about this because he had done
56:39
I mean, he had done microbiological research,
56:41
he had done ecological research, he
56:43
had done some medical research, and
56:46
so his achievements won him praise and
56:48
opportunities left and right, and even
56:51
the state of Montana recognized his
56:53
work by writing in a bill in
56:55
nineteen oh nine that would fund
56:58
a bunch of his research on unspotted
57:00
fever over the next couple of years. Unfortunately,
57:04
though, the funds were suspended
57:06
when the state realized that they had allocated
57:09
more money than they were going to collect
57:11
in revenue, and
57:13
so Ricketts's work was put on hold.
57:16
Oh Man, and even though his colleagues in
57:18
Montana encouraged him to stick
57:20
around get private funds to bridge
57:22
the gap, Ricketts was like, no,
57:25
I've got so many opportunities here. I'm
57:27
going to Mexico to solve the question
57:30
of another spotted fever like disease,
57:33
typhus.
57:34
Ah.
57:35
So then he went down to Mexico City.
57:38
But it was only after he arrived in
57:40
Mexico City in December of nineteen
57:43
oh nine when he learned that
57:45
the big puzzle pieces of Typhus
57:47
had already been put together. The
57:50
vector animal model.
57:53
You know, it was a lot of the stuff
57:55
that had drawn him to study it
57:58
was already discovered, identified,
58:01
done, but he gamely
58:04
stayed on and tried to figure out the causative
58:06
agent, which he suspected might
58:08
be very similar to Rocky Mountain spotted
58:10
fever.
58:12
So then in early nineteen.
58:13
Eleven, Ricketts got word that
58:16
it finally looked like the Montana funds
58:18
were coming through, and he was super
58:20
happy, but he was not incredibly
58:23
eager to leave, despite
58:25
you know that he was working under very
58:28
dangerous conditions. There was like no protection
58:30
against Typhus. In his letters
58:32
to his friends, he wrote, like, my
58:34
wife is very upset with me.
58:36
She's very scared for me. Like if she
58:39
knew what I was doing, she'd be
58:42
wanting me to come back. But
58:46
he wanted to see the project through to
58:49
the end. And so just as tick season
58:51
was starting in Montana, just as he was like
58:54
trying to get up there, he came down
58:56
with Typhus and died May
58:58
third, nineteen ten, at the age of thirty
59:01
nine.
59:02
No.
59:03
Yeah, his death
59:06
was a huge blow to spotted
59:08
fever research, and it also
59:10
established a very tragic pattern.
59:15
If the first decade of the nineteen
59:18
hundreds was characterized mostly by
59:20
research on the causative agent and medical treatments
59:22
for Rocky Mountain spotted fever. The second
59:24
decade looked towards the tick for
59:26
answers by the late
59:29
nineteenth century, when the focus on Rocky Mountain spotted
59:31
fever was heating up. Entomology
59:33
and medicine were two
59:36
totally different fields, particularly
59:39
in North America. Research
59:42
combining the two was conducted
59:44
only rarely, such as with like
59:46
yellow fever research in Panama, for instance.
59:50
Largely entomologists played the role
59:52
of helping combat agricultural
59:54
pest arthropods or
59:56
doing like academic foundational
1:00:00
biology research, and
1:00:02
medical doctors and researchers dealt
1:00:04
with human diseases, how
1:00:06
it worked in the body, how to control it,
1:00:09
and there often wasn't a lot of opportunity
1:00:12
for overlap. Rocky
1:00:14
Mountain spotted fever, however, required
1:00:16
a full understanding of the vector
1:00:19
tixie cology, like its life
1:00:21
cycle, hosts, behavior, etc.
1:00:23
As well as the characteristics of the disease
1:00:26
bacteria, pathogenesis, etc.
1:00:29
And you might.
1:00:30
Instinctively think that public health
1:00:32
researchers or physicians and
1:00:34
entomologists working together would
1:00:37
be the best way to make progress. But
1:00:39
then maybe you forgot about ego. After
1:00:44
Ricketts met his untimely end,
1:00:47
there was maybe a bit of a vacuum in the Rocky
1:00:49
Mountain Spotted Fever research arena in Montana.
1:00:53
The head the secretary
1:00:56
of the state Public Health Department, whose name
1:00:58
was Tuttle, appointed a thing physician
1:01:00
named mcclintick to continue work
1:01:02
on the project. But then when
1:01:04
he arrived, he found an entomologist
1:01:07
named Robert Cooley had rudely started
1:01:09
on a bunch of control efforts on
1:01:11
his own, and neither was
1:01:13
willing to seed any ground for publication
1:01:16
priority or research area.
1:01:19
And apparently neither was willing to work together.
1:01:21
Oh my gosh, I know, get
1:01:24
over yourselves. Get over it.
1:01:26
So the physician McClintic believed,
1:01:29
because it's a human disease, it's a physician or.
1:01:31
A public health problem.
1:01:32
And then entomologist was like, no, it's
1:01:34
a tick transmitted disease, so that
1:01:36
calls for a tick control expert.
1:01:39
No, it's all of these just
1:01:41
were together. Uh
1:01:43
good, I know.
1:01:44
Oh, it's just like goes on and on, this
1:01:47
sparring over funds. It's actually
1:01:49
spilled over to the federal level and
1:01:52
resulted in Cooley the entomologist, losing
1:01:54
support for his work. Oh so
1:01:57
then mcclintick, who was the physician,
1:01:59
was like, a right, I'm gearing up to do some
1:02:01
tickwork, setting up giant vats to
1:02:03
dip the livestock in
1:02:06
to try to prevent tick infestations on livestock.
1:02:09
And I'm going to initiate a massive project to
1:02:11
identify the reservoir of the bacterium.
1:02:14
But that second project was
1:02:16
mostly just destroying all small
1:02:19
wild mammals like pine squirrels,
1:02:21
yellow billy chipmunks, wood rats, woodchucks,
1:02:23
weasels, badger, and of course the infamous
1:02:25
gopher.
1:02:26
Cool cool, that's
1:02:28
not the way you do it, by the way to control
1:02:31
ticks. That doesn't work.
1:02:34
And so while he was able
1:02:36
to rule out several of the species is playing
1:02:39
a major role in the infection cycle, such as badgers,
1:02:42
he had a hard time finding a single
1:02:44
smoking gun species responsible
1:02:46
for the disease.
1:02:48
And he would never.
1:02:49
Find it because
1:02:51
he died of Rocky Mountain spotted fever.
1:02:53
In nineteen twelve.
1:02:54
Oh my god, just a year after
1:02:56
starting his research in Montana.
1:02:58
Oh that's sad.
1:03:00
It's really sad. Once
1:03:02
again, spotted fever research in Montana
1:03:04
was left without a leader. Maybe
1:03:07
this was an opportunity for a fresh start
1:03:10
to bring together physician and entomologist.
1:03:13
I have a feeling it's not going to happen. Erin, No,
1:03:16
it didn't happen.
1:03:17
The budget and the land would be split. The
1:03:20
north part of the valley went to the US Bureau
1:03:22
of Entomology with COOLi in charge,
1:03:25
and the south part of the valley would be designated
1:03:27
as US Public Health Service land.
1:03:29
Kind of an interesting way to do it, Huh,
1:03:31
isn't it so fascinating?
1:03:34
Who did better? Well?
1:03:37
Great question.
1:03:38
So the entomologists on the
1:03:40
north side of the valley were set on just
1:03:43
livestock dipping and basically
1:03:46
taking a cattle submerging them into
1:03:49
a caroside or a pesticide to kill
1:03:52
the ticks. And so these entomologists
1:03:54
were like, all right, that this is
1:03:57
the key killing small rodents.
1:03:59
That's wayted effort. And the
1:04:01
public health folks on the other hand, were like, no,
1:04:04
we're gonna dip and kill
1:04:06
small mammals and also
1:04:08
not allow cattle to feed in
1:04:11
the western on the western side of the river, which
1:04:14
was the only side that was infected.
1:04:16
By the way. Oh yeah.
1:04:19
And so whether the dipping was
1:04:22
actually effective was called into question
1:04:24
as well. So from nineteen thirteen to nineteen
1:04:26
eighteen, the number of ticks supposedly
1:04:29
declined eighty to ninety percent, while
1:04:31
the number of cases had been reduced from eleven
1:04:34
to three. But these numbers are far
1:04:36
from conclusive, like eleven to three
1:04:39
is super.
1:04:40
Could just be seasonal variation or
1:04:42
whatever.
1:04:43
Exactly exactly, And
1:04:46
eradication, which was the promised
1:04:48
end of these projects, was not
1:04:50
on the horizon. The
1:04:53
tick must be destroyed. Killing
1:04:55
small animals wasn't doing it. Dipping
1:04:57
cattle wasn't doing it. Maybe a vaccine
1:05:00
could work.
1:05:01
By the way, that's our title.
1:05:04
The
1:05:12
before Ricketts died, he published
1:05:14
his preliminary findings of this bacterium,
1:05:17
but the debate continued with
1:05:20
still the protozoan leading the pack.
1:05:22
Gosh, I know.
1:05:24
The pathologistes Bert
1:05:26
Wallbach.
1:05:29
Like Wallbachia. Oh that's
1:05:31
exciting. Yeah.
1:05:33
He decided to give it a shot, and
1:05:35
he also observed teeny tiny
1:05:37
bacteria like things in the ticks, their
1:05:39
eggs, and the blood of humans and animals
1:05:42
that had spotted fever. Okay, but
1:05:44
he wasn't sure that they were actually bacteria
1:05:47
because he was like, it doesn't make sense,
1:05:49
they live entirely within the
1:05:51
cells of the animals. So
1:05:54
this has got to be some new kind of micro
1:05:56
organism somewhere in between protozoa
1:05:59
and bacteria.
1:06:00
I mean yeah, I mean wrong,
1:06:03
He's not wrong.
1:06:04
Like, and
1:06:08
even though he was pretty certain he had discovered
1:06:10
the causative agent, which he called dermo
1:06:12
CenTra zenus rakhetzi, others
1:06:14
weren't convinced, chiefly because he was
1:06:16
unable to culture the organism in.
1:06:19
Media in a lab. Of course he was,
1:06:22
he.
1:06:22
Was, like, he was like, listen, like,
1:06:25
I understand that these postula its are important, but
1:06:27
like we have to evolve, like we're
1:06:29
learning new things.
1:06:30
Maybe we should look at different criteria. Yeah,
1:06:34
he was right, He's right.
1:06:39
But then the discovery of the causative agent
1:06:41
of Typhus forced researchers
1:06:44
to accept that these intracellular
1:06:47
microbes might actually be real and
1:06:50
maybe a new type of microbial life,
1:06:52
or at least a new version of
1:06:55
what we've already seen. And eventually
1:06:57
the name that Wollback had given for the spotted fever
1:06:59
back Bacterium was changed to Rakkeetzier
1:07:01
rakeetzii, giving rise to a whole
1:07:04
new genus of pathogenic intracellular
1:07:06
bacteria cool. So
1:07:09
by the nineteen twenties, the causative
1:07:12
agent of Rocky Mountain spotted fever had been discovered
1:07:15
and the life cycle had been outlined.
1:07:17
But this knowledge didn't translate
1:07:20
into live saved yet again. Rather,
1:07:23
the incidents of the disease, as well as its
1:07:25
mortality, seemed to be on the rise.
1:07:28
For instance, in nineteen twenty one, all
1:07:30
eleven cases of Rocky Mountain spotted
1:07:32
fever died. Land
1:07:35
prices reflected this. They were
1:07:37
dropping from one hundred and twenty five dollars
1:07:39
per acre to fifteen dollars
1:07:41
per acre in some places. Oh also,
1:07:44
fifteen dollars per acre.
1:07:46
Can even imagine should
1:07:48
have bought erin actually missed out?
1:07:51
We did, and
1:07:54
tourism obviously plummeted.
1:07:56
No one wanted to go to a place where you could catch
1:07:59
spotted.
1:07:59
Fever and one hundred percent of you would die.
1:08:02
Yeah, yeah, And matters
1:08:04
were only made worse when the
1:08:06
first state bacteriologist, Arthur
1:08:08
McCrae, died of Rocky Mountain
1:08:10
spotted fever in nineteen nineteen.
1:08:12
Oh my gosh, eron, how many people are going to
1:08:14
die from this? There's more?
1:08:17
Okay, So
1:08:20
panic was at an all
1:08:22
time high, so the
1:08:24
state finally acquiesced to providing
1:08:26
funds to create a laboratory whose
1:08:28
main focus was to stop the problem
1:08:31
of spotted fever.
1:08:33
The quote Schoolhouse Lab was established
1:08:36
in an abandoned schoolhouse a couple
1:08:38
of miles from Hamilton, Montana, in
1:08:40
the Bitterroot Valley. There,
1:08:43
lab and ecological facilities were
1:08:45
built or cobbled together
1:08:47
where researchers could actually do the work
1:08:49
that they had been doing in their spare time in
1:08:52
makeshift tents and distant university
1:08:54
labs for years. And to
1:08:56
head this new research venture, two
1:08:59
people were appointed, physician Roscoe
1:09:01
Spencer and entomologist Ralph
1:09:03
Parker.
1:09:04
Parker, I all right, another
1:09:07
physician and another entomologist.
1:09:10
Are they going to work together this time? Well,
1:09:13
this is where the romance comes in.
1:09:15
Just going at
1:09:17
first, the old time rivalry
1:09:19
between these two professions seemed like
1:09:21
it was going to rear its ugly head yet again,
1:09:24
and they were like, oh, you know, before
1:09:26
they before they arrived in Montana,
1:09:28
I was like, oh, what about publication priority?
1:09:31
What about this? What about that?
1:09:32
But then they met in person and they were like,
1:09:35
let's work together. All of our research will
1:09:37
be published jointly.
1:09:38
So isn't that nice?
1:09:41
Is how you do it? That's how you do it.
1:09:44
So Parker, the entomologist,
1:09:46
he had set his sights on big picture
1:09:49
ecological studies like huge,
1:09:51
what do we how do we find out the links between
1:09:54
ticks and these animals and spotted fever
1:09:56
and the behavior and seasonality
1:09:58
and all of these like just the
1:10:00
most fun questions, right, And
1:10:03
Spencer's like.
1:10:04
I'm gonna do a vaccine.
1:10:06
And so there had been.
1:10:08
Some research by Hideo Nogucci
1:10:10
at the Rockefeller Institute that was
1:10:13
promising in terms of spotted
1:10:15
fever vaccines, and in nineteen
1:10:17
twenty three, Nogucci had declared
1:10:20
that he had developed an effective vaccine. It
1:10:22
just needed to be tested in humans. So
1:10:25
who better to volunteer than some of
1:10:27
the laboratory staff at the Schoolhouse
1:10:29
Lab in Hamilton. For sure, incidents
1:10:32
of the disease was disturbingly high.
1:10:35
The vaccine was not.
1:10:37
Without side effects, but
1:10:39
it seemed to be effective and at least reducing
1:10:42
the severity of illness if exposed
1:10:44
to the disease. All right, But
1:10:47
because the efficacy of Nogucci's vaccine
1:10:49
remained doubtful, Spencer, the
1:10:51
physician involved in the project continued
1:10:54
his own work on a vaccine, work
1:10:57
which ended up being delayed because
1:11:00
tularimia, another disease,
1:11:02
started popping up in the Bitter Root
1:11:04
Valley.
1:11:05
Oh my gosh, this does not make me want
1:11:07
to visit this part of Montana.
1:11:09
Oh my gosh. What I mean?
1:11:12
First of all, Okay, that
1:11:15
was not the
1:11:18
image I was trying to portray with this
1:11:20
history, and I feel now very bad
1:11:22
about it because it is absolutely
1:11:24
beautiful. And yes
1:11:26
there are ticks, but we know a lot more about
1:11:28
Rocky Mountain spotted fever. We know a lot more about
1:11:31
how to protect ourselves and if
1:11:34
there's ever an area where
1:11:36
the physicians are probably keyed
1:11:38
into, Yeah, that makes sense.
1:11:41
Signs you symptoms, you'd get doxycycling.
1:11:43
If you walked in and said I had a fever.
1:11:46
You're like, I went hiking in the bitter Root. Here's
1:11:48
some doxy ceco.
1:11:50
I'm just kidding. You don't give it prophylactically,
1:11:52
but anyhow.
1:11:56
So okay, tularimia
1:11:58
popped up. Both as Ann
1:12:00
Parker, the heads of the project, became ill,
1:12:03
and they wouldn't be the last to fall
1:12:05
during this work.
1:12:07
No, Aaron, I don't know if my heart
1:12:09
can take this. I'm so sorry.
1:12:11
This is the whole romance. This is
1:12:14
not that.
1:12:14
I think it was like romance, meant in
1:12:17
the way that was like.
1:12:20
Tragedy. Oh yeah, those are
1:12:22
two different categories of
1:12:24
film. I
1:12:26
don't know, are they? Like a tragic movie
1:12:28
could be romantic at the same time and vice versa
1:12:33
Romeo and Juliet. Yeah, I don't like
1:12:35
that one.
1:12:36
Well, anyways, regardless,
1:12:39
let's learn more about the fallen researchers.
1:12:42
Okay, student research assistant
1:12:45
William Geddinger died in nineteen
1:12:47
twenty two of spotted fever. Field
1:12:49
assistant George Henry Cowan, who had
1:12:52
worked for over a decade on the
1:12:54
disease, died in nineteen twenty four,
1:12:56
and another student researcher named Albert
1:12:58
Curley died in nineteen twenty eight
1:13:01
of spotted fever. In
1:13:03
nineteen twenty five alone, six
1:13:06
people working at the Schoolhouse Labs
1:13:08
became infected with either
1:13:11
spotted fever or tularimia.
1:13:13
Oh my goodness.
1:13:14
The Schoolhouse Lab was
1:13:18
notoriously and
1:13:20
deservedly so, an incredibly dangerous
1:13:22
place to work because there was no
1:13:25
biocontainment facilities and
1:13:27
spotted fever ridden ticks were crawling
1:13:30
all over the place. Oh no, Like they would
1:13:32
have rabbits that they would infect and then the ticks
1:13:34
would just be like your tick falls off and then
1:13:36
it could go and.
1:13:37
Oh get up on a lab worker.
1:13:39
Dogs wandered in and out, bringing ticks
1:13:41
with them. I mean they didn't
1:13:44
have the best facilities, right. Part
1:13:46
of it was funds, Like if
1:13:48
there's a lesson here, and it's about funding
1:13:50
disease research as
1:13:52
usual. There's
1:13:55
a famous book called Microbe Hunters by
1:13:57
Paul Dacreefe that tells
1:13:59
the romantic and swashbuckling tales
1:14:02
of like early microbiologists and well
1:14:05
micropunters, and it
1:14:08
includes the story of the Rocky Mountain spotted fever
1:14:10
researchers, which enraged the
1:14:12
residence of the Bitter Root because it portrayed
1:14:14
them all as like cowering in their cabins
1:14:17
hiding from this dreaded disease. But
1:14:20
I mean people were rightfully scared of spotted
1:14:22
fever, and so when Spencer rolled out testing
1:14:24
of his vaccine in nineteen twenty five,
1:14:27
people like both workers
1:14:30
at the lab as well as residents
1:14:32
eagerly volunteered and
1:14:34
it seemed effective in at least reducing
1:14:37
the duration and severity of the illness.
1:14:39
Okay, so overall, retrospective
1:14:42
studies showed that vaccinated people had a
1:14:44
seventy five percent lower fatality
1:14:47
rate than those who were unvaccinated.
1:14:49
What that's amazing.
1:14:51
Yeah, yeah, so you
1:14:54
know, but the
1:14:56
hazardous working conditions remained
1:14:58
a concern, and so the state finally
1:15:01
put together funds to build new facilities.
1:15:04
But where should they go? Should they move to Missoula,
1:15:06
where the University of Montana was located,
1:15:08
But maybe that was too far from the field, and
1:15:11
so we should keep it close to
1:15:13
Hamilton, And so it was
1:15:15
decided that it was that it would be built on
1:15:17
the east side of the river in Hamilton,
1:15:21
which had always been spotted fever
1:15:23
free.
1:15:23
Oh no.
1:15:26
This caused quite a bit of
1:15:28
a stir as people became concerned
1:15:30
that the disease would become established
1:15:32
on the east side, or that infected
1:15:34
ticks would escape, or children playing
1:15:37
in the yards of the lab would get infected. But
1:15:40
tons of special precautions were put in place,
1:15:43
including like amoat and heavy
1:15:45
duty sterilization procedures WHOA
1:15:47
and work began. Ultimately,
1:15:51
the residents of Hamilton warmed to the lab
1:15:53
and they would occasionally like lead out of
1:15:56
town visitors through the building. And then that
1:15:58
became problematic because the recent were
1:16:00
like, you're putting yourselves at risk. We
1:16:03
need to shut this down, like you
1:16:05
need to sign in, you need to have somebody
1:16:08
supervising this. So but
1:16:10
anyway, the availability of a vaccine
1:16:12
also alaid some of these fears. But
1:16:15
the vaccine was not a permanent solution because
1:16:17
in order to make it, researchers
1:16:19
had to collect or rear thousands
1:16:22
of ticks, get them infected,
1:16:24
and then grind them up and then
1:16:26
turn that into a vaccine.
1:16:28
Oh that's what they were using. Okay,
1:16:30
mm hmm.
1:16:31
And there wasn't much work that had been
1:16:33
done on streamlining the production process,
1:16:36
and nor would there probably be,
1:16:39
since the market for the vaccine was relatively
1:16:42
like low, only in the Western States.
1:16:44
Yeah, or was it so?
1:16:49
Throughout the nineteen thirties, a mysterious
1:16:51
typhus like illness was noted along
1:16:54
the eastern seaboard of the US as well
1:16:56
as in Brazil, and it seemed to be associated
1:16:58
with.
1:16:59
A tick bite.
1:17:00
And while initially it was thought to be a disease distinct
1:17:02
from spotted fever, like doctors
1:17:04
would say, oh, I would say this is spotted fever
1:17:06
if I were in Montana. But
1:17:09
ultimately microbiological research showed
1:17:11
it to be one and the same. And this
1:17:13
development was pretty crucial since it came
1:17:16
around the same time as the Great
1:17:18
Depression was sinking its teeth into
1:17:20
everything, including
1:17:23
scientific research funding. So
1:17:26
funding for the Rocky Mountain
1:17:28
Laboratory was threatened. And
1:17:31
in response to this, one
1:17:33
person, one researcher replied quote,
1:17:36
and I'm including this quote because I think it's relevant
1:17:40
to.
1:17:41
Today and always.
1:17:44
If the government should discontinue this activity
1:17:46
in the light of our present knowledge, the
1:17:48
person's responsible for such action would,
1:17:51
in my opinion, be morally
1:17:53
responsible for the deaths which will
1:17:55
occur as a result of the lack
1:17:57
of material. I may
1:17:59
add that only a few days ago
1:18:02
a request was received from the Army
1:18:04
for a large quantity of this material
1:18:06
to be used for the protection of its forces
1:18:09
in the field.
1:18:11
So sounds strangely
1:18:14
familiar in our affurent climate.
1:18:19
And that's all I'm going to say about that.
1:18:22
It's like the government doesn't want to fund this anymore,
1:18:25
but yet they want it so
1:18:28
anyway.
1:18:30
Fortunately, you know.
1:18:31
Maybe this has cause for optimism. The
1:18:34
funds were preserved the lab
1:18:36
stayed and placed, and actually
1:18:38
some Civilian Conservation Corps
1:18:40
CCC camps, which was like part of the whole,
1:18:43
you know, Roosevelt's New Deal,
1:18:45
were established in the bitter Root
1:18:47
to help collect ticks and
1:18:49
to do this research for vaccine
1:18:51
productions. They had tons of people coming
1:18:54
in to work there, which was
1:18:56
actually also a problem because there wasn't
1:18:59
enough vaccine to vaccinate.
1:19:00
The newly arrived workers. But anyway,
1:19:04
so until the mid nineteen.
1:19:05
Thirties, research at the Spotted Fever Lab
1:19:07
in Hamilton had focused on just
1:19:10
that, hence its name, which
1:19:12
is the Spotted Fever Lab. Maybe
1:19:14
some dips into tularimia, but developments
1:19:17
in the mid nineteen thirties would greatly
1:19:19
expand its role and give it the name Rocky
1:19:21
Mountain Laboratory.
1:19:23
But that, like Rocky Mountain Labs, is
1:19:25
still a thing today.
1:19:27
Oh yeah, these
1:19:29
are its roots.
1:19:30
Yeah that. I never knew that. And when
1:19:32
you said Rocky Mountain Labs earlier, I was
1:19:34
like, I never
1:19:36
would have. I don't know how I never would
1:19:38
have made a connection between Rocky
1:19:41
Mountain, Spotted Fever and Rocky Mountain Labs. I
1:19:43
never I never made that connection before.
1:19:45
Oh my gosh, and it's it's so wild
1:19:47
because like that's always been like
1:19:50
well throughout my PhD. I was like, Oh, that's
1:19:52
that's my dream place to work. I want to work on
1:19:54
racketzias in Rocky On in
1:19:57
RML.
1:19:57
Yeah, in beautiful ham.
1:20:00
And But like I didn't know
1:20:02
any part of this history, and I also didn't
1:20:05
know the incredible significance
1:20:07
that this lab has had, like
1:20:09
not only on Rocky Mountain spotted fever research,
1:20:12
but as we're about to find out even
1:20:14
more research.
1:20:15
Ooh
1:20:18
okay.
1:20:19
So in nineteen thirty
1:20:21
six, a researcher at Rocky
1:20:24
Mountain Laboratory named Harold Cox had
1:20:26
been experimenting with different ways
1:20:28
to grow ricketzier outside of ticks,
1:20:31
because he was like, I want to put together
1:20:33
a better method of vaccine production. One
1:20:36
day he ran out of the tissue that
1:20:38
he had been using mid experiment, and
1:20:42
rather than scrapping the whole thing, he
1:20:44
reached for some yolksac that
1:20:47
he had put in the fridge. You
1:20:49
have that just like I guess
1:20:51
well, they were doing like egg yambrane
1:20:54
whatever, And the next day
1:20:56
he found it teeming with ricketzia.
1:20:59
He was like, oh my gosh, what
1:21:02
he wrote to everyone.
1:21:03
People were super skeptical and then they saw it in
1:21:05
person and they were like you kidding me.
1:21:07
Good job.
1:21:10
And this accidental
1:21:12
discovery had huge implications
1:21:15
but not just for spotted fever research,
1:21:18
but other riquettsial diseases. And
1:21:20
I know that, like we haven't done a Typhus
1:21:22
episode, but like Typhus
1:21:25
is really bad. Yeah, I mean
1:21:27
you talk about one of the big killers of
1:21:29
especially like you know, wartime
1:21:32
and any sort of like civil unrest
1:21:34
areas, Like Typhus was
1:21:37
massive. Yeah, so it's
1:21:39
still it's still massive.
1:21:42
Yeah.
1:21:42
Yeah, So Typhus was
1:21:44
was a huge one, and so so
1:21:46
spotted fever. Yeah, across the US
1:21:49
and inter Central and South America, incidents
1:21:51
of it ran pretty low. Of course, it was very
1:21:53
deadly and so that was a huge cause for concern.
1:21:56
But of even more interest was this
1:21:59
the big killer typhus, Especially
1:22:02
as World War two began and
1:22:04
as US soldiers began to be stationed
1:22:07
in regions where it was endemic.
1:22:11
Cox's yolksac method
1:22:13
provided a cost efficient way to
1:22:15
produce the volume of vaccines that
1:22:17
had long been sought after huh.
1:22:20
This discovery turned Rocky
1:22:22
Mountain Laboratory into a national
1:22:25
vaccine factory for typhus and
1:22:27
yellow fever and others during
1:22:29
World War two. Like it turned into
1:22:31
just pumping out vaccines.
1:22:33
Wow, I did not know that.
1:22:35
And it played such a hugely important
1:22:38
role during World War two that there were
1:22:40
armed guards like from
1:22:43
you know, armed forces around
1:22:46
there around the clock twenty four to seven
1:22:48
to make sure that like nothing happened to the lab
1:22:51
in old Hamilton, Montana, like tiny
1:22:54
town.
1:22:54
So anyway, super cool.
1:22:57
And then while at Rocky Mountain Laboratory,
1:23:00
Cox also developed the complement
1:23:02
fixation test, which allowed
1:23:04
for diagnosis of ricketzial diseases.
1:23:08
Wow, that's a big deal.
1:23:10
That's a very big deal. So VACU
1:23:12
Mountain Lab, Rocky Mountain Lab.
1:23:17
The discovery of antibiotics that were
1:23:19
effective against ricketzial diseases
1:23:21
in the nineteen forties and the nineteen fifties,
1:23:24
they took some of the urgency out of the
1:23:26
preventative or treatment research programs
1:23:29
for spotted fever. Researchers
1:23:31
could now focus on understanding the physiology
1:23:34
of ricketzier and the microbiology
1:23:37
of these bizarre tiny
1:23:39
bacteria, and the
1:23:42
miracle of antibiotics, as we had discussed
1:23:45
a few episodes ago, led to
1:23:47
this unfortunate decline in some
1:23:49
of the more fundamental medical entomology
1:23:51
research that had been the hallmark of the
1:23:53
Rocky Mountain Laboratory in its early decades.
1:23:57
With the combination of a vaccine
1:23:59
and antibiotics, fear of spotted
1:24:01
fever declined throughout the fifties
1:24:03
and the sixties, despite the fact
1:24:06
that it continued to pop up in new locations
1:24:08
and with increasing incidents like
1:24:10
it. If you look at a chart
1:24:14
of the cases over time, it's like
1:24:16
increasing, increasing in the late eighteen hundreds,
1:24:19
early nineteen hundreds, and then plummets, and
1:24:21
then throughout the sixties and seventies it's like
1:24:23
on the rise.
1:24:24
Oh just wait, Aaron, just okay, wait.
1:24:27
I'm very interested,
1:24:29
Okay. And
1:24:32
then budget cuts in the nineteen
1:24:35
seventies eliminated the medical
1:24:37
entomology research program at Rocky
1:24:39
Mountain lab And I don't
1:24:41
know if it's if it's back up or not. I should have checked
1:24:43
that, But and the tick collection was
1:24:45
shipped to the Smithsonian.
1:24:47
Huh.
1:24:48
Work on Ricketsie continued, and
1:24:51
Rocky Mountain.
1:24:51
Laboratories is still a
1:24:54
hugely.
1:24:55
Important side of research in general, as we mentioned,
1:24:58
and a few more pieces of the spotted
1:25:00
fever puzzle fell into place
1:25:03
during this time. For instance,
1:25:05
the recent resurgence in cases in the nineteen
1:25:08
seventies was traced to the
1:25:10
encroachment of humans into previously
1:25:12
wooded areas allah lime
1:25:14
disease surprise, surprise, and
1:25:18
most interestingly, the long
1:25:20
standing mystery of why the
1:25:22
east side of the Bitterroot River remained
1:25:24
protected from the west side
1:25:28
was solved okay by
1:25:30
Willie Burgdorfer Burgdorfer.
1:25:35
Of our lime disease episode.
1:25:39
Yet Okay, we
1:25:41
don't know.
1:25:42
So I'm so excited that I
1:25:44
get to tell you this.
1:25:45
Oh I'm so excited too, because I really was expecting
1:25:47
this story to go And then they built a lab
1:25:49
and then released infected ticks and
1:25:51
now they're everywhere, Like that's one hundred
1:25:54
percent what I expected.
1:25:55
So that's not what happened. And
1:25:58
here's why. So he
1:26:00
discovered that on
1:26:03
the east side of the river. He
1:26:06
was doing a bunch of, you know, microbiology
1:26:08
essays of these ticks, and he discovered
1:26:11
that they were infected with Ricketsia,
1:26:14
but it was a non pathogenic one,
1:26:17
and the Ricketsia in those ticks
1:26:19
prevented Racketzia ricketsii,
1:26:22
the pathogenic one from colonizing
1:26:24
the ticks interference
1:26:26
phenomenon.
1:26:27
Okay, oh
1:26:30
my god, I'm getting like chills.
1:26:33
I know, I know.
1:26:35
So researchers
1:26:38
had long made the observation that animals freely
1:26:40
passed from the east side to the west side of the river. Animals
1:26:43
were found on both sides. Like it didn't
1:26:45
make sense, right, So if
1:26:47
a tick that is infected with this non pathogenic
1:26:50
Ricketsia bites an animal
1:26:52
that is infected with spotted
1:26:55
fever Racketzia Ricketsia I, that
1:26:58
spotted fever can't establish
1:27:00
in that tick, right because the other bacteria
1:27:02
is just already there and
1:27:04
so and this bacteria also has
1:27:07
better transoviial transmission, so
1:27:10
it will not hurt the tick
1:27:13
as it's passed from female
1:27:15
tick to eggs. This
1:27:18
is so interesting, Aaron tick biology
1:27:20
is so amazing.
1:27:22
It really is very so amazing.
1:27:24
That is so bizarre.
1:27:26
So, this this interference phenomenon
1:27:28
people have like it's been discussed,
1:27:31
this type of thing, We've talked about it with Wolbacchia,
1:27:33
and like, yeah, maybe we haven't, but like we've
1:27:35
referenced it at least or alluded to it
1:27:38
in terms of like finding the certain
1:27:41
microbes that can prevent pathogenic
1:27:44
ones from establishing in a vector.
1:27:45
We talked about it with then gay fever.
1:27:48
Oh yeah, yeah, so anyway,
1:27:51
Burgdorf, Yeah, So,
1:27:53
even though Rocky Mountain spotted fever
1:27:55
has been heavily studied for over
1:27:58
one hundred years, there's
1:28:00
still a lot that we don't know about it, m
1:28:02
M, particularly when it comes
1:28:04
to the disease, reservoirs, strain
1:28:07
differences, geographic differences, climate
1:28:09
change, like the list goes on and
1:28:12
on and on, seasonality. Fortunately
1:28:15
for researchers now it's a lot
1:28:17
safer than it used to be to study.
1:28:19
And I repeat again, I
1:28:22
hope, hope, hope.
1:28:23
I haven't discouraged anyone from visiting
1:28:25
the Bitterroot Valley because you definitely
1:28:28
should do so. It's gorgeous, it's
1:28:30
amazing and anyway,
1:28:33
and you could go see Rocky Mountain Labs
1:28:36
and you could go see
1:28:38
the infamous, the famous,
1:28:40
the amazing Rocky Mountain Labs. Okay,
1:28:45
well erin, tell
1:28:47
me what's going on with Rocky Mountain
1:28:49
spotted fever today.
1:28:50
Oh oh, I'm really thrilled
1:28:52
too. After that history, we'll take
1:28:55
one quick break first. I'm
1:29:29
going to start off not where I expected
1:29:32
to start off. Because I
1:29:35
want to ask you questions.
1:29:37
Erin, Okay, Okay, I
1:29:41
want to start off with vaccine.
1:29:44
We don't have one, Erin, No,
1:29:47
there is none.
1:29:49
The one that they had developed, the
1:29:51
Parker Spencer vaccine that
1:29:54
was used, I don't know how,
1:29:56
like it's not been used for several decades
1:29:58
now, Yeah, and I I think ultimately
1:30:01
it caused some
1:30:03
side effects and possibly infection in
1:30:06
some.
1:30:06
People, if that makes sense. If they were just grinding
1:30:08
up ticks, then that would that would be Yeah.
1:30:11
It seems like Riquetsier in
1:30:13
general are a tricky bunch
1:30:15
to make vaccines for.
1:30:17
Yeah, I don't I don't know, I
1:30:20
don't know, but we don't
1:30:22
have a vaccine honestly,
1:30:25
from what it sounds like, and I'm
1:30:27
I'm sure that this is the case, it's largely
1:30:29
just because of a lack of funding and a lack
1:30:32
of interest, not just from
1:30:34
like a research standpoint, but from a pharmaceutical
1:30:37
standpoint. There
1:30:39
are not enough cases essentially
1:30:41
per year to produce
1:30:44
a vaccine. It's not like financially
1:30:46
viable, for better or for worse. It
1:30:49
is true that patients who survive
1:30:51
infection do mount a very
1:30:53
good and long lasting immune response
1:30:56
and We've also identified a number
1:30:59
of the surface protein an egen,
1:31:01
so it's certainly theoretically possible
1:31:03
to develop a vaccine. But
1:31:06
when you you know, I usually
1:31:08
use Google scholar that's
1:31:10
my preferred search website
1:31:15
for finding my papers. And
1:31:17
when you search Rocking Mountain spot of
1:31:19
Fever vaccine, you the first
1:31:22
entire page of results. There is
1:31:24
not a single paper from past nineteen
1:31:26
ninety on that page.
1:31:30
So yep, and some of
1:31:32
them are from nineteen twenty five. They're
1:31:35
probably some of the ones referenced
1:31:37
in your book. Oh my gosh's Parker
1:31:39
sponsor, right, But that
1:31:41
doesn't mean that no one's doing research on it. I
1:31:43
did find a recent paper that
1:31:46
was looking at and did
1:31:48
develop an effective wholesale vaccine
1:31:50
that they tested in dogs. I will
1:31:52
link to it, but like, I wouldn't
1:31:54
read that paper again. It was very depressing.
1:31:57
They killed a lot of dogs. Oh
1:32:00
my god. Yeah, but
1:32:02
they made a vaccine. So
1:32:05
anyways, that's the current
1:32:08
research. Let's talk about the epidemiology.
1:32:10
Okay, yes, all
1:32:13
right, So in the United States,
1:32:16
Rocky Mountain spotted fever has
1:32:18
been a nationally notifiable
1:32:20
disease since the nineteen twenties.
1:32:23
Since twenty ten, they've been calling
1:32:26
it a different name and therefore reporting
1:32:28
it a little bit differently. It's now reported
1:32:31
as spotted fever ricketziosis.
1:32:34
And the reason is we don't
1:32:36
have a good way to differentiate the
1:32:38
clinical syndrome that is caused
1:32:40
by Ricketzia RICKETSII from
1:32:43
the clinical syndromes that are caused by a
1:32:46
number of other Ricketzial pathogens,
1:32:49
including Ricketzia, Parker eye,
1:32:51
which we briefly said
1:32:54
those words earlier, ricketzial
1:32:57
pox, and a few others.
1:33:01
So kind of that's the background
1:33:03
I think to keep in mind as I'm going to talk
1:33:05
about these numbers, because this gets really
1:33:08
interesting, Okay, Okay, so
1:33:11
let's talk about you said that cases
1:33:14
were increasing, you know, through
1:33:16
the late nineteen nineties or
1:33:18
through the late nineteen hundreds right
1:33:21
after that drop off. Well,
1:33:24
if you look at the graphs of cases
1:33:27
since the year two thousand, it's
1:33:30
terrifying. It is.
1:33:33
It's an exponential growth curve, which
1:33:35
everyone is now very familiar with. We've
1:33:37
all seen a lot of those
1:33:39
these days. Okay, The
1:33:43
number of cases has increased steadily
1:33:46
just about every year. Twenty
1:33:49
eighteen was a little better than twenty seventeen,
1:33:51
but in twenty seventeen, there were over six thousand
1:33:53
cases reported, and that's up
1:33:55
from five under five hundred in the
1:33:57
year two thousand.
1:33:59
What okay, that's like
1:34:02
And I'm so embarrassed because this is literally
1:34:05
what I did my PhD on.
1:34:06
Yeah, you did it in Panama. Okay,
1:34:09
it's fine, Okay, you didn't need to
1:34:11
know these numbers. So, but here's the question.
1:34:14
We're seeing these huge increases in cases.
1:34:17
How many of these are the
1:34:20
very deadly Rocky Mountain spotted fever versus
1:34:22
other ricketzia and
1:34:25
it's really hard to say, And also how
1:34:27
much of it is Are we getting better at recognizing
1:34:29
it, are we getting better at reporting it?
1:34:33
Or are there an increase in
1:34:35
infections? I
1:34:38
think this is me thinking,
1:34:40
but also like based on what I
1:34:42
read, uh, it's likely
1:34:44
a combination of both as usual. But
1:34:47
the increase is so large over
1:34:49
such a short period of time, Like we're talking
1:34:51
twenty years, right from two thousand you
1:34:53
have under five hundred cases to over six
1:34:56
thousand in seventeen years.
1:34:58
That's massive. And this is a disease
1:35:01
that's been notifiable since
1:35:03
the nineteen twenties, and
1:35:06
our diagnostic tools are
1:35:08
not much better today than they
1:35:10
were twenty years ago.
1:35:13
Okay, the
1:35:15
case fatality rate has drastically
1:35:20
dramatically decreased
1:35:22
since the nineteen forties, since the introduction
1:35:25
of tetracyclines for treatment.
1:35:28
So in clinical reviews like
1:35:30
worldwide, even after tetracyclines
1:35:33
were introduced for treatment, case
1:35:35
fatality rates still usually
1:35:38
are about five to ten percent, usually
1:35:40
around five percent. But
1:35:43
the current case fatality rate in the
1:35:45
US, according to surveillance data,
1:35:47
is as low as zero point five
1:35:50
percent. What that's excellent.
1:35:53
It is excellent, but it bears
1:35:56
the question, is this rocky
1:35:58
mountain spotted fever or is this something
1:36:00
else? So let's look in other
1:36:02
parts of the world, what's
1:36:05
going on there? Well,
1:36:07
turns out that's hard to do. There's
1:36:12
not very good surveillance data
1:36:14
for much of the rest of the world. But
1:36:17
I did find some really good data for Mexico.
1:36:20
So in Mexico throughout
1:36:22
the two thousands, the incidence
1:36:25
of disease has also been increasing,
1:36:28
also dramatically. I don't have
1:36:30
an exact number. However,
1:36:33
unlike in the US, the case fatality
1:36:36
rate has also been increasing
1:36:39
rather than decreasing. Really,
1:36:41
the aggregate case fatality rate has been
1:36:44
between fourteen to eighteen percent
1:36:46
depending on the region of Mexico, but in
1:36:48
some years the case fatality rate
1:36:51
has been as high as forty percent.
1:36:53
Ooh, so
1:36:55
then I think, you know, there's a lot of questions
1:36:58
as to what is this.
1:37:00
Does this mean that we're looking at different diseases
1:37:03
or does it just mean that we're looking at drastic differences
1:37:05
in lack of availability of good
1:37:07
diagnostic tests, delays
1:37:10
in reaching a doctor to get
1:37:12
diagnosis or to get treatment. Another
1:37:16
issue is that a large proportion
1:37:18
of cases, not just in Mexico,
1:37:20
but in Mexico and also in the US, are
1:37:23
in children, because kids are running
1:37:25
around outside getting bitten by ticks, and
1:37:28
usually tetracyclines aren't used
1:37:30
as treatment for children because
1:37:33
it can permanently damage and discolor
1:37:35
your teeth. So
1:37:37
a lot of physicians might be hesitant
1:37:40
to prescribe doxycycling for kids.
1:37:42
But it turns out that for Rocky Mountain spotted fever,
1:37:44
it's a short enough course that it doesn't actually
1:37:46
increase the risk of tooth
1:37:48
discoloration. But maybe
1:37:51
you don't know that, and so then a kid
1:37:54
is delayed in getting the appropriate treatment
1:37:56
or receives the wrong kind of treatment,
1:37:59
and you have an increase in case
1:38:01
fatality rate, but
1:38:04
overall it's
1:38:07
less than one percent of spotted
1:38:10
fever group or keetsioses that are reported
1:38:12
in the United States are actually lab
1:38:14
confirmed.
1:38:16
Okay, so it's all
1:38:18
based on the trial.
1:38:21
Yeah, exactly. Oh and
1:38:23
the other triad piece is
1:38:26
often a tick exposure. So
1:38:28
some people say the triad is fever,
1:38:31
rash, tick exposure, or history of tick
1:38:33
exposures rather than the fever,
1:38:36
headache, and rash.
1:38:40
But not everyone reports tick
1:38:43
exposure, right, and that doesn't mean
1:38:45
that they weren't exposed, They just might never
1:38:47
have known it. Mm hmm, comforting
1:38:50
thought. Yeah, so
1:38:53
that's spotted
1:38:57
fever group, riquetsiosis, Rocky Mountain,
1:38:59
spotted fever. Today.
1:39:05
We never told Brett's.
1:39:06
Story, Okay, okay,
1:39:08
now we need to tell Brett's story. Cast
1:39:11
your mind back to twenty thirteen,
1:39:14
twenty thirteen, twenty.
1:39:16
Fourteen, twenty fourteen,
1:39:19
the summer, the summer of twenty
1:39:22
fourteen. Okay, listen, the rainy season
1:39:24
in Panama everyone, June.
1:39:27
As we mentioned, Aaron
1:39:29
Welsh did her research on tickborn
1:39:33
disease in Panama. That
1:39:35
was what her thesis was on. Our lab
1:39:38
is a disease ecology lab. We
1:39:41
studied tick
1:39:43
and other vector borne diseases.
1:39:46
Okay, my focus in particular,
1:39:48
well, my focus was the general
1:39:51
ecology of tics
1:39:54
and their pathogens as it related
1:39:56
to the climate gradient
1:39:58
across the isthmus and seasonality and
1:40:01
different animals and blah blah blah. But
1:40:05
you know, in all the research proposals
1:40:07
I ever wrote during
1:40:09
my PhD, I
1:40:12
always mentioned rakhetzi RACKETSI I, of
1:40:14
course, because it is
1:40:16
present there and it is a cause for concern
1:40:19
to So you want to understand where
1:40:21
they are, what the ticks are, and you
1:40:23
want to increase awareness of
1:40:26
a tick bite and a rash,
1:40:28
a fever and.
1:40:30
A possible headache. So June
1:40:34
of twenty fourteen, Brett,
1:40:37
my now husband, and I
1:40:39
flew back from Panama after my first
1:40:42
field season down there, to
1:40:44
California to stay with family for
1:40:46
a short time. And
1:40:49
on the plane ride back, he started
1:40:52
feeling crappy. Okay,
1:40:55
he did. He felt unwell. We
1:40:59
made it back to my brother's house
1:41:02
and I believe he had a fever,
1:41:05
but I'm sure we didn't have a thermometer. But
1:41:07
he felt he felt sick, like
1:41:09
he just really didn't feel good. And I was
1:41:11
like, gosh, like I hope you didn't come down with something,
1:41:14
you know. But he had
1:41:16
no respiratory symptoms. He wasn't coughing,
1:41:19
he didn't have you know, like
1:41:22
sore throat, any of the normal kind of
1:41:24
things I would associate with flu or a
1:41:26
cold. He just felt achy,
1:41:29
he felt unwell. He had a headache,
1:41:31
a fever. And
1:41:33
this lasted for a couple of days,
1:41:36
and then he
1:41:39
went to the bathroom. Is
1:41:43
he gonna be? Did
1:41:45
you tell him that you were going to tell this? Yes, I told him.
1:41:48
He goes, I knew as soon as you said you
1:41:50
were doing rocking Mountain spotted fever. He's
1:41:52
like, I've been waiting for this for three
1:41:54
years. Finally here. So
1:41:57
then he came out of the bathroom
1:42:00
room and he said, I
1:42:03
just I pulled
1:42:05
something. I pulled something
1:42:07
off of my
1:42:09
my the top of my butt crack.
1:42:12
And I said what and he was like yeah,
1:42:15
it was like there was a bunch of blood and some black
1:42:17
stuff. And I said
1:42:19
what. And then I grabbed
1:42:21
his arms and on his
1:42:24
wrists was a rash,
1:42:28
a red, blanching,
1:42:31
macular rash
1:42:34
that did not hurt and did not itch. And
1:42:36
oh, he also had one on his legs
1:42:38
that he hadn't even fully noticed up
1:42:41
to the blood. Okay, And
1:42:43
then he said, I pulled this thing off the top
1:42:45
of my butt. It was I. I
1:42:47
saw it. I squished it. There
1:42:50
was blood and then
1:42:52
black things, and I went and
1:42:54
I threw it in the toilet
1:42:57
and I flushed, and
1:43:01
I said, you just flush
1:43:03
a tick. You have a
1:43:05
ricketsia. You need to first
1:43:07
of all, go to the doctor. And second of all,
1:43:09
I can't believe that you threw the tick
1:43:12
in the toilet. I
1:43:14
was devastated. Oh, we all were.
1:43:16
Our whole lab knows this story. He's
1:43:19
also probably going to be like, you told it entirely
1:43:22
incorrectly, but I didn't.
1:43:24
This is how it happened.
1:43:26
Yeah, this is the This is the myth
1:43:28
as I know it now. At this point, it's legendary
1:43:31
status.
1:43:31
It was classic. I mean,
1:43:34
as soon as like and I can't I
1:43:36
will say, I can't remember if he if he had
1:43:38
the rash before he pulled
1:43:40
a tick off, or if if I didn't see
1:43:42
the rash until after he told me about pulling the
1:43:44
tick off. But as soon as he told me about that, I
1:43:47
looked and he had this rash, and I was like,
1:43:49
I knew that it
1:43:51
was. I was like, this is either racketzia
1:43:54
rakhetsi I and you're going to die,
1:43:57
or it's a lesser one, but either way, you need
1:43:59
to go get treatment. And he wouldn't listen
1:44:01
to me until we went
1:44:03
to go visit his parents, and I had to tell his
1:44:05
mother and she's the one who forced
1:44:07
him to go to the doctor and get
1:44:10
treatment because he wouldn't listen to me. So
1:44:13
thank you, Chris, because otherwise
1:44:15
he might be dead. So you went to
1:44:17
the doctor and he said that the doctor
1:44:19
like he told the doctor that
1:44:22
he thought he had rocommend and spot if you've readen, this
1:44:24
is why. And then apparently the doctor like
1:44:26
went and took his phone and then came
1:44:29
back in with his phone and was like, well, we
1:44:31
could do a test, but I think I should
1:44:33
just give you some antibiotics. And Brett
1:44:35
was like yep, and
1:44:38
he was better in a couple of days.
1:44:40
Oh well, I
1:44:43
am very glad that Brett
1:44:45
was better.
1:44:45
I'm still I'm still puzzling.
1:44:47
Over where you picked it up because you had.
1:44:49
Just been it' scuba diving
1:44:52
or something. We had been at Koiba,
1:44:54
so it could have been Koiba because we had hiked around
1:44:56
that a little bit, but also could have just been in Gamboa
1:44:59
because we went up to the ridge or whatever.
1:45:01
And well, yeah,
1:45:03
we'll never know because he threw
1:45:06
the tick in the toilet. Even
1:45:08
yesterday when I told him we were gonna tell
1:45:10
this story on the podcast, he was like, I
1:45:12
should have just thrown it in the trash.
1:45:15
I know, I know, Brett, like you had
1:45:17
killed it dead and good like,
1:45:22
oh, it could have been like.
1:45:26
My entire dissertation
1:45:29
right there, right like, at least that's a case
1:45:31
report. We could have been co
1:45:33
authors, Aarin, we could still be
1:45:36
co authors on a paper. Yeah, whip
1:45:39
my no, okay, don't jump, Brian.
1:45:46
So that's that's our story.
1:45:49
That's our story, you know.
1:45:50
Erin this I
1:45:52
feel like it lived up to my
1:45:55
expectations, my hype for this episode.
1:45:57
I had a great time me too. I
1:46:00
feel like it was back to our
1:46:02
roots in a way.
1:46:03
Yes, it really did. It felt good. It
1:46:05
felt good.
1:46:06
I was a little bit afraid to do something that was
1:46:08
like very close to my PhD, and
1:46:10
then I realized it doesn't have anything
1:46:13
to do with my PhD.
1:46:16
Well sources sources.
1:46:18
Yes, I mostly
1:46:21
used a book called Rocky Mountain
1:46:23
Spotted fever History of a twentieth century
1:46:25
disease by Victoria
1:46:28
Harden, which told
1:46:30
the complete story.
1:46:31
It was great. And
1:46:34
then a couple of papers and.
1:46:36
I will include those on our
1:46:38
references page on our website.
1:46:40
I read through a number of fun
1:46:43
papers about the biology and
1:46:45
a few good ones on
1:46:47
the epidemiology. We'll post all of our sources
1:46:49
on our website. This podcast will kill You dot com.
1:46:51
Under the episodes tab, you can find
1:46:54
all of our sources for this and every single
1:46:56
one of our episodes.
1:46:59
Yeah yeah, thank
1:47:01
you to Bloodmobile for providing the music for
1:47:03
this episode and all of our episodes.
1:47:07
And thank you everyone for listening.
1:47:10
Yes, thank you.
1:47:11
We hope that you enjoyed this one as much
1:47:13
as we enjoyed talking about it.
1:47:16
We really enjoyed this one, so we hope that
1:47:18
you guys did too, So well
1:47:22
with that, until next time, wash
