Disease Discovery in Animals & Global Health | Mark Ackermann | TEDxGooseLake


just quickly what does a pathologist do

when we cut update animals and we also

take surgical biopsies from animals and

we read out diagnosis and we read out

the reasons why animals are you sick or

ab dermatitis or hepatitis whatever and

so long this is my son here and i sat by

lilly last night so I we had some of

those conversations that were just

fantastic and my wife she’s from

Bellevue and that’s our there so my talk

today is about animal health and

discovering animal health and it’s

interrelatedness to human disease in

global health and I’m going to talk

about domestic animals and exotic

animals somewhat so that’s that’s what

I’m going to talk about the health of

animals especially our domestic even

even some of our livestock animals and

how it’s interrelated to human in global

health and so as a veterinary

pathologist and a veteran at

veterinarian we’re well positioned to

see this because this we’re seeing

animals that die is apologist other

veterinarians are diagnosing disease but

we’re seeing the lesions histologically

microscopically that’s going on some of

these animal tissues that’s very similar

to what you see in human disease but

we’re at that point where we’re seeing

some stuff that maybe others don’t see

and there’s plenty of scientists that do

similar things and they have great ideas

also but there’s there’s a core that a

few core things in these examples that

I’ll talk about today and I bet that you

know most of these that I’m going to

talk about that anybody know where this

is by the way you probably do its

Bellevue like a damn number 12 and so

that’s Charlie fragments flatness he’s

from Mason said he’s a friend of mine

and he’s well positioned there to die

them to lock and dam number 12

Mississippi River and that’s that’s my

correlate of us being as veterinarians

be well positioned for diagnosis of

these diseases anybody know this guy

probably not I didn’t and so his name is

dr. Salman and he was from the first

veterinary class in the United States

well in the universe

canon is the oldest vendor school in our

Comerica but he was from the first met

in our class but dr. salman si el mo an

ring bell so Salman not the fish but

he’s important for one thing and

probably many other things too but he

was a guy that isolated salmonella and

salmonella is caused typhoid fever and

all that so he reckoned he was working

in microbiology and we recognize this

organism identified it and that organism

cause disease in a lot of different

species but it also causes disease in

humans also working in his lab is

Theobald Smith and Theobald Smith

identified in cultured brucellosis which

also causes these and animals that can

also cause in the cause disease in

humans as well so there’s an example of

somebody just kind of porphyrin kind of

working on things recognizing things

putting two and two together and

identified some things this one is Bill

have oh and Bill have Oh kind of looking

what I have there I have up on the

screen scrapie and kuru and you can see

a sheep and then right next to that is a

brain it’s a section of a brain and I’ve

met bill he’s a veterinarian he’s a

veterinary pathologist he passed away a

couple years ago wonderful humble you a

human being but in the 1950s he was some

working on scraping and scrape is a

disease it’s a CNS disease that’s its

kind of obscure and he was noticing that

the sheep and even talk eventually went

to work on mink encephalopathy and

chronic wasting disease and sheep but he

was noticing these things in chief and

he had read about this disease called

kuru in Guinea in New Guinea some of the

native people that live in New Guinea

and they had a ritual of eating at some

sort of ritual were they eat brains so

there’s some cannibalism and they

developed this deletion and it come to

find out that it was a prion disease

which we now know in these cruel people

or in this disease called kuru that is

actually similar to scrapie and sheep

and so he put that together and that

what I have out there that text up there

is a letter he sent to the

lancet the journal Lancet and he

connected these two things and

eventually people went on and said aha

yes they are connected and then then

further on then staniel prisoner he

identified prion ceased being the cause

of these and so unfortunately he didn’t

get the Nobel Prize everybody that

worked on that around him ended up

getting the Nobel Prize but he was the

one that connected it and came that

close to the Nobel Prize but don’t put

that connection get really interesting

story and humble is just our most humble

guy and so accomplished so then this one

this is dr. John clue be an island in

another veterinary pathologist and

you’ll see there’s some sections there

there’s a brain and then there’s another

brain on the right and then there’s a

cow that’s kind of stumbling around well

John Kluge was working about he was a

veteran pathologist in my part with my

current department and when he retired

he worked for an vsl national veterinary

services lab and their job is to look at

brains of cattle letter down to make

sure that we’re not getting bovine

spongiform encephalopathy in the united

states which is mad cow disease and mad

cow disease is a prion disease similar

bill had holes that just rape improve

thing that i was just talking about but

one Saturday John was looking in the

slides and we had never had BF c in the

United States and John was looking at

his slides 20 slides and number 18 was

red and he’s not that’s really odd you

know why is that red well he went

through one by one by one by one

negative negative deadly that red one he

thought he was an artifact no it was mad

cow so he called that the billion-dollar

diagnosis which has potentially funny

and real because then during that

weekend I think he diagnosed it on a

Saturday and then the stocks changed

immensely by monday and it probably

changed mcdonough stocks or whatever bye

dollars and since then we’ve had mad cow

we’ve had a few cattle that have had it

but you know we’re living with it were

understanding and diagnosing it better

it’s just not United States much anymore

but just another example of a person

putting a couple things together and the

effects that it has on on animal and

human in global health Tracy McNamara

she’s a veterinary pathologist I met

Tracy when she we were training at a

similar training session years ago and

then I want my way she went her way and

she was working at the Bronx Zoo in New

York and she noticed in 1999 some

there’s reports of horses dying and then

in New York City there are reports of

people dying and then a reports of crows

dying so I think this might be sounded

familiar to you and but she was at the

zoo and the cormorants are dying I can

hardly say that word but it’s a bird she

noticed the cormorants are dying and

Tracy was thinking could there be

something connected between the humans

the horse the crows the cormorants and

so she did a whole bunch of

investigation and a whole bunch of work

ends up West Nile virus that’s what it

was and she had that virus isolated from

the car- it was a flavivirus is what it

is had it isolated here at NV SL in Ames

Iowa and the CDC wouldn’t believe it

because lots of the bedroom lab we don’t

quite believe that it’s not quite

accurate and then she it’s fun to cook

listen to her talk but she ended up you

know cracking the case and that’s what

it ended up being small world I know her

and ends up that she’s going to talk to

our student pathology group on tuesday

she’s going to zoom in and do a zoom

with our student group so another

connection big impact West Nile still

around about 2010 where there’s a little

more higher incidence of it but now it’s

a little bit thin the backwater but it’s

just a neat thing and it shows the

interdependence again of some of these

diseases in our domestic

animals that affect global human health

but this is Nancy Jax and her husband

Jerry jacks they’re in the military and

so one picture of them is in the uniform

their Kansas State University Nancy’s a

veterinary pathologist Jerry is not a

veterinary pathologist into the

veterinarian but I just talked about

this one because in Reston Virginia a

fair number of years ago they are the

ones that there was an outbreak of Ebola

virus in Reston Virginia was in a

research lab and they’re in their suits

there they had to go in they did all

this brave work and then off an offshoot

was that was the book called outbreak

and then the movie was hot so on then

the hot zone came out so they work with

Ebola virus and then as you know a few

years ago that’s been out in in Africa

and it’s been spreading and now that’s

dad down a little bit too but anyway

those are two again veterinary

pathologist right on the cutting edge

veterinarians that see this and put well

that wasn’t putting two to do two

together that was working with the virus

itself and it was really neat they have

really need stories about what they did

the only thing I would add to that story

is that their veterinarians outbreak

came out but when the movie came out on

the hot zone they ended up changing him

from veterinarians to physicians I don’t

know why exactly but it’s just probably

something better they made a better

story I don’t know so I got a couple

more examples and this is a friend of

mine mark williamson and so he’s not an

eye when he’s an Australian actually but

he worked at Iowa State University

veterinary pathologist and he’s the one

on the low broad one and he’s with his

friend they did a swim meet in Australia

and they just got done and so on that’s

him there but mark worked on hendra

virus and in Australia there were some

horses dying again and people were

wondering why and it ends up that there

was these some flying foxes the bat

that’s shown there and the flying foxes

would rest on trees and then they’re

dropped they eat the fruit droppings had

come down the horses would eat through

the horse of the die but hendra virus is

a paramyxovirus and people were dying

too so they also worked with these

infectious agents they ended up stopping

it it didn’t

bread watch out of Australia and

probably never will because the flying

foxes are the kind of a unique niche but

it is one of those small connections

connections of a disease that affects

our domestic animals in some spread to

humans as well just kind of interesting

as well so now this is I’m gonna give an

example here I just have two more

examples and I’ll be doing but this is

not really an outbreak of things this is

cystic fibrosis people familiar with

cystic fibrosis it’s a devastating

disease of infants that’s being treated

better and better with time now the

infant song live a lot longer than they

used to but it’s a genetic defects and

they’re cftr receptor gene so they don’t

secrete chloride into the lungs and they

get a lot of ammonia is pretty easily

they also have some pancreatic

deficiencies there was a mouse model

this they knocked out that gene in mice

but the mice never had the respiratory

problem and that’s a big problem because

most individuals if they die they die of

the respiratory component more so than

pancreatic calls for operations and so

in the top I guess your top right is

Mike Welsch she’s an Iowan Paul McRae’s

from Davenport I when they’re both

physicians and in the middle center is

Dave Meyer Holtz and he’s a veterinary

pathologist from wapello he worked at

I’ve State University and those three

got together and they decided they were

going to make a cystic fibrosis pig and

they did and the pig has a respiratory

relations and the respiratory lesions

mimic that Memphis very well and so it’s

a huge breakthrough it’s a neat model

and now it’s used it so I think one of

the leading models for studying cystic

fibrosis and infants in this model and

things and so all islands here at the

University of Iowa a domestic animal

that we know really well and it’s it’s

important to our economy but they’ve

used that need to see a pig and it’s

just fantastic model and now they can

use it for therapies and valuable seen

on different disease conditions of

cystic fibrosis symptoms so now i’m near

to the end of my talk in this is me so

this is i’m up on that picnic table my

grandma and spray Pope took that picture

I don’t know how I didn’t fall off I had

these slick shoes on and I’m feeding

that little lamb but I work with lambs

now and i work with respiratory

syncytial virus people familiar with

that you’ve probably all had it and it

causes the common cold but in infants it

causes severe pneumonia and it causes

bronchiolitis and here again rsd doesn’t

have a great model oops cotton rat model

there’s a mouse model and it doesn’t

have it’s missing a lot of stuff and so

some of my work I’ve worked on

respiratory syncytial virus and lambs

which seems kind of odd but the neat

thing is this virus in human replicates

well in lands and I wasn’t the first to

start this land model some others

Randall couplet and hard lehmkuhl at the

national anthem of the sea center first

started working with bovine respiratory

syncytial virus and lambs and started

working on it and then marks Williamson

a guy from Australia came up to me one

time and said hey mark jammer I think

about working on RSV and putting that

human virus into lambs and said no and

so I did and now we’ve developed this

model a lot of work number of years but

now we’re using this model to test human

pharmaceuticals and I was at the

International RSV meeting in Argentina

last September and it’s looking like

there could be a drug for RSV and

probably the next five to ten years and

a couple of the drugs were working with

one is already in infants or adults and

going in infants and another one is in

humans and working well in humans and so

that’s a really heat operate or outcome

and it’s just working with this virus

strain again using one of our animal

models to study a human disease that has

a global impact because RSV is it’s not

only affects house here in the United

States but it could be devastated in

certain countries so then lastly there

like I said there’s many many other

people working on a lot of these

diseases that have global

pack I have this as the door of my

office in science magazines one of the I

guess highest-quality scientific

journals that there is science and

nature they’re very important you can

publish in science you’re doing really

well well I I collect those that have a

bomb some of our animals domestic

animals are wild animals here and they

don’t they’re cute most of them are cute

but that’s not why they’re on the cover

they’re on the cover because they have

some sort of paradigm shift or very very

significant impact on disease or basic

biology or basic medicine and I have

that there because it’s just another

indication of a global impact of some of

our animal models that affects health in

life of our biodiversity in India in the

world and also the health of humans in

the health of our animals in the

domestic and wild animals there’s a

number of offshoots from those and there

always will continue to be and we have

one planet and I think you have to keep

the help with this planet com safe and

secure and we need to just continually

learn about all these diseases in the

wide biodiversity yeah and that’s all I got thank you
