CWD ‒ Questions and Answers DEER
JULY 2016 - JUNE 2017 REGULATIONS SUMMARY 31
What is CWD — Chronic Wasting Disease?
CWD is a neurological (brain and nervous system) disease of deer and elk
known to occur in limited geographical locations in North America. The disease
belongs to a family of diseases known as transmissible spongiform encephalopathy
(TSE). These diseases are caused by an abnormal form of a protein called a
prion. In deer and elk there is no practical test of live animals to detect CWD,
and there is no known treatment or vaccine.
How is it spread?
It is thought that the most common mode of transmission from an infected
animal is via saliva, feces, urine and possibly other body secretions. The
infectious prion persists in the environment. There is evidence that people
moving live infected animals have spread the disease over long distances.
Is it dangerous to humans?
There currently is no convincing evidence that the agent of CWD affects
humans. However, public health officials recommend that human exposure to the
CWD agent be avoided as they continue to research the disease. This includes not
eating meat from known infected animals or animals that appear sick.
Where has it been found?
As of June 2016, CWD has been detected in free-ranging deer and elk in
portions of Arkansas, Colorado, Illinois, Iowa, Kansas, Maryland, Michigan,
Minnesota, Missouri, Nebraska, New Mexico, New York, North Dakota, Pennsylvania,
South Dakota, Texas, Utah, Virginia, West Virginia, Wisconsin, Wyoming, and
Alberta and Saskatchewan, Canada. In addition, CWD has been found in
captive/farmed elk and white-tailed deer in Colorado, Iowa, Kansas, Michigan,
Minnesota, Missouri, Montana, Nebraska, New York, Ohio, Oklahoma, Pennsylvania,
South Dakota, Texas, Wisconsin, and Alberta and Saskatchewan, Canada.
In West Virginia, CWD has been found in 195 white-tailed deer. Testing of
road-kill deer in all WV counties has been continuous since 2002. The WVDNR,
Wildlife Resources Section, in cooperation with various USDA certified
laboratories has tested over 15,700 deer from West Virginia for CWD and as of
June 2016, the 191 Hampshire County deer and four Hardy County deer are the only
animals found thus far to have the abnormal prion associated with CWD.
What is being done about CWD in WV?
CWD in West Virginia represents a significant threat to the state’s
white-tailed deer. The disease does not create an immediate widespread die-off
of deer, but if allowed to spread, will cause longterm damage to the herd. The
DNR is taking action to gather more information on the prevalence and
distribution of the disease in the area surrounding all known infected deer. The
DNR also discourages supplemental feeding and baiting of deer statewide, bans
these practices on public land for a portion of the year, and also bans these
practices anytime in Berkeley, Grant, Hampshire, Hardy, Jefferson, Mineral and
Morgan counties. In addition there are restrictions on the disposal and
transport of deer carcasses from Hampshire, Hardy, and Morgan counties within
the WV containment area (see WV CWD containment area) and portions of MD, PA and
VA where CWD has been detected. There are no proven solutions to combating CWD
once present in free-ranging deer. Thus, future management actions will be
adaptive and based on the findings of current and future surveillance. West
Virginia’s
Chronic Wasting Disease Containment Area
Includes all of Berkeley, Grant, Hampshire, Hardy, Jefferson, Mineral and
Morgan counties (cross hatch counties above). It is illegal to bait or feed deer
any time in the “Containment Area” (see baiting and feeding regulations on page
12). In addition, hunters are prohibited from transporting dead deer or their
parts beyond the boundary of Hampshire, Hardy, and Morgan counties (shaded
counties above) within the containment area except for the following: meat that
has been boned out, quarters or other portions of meat with no part of the
spinal column or head attached, cleaned hide with no head attached, clean skull
plate (no meat or tissue attached) with antlers attached, antlers with no meat
or tissue attached, and finished taxidermy mounts. Hunters may transport cervid
carcasses that were not killed inside the containment area through the
containment area.
What can hunters do?
• If you kill or observe a severely emaciated (very skinny) deer or a deer
that is obviously sick, or a deer with an ear tag, contact the WV DNR Wildlife
Resources Section office nearest you.
• Do not feed or bait deer. These practices concentrate deer, increase the
likelihood of spread of any disease present in the deer herd, and may introduce
foreign contaminates via the feed or bait.
• Harvest adequate numbers of antlerless deer to maintain deer populations
in balance with natural food supplies. A deer population in balance with
available habitat is healthier and less likely to spread diseases.
• Avoid using natural deer urine based lures in the environment and do not
place these urine lures on the ground or on vegetation where deer can reach
them.
• If you hunt deer or elk out of state bring back only boned out meat or
quarters and thoroughly cleaned skull plates and antlers. This applies to all
CWD-positive states, except for VA, MD, OH and PA where it applies only to the
state designated CWD containment area or CWD disease management areas.
• If you hunt in Hampshire, Hardy, or Morgan counties, see special
regulations regarding carcass transport and disposal. Also, please cooperate
with WVDNR requests for information and samples needed for CWD testing (see page
12 for testing locations).
• If you kill a cervid (deer, elk, etc.) out of state in a fenced enclosure
only boned out meat or quarters and thoroughly cleaned skull plates and antlers
may be transported into the state.
Efforts to monitor and control the spread of chronic wasting disease (CWD)
in free-ranging deer in Hampshire and Hardy counties by DNR, landowners and
hunters are ongoing. In the 2014 deer seasons, samples from 472 hunter-harvested
deer brought to game checking stations in Hampshire County, two stations in
northern Hardy County and one station in northern Morgan County were tested for
CWD. Nineteen samples were found to have the abnormal protein associated with
CWD. CWD has now been detected in 179 deer in Hampshire County and four deer in
Hardy County. Lowering encounter rates between infected and non-infected animals
by prohibiting artificial supplemental feeding and baiting are generally
accepted management practices for slowing the spread of an infectious disease
among wildlife and initiating these prohibitions on a statewide or regional
basis for deer is a major tool used by other states combating CWD. The
containment area for baiting and carcass transport has been expanded in 2015.
Questions and Answers – CWD 2014-2015 Hunting Regulations
In West Virginia, CWD has been found in 162 white-tailed deer. Testing of
road-kill deer in all WV counties has been continuous since 2002. The WVDNR,
Wildlife Resources Section, in cooperation with the SE Cooperative Wildlife
Disease Study at the University of Georgia and the Minnesota Veterinary
Diagnostic Laboratory, has tested more than 15,023 deer from West Virginia for
CWD and as of June 2014, the 159 Hampshire County deer and three Hardy County
deer are the only animals found thus far to have the abnormal prion associated
with CWD.

Chronic wasting disease spreads in West Virginia
Efforts to control the spread and monitor chronic wasting disease (CWD) in
free-ranging deer in Hampshire and Hardy counties by DNR, landowners and hunters
are ongoing. In the 2013 deer seasons, samples from 591 hunter-harvested deer
brought to game checking stations in Hampshire County, two stations in northern
Hardy County and one station in northern Morgan County, were tested for CWD.
Twenty-nine samples were found to have the abnormal protein associated with CWD.
CWD has now been detected in 159 deer in Hampshire County and three deer in
Hardy County. Lowering encounter rates between infected and non-infected animals
by prohibiting artificial supplemental feeding and baiting are generally
accepted management practices for slowing the spread of an infectious disease
among wildlife and initiating these prohibitions on a statewide or regional

Efforts to control the spread of chronic wasting disease (CWD) in
free-ranging deer in Hampshire County by DNR, landowners and hunters are
ongoing. In the 2012 deer seasons, samples from 672 hunter-harvested deer
brought to game checking stations in Hampshire County, two stations in northern
Hardy County and one station in northern Morgan County were tested for CWD.
Sixteen samples were found to have the abnormal protein associated with CWD. CWD
has now been detected in a total of 131 deer in Hampshire County and two deer in
Hardy County. Lowering encounter rates between infected and non-infected animals
by prohibiting artificial supplemental feeding and baiting are generally
accepted management practices for slowing the spread of an infectious disease
among wildlife and initiating these prohibitions on a statewide or regional

Chronic Wasting Disease (CWD), a transmissible spongiform encephalopathy of
cervids, was discovered in Hampshire County in September 2005. Efforts to
control the spread of chronic wasting disease (CWD) in free-ranging deer in
Hampshire County by DNR, landowners, and hunters are ongoing. During this report
period the abnormal prion associated with CWD was detected in 17 additional deer
in Hampshire County, nine of 1,134 hunter harvested deer tested positive, seven
deer collected in the spring of 2012 by WVDNR sharpshooters tested positive, and
one road kill deer tested positive. The abnormal prion associated with CWD has
now been found in 117 deer within West Virginia: three road-killed deer, four
deer collected by the DNR in 2005, five deer collected by the DNR in 2006, one
hunter-harvested deer during the 2006 deer season, three deer collected by the
DNR in 2007, six hunter-harvested deer during the 2007 deer season, 11 deer
collected by the DNR in 2008, six hunterharvested deer during the 2008 deer
season, nine deer collected by the DNR in 2009, 15 hunterharvested deer during
the 2009 deer season, 12 deer collected by WVDNR in 2010, 10 hunter-harvested
deer during the 2010 deer season, 16 deer collected by the WV DNR in 2011, nine
hunter-harvested deer during the 2011 deer season, and seven deer collected by
the WVDNR in 2012. One of the positive hunter-harvested deer from 2010 deer
season was from northern Hardy County. As of June 30, 2012, the prevalence of
CWD in a 39-square mile intensively monitored area in central Hampshire County
falls within a 95 percent confidence interval of nine to 22 percent. All tissue
samples during this report period were tested for the abnormal prion associated
with CWD at the SCWDS, College of Veterinary Medicine, The University of
Georgia, Athens, Georgia. Efforts to control the spread of CWD in freeranging
deer in Hampshire and Hardy counties by WVDNR, landowners, and hunters are
ongoing and the containment area currently includes all of Hampshire County,
northern Hardy County north of Corridor H and WV Route 55, and west of US Route
522 in Morgan County. More than 4,400 samples collected by the DNR since 2002
from principally road-killed deer in the remainder of the state have not
exhibited the abnormal prion of CWD in any county other than Hampshire and
northern Hardy County.
Chronic Wasting Disease (CWD), a transmissible spongiform encephalopathy
of cervids, was discovered in Hampshire County in September 2005. Efforts to
control the spread of CWD in free-ranging deer in Hampshire County by DNR,
landowners, and hunters are ongoing. In the 2009 deer seasons, samples from
1,091 hunter-harvested deer brought to game checking stations in Hampshire
County and one station in northern Hardy County were tested for CWD. Fourteen
samples were found to have the abnormal proteins associated with CWD. CWD now
has been detected in a total of 60 deer in Hampshire County, two road-killed
deer (one in 2005 and one in 2008), four deer collected by the DNR in 2005, five
deer collected by the DNR in 2006, one hunter-harvest deer taken during the 2006
deer season, three deer collected by the DNR in 2007, six hunter-harvested deer
taken during the 2007 deer season, 11 deer collected by the DNR in 2008, six
hunter-harvested deer taken during the 2008 deer season, eight deer collected by
the DNR in 2009 and 14 hunter-harvested deer taken during the 2009 deer season.
More than 4,200 samples collected by the DNR elsewhere in the state since 2002,
primarily from vehicle collisions, have not detected the abnormal protein of CWD
in any county other than Hampshire.

Chronic Wasting Disease (CWD), a transmissible spongiform encephalopathy
of cervids, was discovered in Hampshire County in September 2005. The Wildlife
Resources Section initiated a response plan to address the disease and conducted
extensive sampling efforts which have included 1,355 hunterharvested samples
tested for the disease in 2008. Five tests were positive for the disease
indicating the disease is not wide spread or is at a low prevalence. CWD has now
been detected in a total of 37 deer in Hampshire County: two vehicle-killed
deer, four deer collected by DNR in 2005, five deer collected by DNR in 2006,
one hunter-harvested deer during the 2006 deer season, three deer collected by
DNR in 2007, six hunter-harvested deer during the 2007 deer season, 11 deer
collected by DNR in 2008, and five hunter-harvested deer during the 2008 deer
season. More than 3,500 samples collected by the DNR elsewhere in the state
since 2002, primarily from vehicle collisions, have not detected the abnormal
protein of CWD in any county other than Hampshire. Management efforts to reduce
the prevalence and/or slow the rate of spread of the disease are
continuing.

Chronic Wasting Disease (CWD), a transmissible spongiform encephalopathy of
cervids, was discovered in Hampshire County in September 2005. The Wildlife
Resources Section initiated a response plan to address the disease and conducted
extensive sampling efforts that have included more than 4,300 tested for the
disease in three years of sampling. Only 31 of the tests were positive for the
disease, indicating the disease is not widespread or is at a low prevalence.
Management efforts to reduce the prevalence and/or slow the rate of spread of
the disease have been initiated.
During this past year Chronic Wasting Disease (CWD) was found in West
Virginia’s whitetail deer herd, which resulted in many man-hours of work in
conjunction with the DNR Wildlife Section personnel in sampling, monitoring and
educating the public to CWD.
Chronic Wasting Disease (CWD), a transmissible spongiform encephalopathy of
cervids, was discovered in Hampshire County in September 2005. The Wildlife
Resources Section initiated a response plan to address the disease and conducted
extensive sampling efforts which included 1,404 deer tested for the disease.
Only nine of the tests were positive for the disease, indicating the disease is
not wide spread nor is at a low prevalence. Management efforts to reduce the
prevalence and/or slow the rate of spread of the disease have been initiated.

Captive Cervid Farm in Wood County Reports Escape 11/25/2015
Page Content Charleston, W.Va. -- On Wednesday morning, November 25, 2015,
the owners of a private captive cervid farm in Wood County reported to the West
Virginia Department of Agriculture (WVDA) that 11 deer located within the
confines of their farming operation escaped from the facility.
As of 12 noon Wednesday eight of the escaped deer had been depopulated with
efforts to account for the other three continuing. Personnel from the WVDA were
immediately dispatched to the facility and will conduct Chronic Wasting Disease
(CWD) testing on the depopulated animals. The West Virginia Division of Natural
Resources (DNR) was notified by the WVDA and has also sent personnel to the
scene.
The owner of the farm told the WVDA that some bucks were fighting in the
area of a gate and the entrance was compromised. For further information or
questions contact Butch Antolini, WVDA Director of Communications and Marketing,
at 304-890-2945, or via email at bantolini@wvda.us

What a difference a year can make. Just 12 months ago, the deer farming
industry in West Virginia was more about regulations than opportunities. Mark
and Anita Cobb, who own a herd of red deer, weren’t sure what the future held
for their 36-acre family farm or the deer they treat like members of the
family.
The Cobbs started out with just one buck and two doe a decade ago. Their
herd grew to 27 before they culled it a few years back. At the time, deer
farming in West Virginia was uncertain.
“The paperwork was a nightmare,” explained Mark Cobb, who serves on the
Board of Directors for the North American Deer Farmers Association.
Under the WV Division of Natural Resources, deer farmers could only raise
animals to sell to hunting preserves or for breeding stock. Harvesting venison
for commercial sale was a no-go.
“People wanted the meat. We just couldn’t sell it,” said Cobb.
The main concern was Chronic Wasting Disease, or CWD, a fatal illness found
in deer that impacts the nervous system. In West Virginia, it’s only been
located in the wild whitetail population.
“CWD has never been found at one of our deer farms in West Virginia, not
one! We test every captive deer, 100 percent. We can positively say we have
never had CWD in our pens,” stressed Cobb.
The Cobbs took a couple years off from breeding to decide what direction
they wanted to go. Then the West Virginia Legislature passed a bill in 2015
making their path crystal clear. Deer farming moved from the control of the DNR
to the
West Virginia Department of Agriculture.
Marcel Fortin, the WVDA Captive Cervid Specialist, said the agency is
breaking ground.
“In most states, venison has not been the priority, it’s been deer hunting.
In West Virginia, we want to change that and diversify. We want to make deer
farms profitable,” explained Fortin. “We want farmers to be able to sell
venison. There’s potential for jobs!”
The Cobbs started doing their homework and getting the ball rolling on
venison sales.
“We’re trying to do two things with venison,” explained Cobb. “We’re
looking for restaurant customers and we’re putting together snack sticks that
can go on the shelves of every convenience store in the state.”
Currently most of the venison sold here in the United States is
imported.
“You can go to a nice restaurant in Philadelphia or Baltimore and find
venison on the menu. I try to talk to the chef at each establishment. Every time
I’ve found the venison has come from New Zealand! Ninety percent of the venison
consumed in the United States in a restaurant or grocery setting comes from New
Zealand.”
Cobb wants the meat to come from West Virginia. With the leadership of the
WVDA, he’s confident that can happen.
“We are leading the nation when it comes to deer farming,” said West
Virginia Commissioner of Agriculture Walt Helmick. “We want to create a thriving
industry that benefits the farmers and the purchasing public. We want West
Virginia-grown venison to be served all across the country.”
The Cobbs only have 12 red deer on their farm in Jackson County. They plan
to start breeding again but it will take several years to increase the herd.
They don’t want to wait that long to get their venison business up and running.
West Virginia currently has 31 licensed deer farms, including three hunting
preserves. None of the breeding farms have the quantity of deer Cobb needs to
start production. He had to look outside the state.
“We’ve reached out mostly to the Amish community in Ohio. I’m friends with
those folks,” said Cobb. “I contacted them and said, ‘I’ll take your cull deer.’
My phone is ringing off the hook. I’m up to 450-some doe. They’re just waiting
for us to come pick them up.”
Ohio and neighboring Pennsylvania do not allow the sale of venison from
captive deer. Cobb said those farmers are dealing with the issue of what to do
with doe that aren’t good breeding stock. With his need for venison, it’s a
win/win.
“Because this is so new, we have to figure out the process. We’re working
with the WVDA and we’ve found a place to butcher and process the animals here in
West Virginia. First, they have to make some changes to the plant to meet our
needs.”
Cobb also wants to make sure he has the customer base to make his business
profitable.
“It doesn’t do me any good to take 20 deer to be processed and wrapped but
have nowhere to sell it. We’re trying to build a clientele base.”
The Cobb’s got their first order in December for burgers and steaks from a
restaurant in West Virginia. The Greenbrier Resort has also called, interested
in a future purchase.
“There are a lot of people excited about what we’re doing. However, there
are unknowns. It’s going to take a while to get some traction,” stressed Cobb.
Bob Perrine, the owner of Mountain Clean Whitetails, is also pleased with the
changes taking place with deer farming in West Virginia. His operation in Lewis
County includes 79 whitetails. He raises the animals for breeding stock or sale
to hunting preserves. His most popular buck is a 3-year-old with a 300-inch
rack.
“Popeye is pretty well known in West Virginia. We have a Facebook account
and the last video we posted of him was viewed by 7,000 people within a day or
two,” Perrine said proudly.
Popeye’s two offspring, Moonshine and Hidden Highway, already span 200-plus
inches. But it’s not just racks Perrine is thinking about. He believes the
future of his business is in venison as well.
“At this point we’re just a breeding facility. This summer and next we’re
planning on more than doubling our farm operation to 300 deer. We want to expand
to do meat processing right here on the farm.” The first order of business is
expanding the fences from 25 acres to 50 and then breeding and purchasing more
animals.
“I’ve talked to several people in this industry. People want the product.
We just have to get things up and going,” said Perrine.
That will mean building their own processing facility. By the time Perrine
is ready to start construction, the Cobbs should have their operation in full
production. Mark Cobb feels he has a responsibility to create a business
blueprint others, like Perrine, can follow. “The infrastructure isn’t there
right now. We’re creating it. Each step we’re figuring out from scratch because
no one has ever done it here in West Virginia. We’re forging the way for
everyone else that wants to do it,” Cobb stressed. “We will have a tried and
true process and be able to tell other deer farmers what you have to do and this
is how you need to do it.” The Cobbs are currently working on some products for
the future line like venison dog snacks using the heart and liver. We don’t add
anything, just run them through a dehydrator. Friends are coming back to me
saying their dogs love it! I’ve tried it. People can eat it. I’m not going to
give a product to someone that I haven’t tested first.”
The Cobbs want to get their products on the shelves and in restaurants as
soon as possible, but there’s no set date. They say leading the herd takes time.
”The occurrence of CWD must be viewed against the contest of the locations
in which it occurred. It was an incidental and unwelcome complication of the
respective wildlife research programmes. Despite it’s subsequent recognition as
a new disease of cervids, therefore justifying direct investigation, no specific
research funding was forthcoming. The USDA veiwed it as a wildlife problem and
consequently not their province!” page 26.

Chronic wasting disease in a Wisconsin white-tailed deer farm

Gidlewski, Katherine I. O’Rourke, Terry R. Spraker, Michael D. Samuel
Abstract.
In September 2002, chronic wasting disease (CWD), a prion disorder of
captive and wild cervids, was diagnosed in a white-tailed deer (Odocoileus
virginianus) from a captive farm in Wisconsin. The facility was subsequently
quarantined, and in January 2006 the remaining 76 deer were depopulated. Sixty
animals (79%) were found to be positive by immunohistochemical staining for the
abnormal prion protein (PrPCWD) in at least one tissue; the prevalence of
positive staining was high even in young deer. Although none of the deer
displayed clinical signs suggestive of CWD at depopulation, 49 deer had
considerable accumulation of the abnormal prion in the medulla at the level of
the obex. Extraneural accumulation of the abnormal protein was observed in 59
deer, with accumulation in the retropharyngeal lymph node in 58 of 59 (98%), in
the tonsil in 56 of 59 (95%), and in the rectal mucosal lymphoid tissue in 48 of
58 (83%). The retina was positive in 4 deer, all with marked accumulation of
prion in the obex. One deer was considered positive for PrPCWD in the brain but
not in the extraneural tissue, a novel observation in white-tailed deer. The
infection rate in captive deer was 20- fold higher than in wild deer. Although
weakly related to infection rates in extraneural tissues, prion genotype was
strongly linked to progression of prion accumulation in the obex. Antemortem
testing by biopsy of recto– anal mucosal-associated lymphoid tissue (or other
peripheral lymphoid tissue) may be a useful adjunct to tonsil biopsy for
surveillance in captive herds at risk for CWD infection.

The State of Wisconsin paid nearly $300,000 to the Eau Claire County farmer
whose deer herd was depopulated after it was found to be infected with chronic
wasting disease.
Rick Vojtik, owner of Fairchild Whitetails in Fairchild, received an
indemnity payment of $298,770 for 228 white-tailed deer killed on his farm,
according to officials with the Department of Agriculture, Trade and Consumer
Protection.
The money was taken from the agency's general program revenue funded by
Wisconsin taxpayers.

*** TEST RESULTS FROM CAPTIVE DEER HERD WITH CHRONIC WASTING DISEASE
RELEASED 79.8 percent of the deer tested positive for the disease
DES MOINES – The Iowa Department of Agriculture and Land Stewardship today
announced that the test results from the depopulation of a quarantined captive
deer herd in north-central Iowa showed that 284 of the 356 deer, or 79.8% of the
herd, tested positive for Chronic Wasting Disease (CWD).
*** see history of this CWD blunder here ;
On June 5, 2013, DNR conducted a fence inspection, after gaining approval
from surrounding landowners, and confirmed that the fenced had been cut or
removed in at least four separate locations; that the fence had degraded and was
failing to maintain the enclosure around the Quarantined Premises in at least
one area; that at least three gates had been opened;and that deer tracks were
visible in and around one of the open areas in the sand on both sides of the
fence, evidencing movement of deer into the Quarantined Premises.

*** How Did CWD Get Way Down In Medina County, Texas?
DISCUSSION
Observations of natural outbreaks of scrapie indicated that the disease
spread from flock to flock by the movement of infected, but apparently normal,
sheep which were incubating the disease.
There was no evidence that the disease spread to adjacent flocks in the
absent of such movements or that vectors or other host species were involved in
the spread of scrapie to sheep or goats; however, these possibilities should be
kept open...

The Animal & Plant Health Agency became aware of the event on 5 April
2016, and alerted Defra. DEFRA published in March 2016 a revised assessment of
the risk of CWD to Great Britain. The revised assessment includes evaluation of
the risks posed by importation of deer urine lures from North America to the UK,
following the B.D.S survey on use of urine lures by stakeholders, see;
DEFRA published a Preliminary Outbreak Assessment on Cervid Spongiform
Encephalopathy in Norway on 7/4/16.
At present, there remain many unknowns with respect to the Norwegian
case:
• The origin of the prion is not known. Prions are transmissible between
individuals within a species, and some are transmissible between species.
However, they can also arise spontaneously. It is not yet possible to conclude
whether this prion was imported into Norway or arose there independently.
• It is not clear which prion has caused the disease in this reindeer.
Scrapie in sheep and goats, BSE in cattle, FSE in cats, TME in mink, CWD in
cervids and CJD in humans are all caused by prions. It is not possible
clinically to distinguish between TSEs caused by prions from different sources
(e.g. CWD and BSE) within the same species.
It is not clear whether this is a single case or is indicative of wider
infection in the herd. However the Norwegian Veterinary Institute is continuing
its routine surveillance, which detected this case.
The British Deer Society has been monitoring CWD in North America and has
established connections throughout the scientific world on this topic, the
Society is well informed and well connected, it will bring news on this event to
you as soon as it is available, meantime we propose that we should all maintain
our duty of care, and responsibilities if travelling around the world by being
as hygienic as possible with our outdoor clothes and footwear and by minimising
traffic in un-proven disease free animals or their body parts.
John Bruce The British Deer Society 07/04/2016.
Chronic Wasting Disease in Deer The British Deer Society has launched a new
leaflet aimed at hunters and sporting agents containing important
recommendations to prevent the spread of Chronic Wasting Disease (CWD).
The updated advice replaces previous guidance and follows an increase in
risk level to the UK with the announcement of three cases of the disease in
Norway. CWD has previously mainly been found in North America. Sporting agents,
hosts and guides are urged to make sure all guests to the UK are aware of the
risks and take steps to ensure that their equipment is suitably clean to
minimise the risk of spreading the disease. All those visiting areas at risk of
infection, especially for hunting purposes, must appreciate that it is almost
impossible to thoroughly sterilise potentially contaminated kit and clothing so
are strongly encouraged to consider leaving behind or disposing of what cannot
be completely sanitised.

BDS Campaigning Chronic Wasting Disease (CWD) is highly infectious and has
devastating effects on both wild and farmed deer. BDS is campaigning hard, along
with other organisations, to keep CWD out of the UK by promoting awareness of
the issue at border control points.
We encourage visitors to the UK to be vigilant about the cleanliness and
biosecurity of outdoor equipment. While the highest risks appears to be with
those engaged in sporting shooting, anyone hiking or camping in infected areas
has the potential to bring back infection on dirty boots, clothes or equipment.
CWD in Norway A Spongiform Encephalopathy, referred to as Chronic Wasting
Disease or CWD, was diagnosed in a free-ranging reindeer from southern Norway in
March 2016 by the Norwegian Veterinary Institute who are monitoring the reindeer
herd.
Please see below for regular updates on this issue.
14/06/2016 - Norway reports a third case Norway reports the diagnosis of a
third case, a second moose, (moose f2), a pregnant cow found in a river near to
moose f1, also confirmed TSE. Scientists have, for scientific reasons, named
these initial cases in Norway as “Cervid Wasting Disease” as they are the first
cases in a new species, one hopes that the use of multiple names does not cause
confusion, they are all TSE.
09/06/2016 – New DEFRA Publication - Cervid Spongiform Encephalopathy in
Norway The report looks at the coincidences of these two cases in different
species 450 km apart in Norway but finds no correlation nor evidence of
connection. The report states that Norway will implement a ban on the trade of
live cervids, which will include exportation; which is a relief.
25/05/2016 - The Norwegian Veterinary Institute report The Norwegian
Veterinary Institute reports that Chronic Wasting Disease had been diagnosed by
two different tests (ELISA and Western Blot) in a young adult, pregnant, female
moose. The moose had shown abnormal behaviour and was in poor bodily condition.
The moose comes from a different area (Selbu municipality in Sør-Trøndelag,
close to the Swedish border ) than the CWD case in the reindeer reported in
Norway in April this year. The initial speculation that the case in the reindeer
could have been a sporadic prion disease was ruled out by the confirmation of
CWD by the OIE reference lab in Canada. This is the second case of CWD
demonstrated in Europe and the first in moose. It is very unfortunate and
worrying and will certainly have huge consequences for hunting, surveillance and
management.

Chronic wasting disease (CWD) is a widespread and highly transmissible
prion disease in free-ranging and captive cervid species in North America. The
zoonotic potential of CWD prions is a serious public health concern, but the
susceptibility of human CNS and peripheral organs to CWD prions remains largely
unresolved. We reported earlier that peripheral and CNS infections were detected
in transgenic mice expressing human PrP129M or PrP129V. Here we will present an
update on this project, including evidence for strain dependence and influence
of cervid PrP polymorphisms on CWD zoonosis as well as the characteristics of
experimental human CWD prions.

Cervid to human prion transmission
Kong, Qingzhong
Case Western Reserve University, Cleveland, OH, United States
Abstract
Prion disease is transmissible and invariably fatal. Chronic wasting
disease (CWD) is the prion disease affecting deer, elk and moose, and it is a
widespread and expanding epidemic affecting 22 US States and 2 Canadian
provinces so far. CWD poses the most serious zoonotic prion transmission risks
in North America because of huge venison consumption (>6 million deer/elk
hunted and consumed annually in the USA alone), significant prion infectivity in
muscles and other tissues/fluids from CWD-affected cervids, and usually high
levels of individual exposure to CWD resulting from consumption of the affected
animal among often just family and friends. However, we still do not know
whether CWD prions can infect humans in the brain or peripheral tissues or
whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no
essays to reliably detect CWD infection in humans. We hypothesize that:
(1) The classic CWD prion strain can infect humans at low levels in the
brain and peripheral lymphoid tissues;
(2) The cervid-to-human transmission barrier is dependent on the cervid
prion strain and influenced by the host (human) prion protein (PrP) primary
sequence;
(3) Reliable essays can be established to detect CWD infection in
humans;and
(4) CWD transmission to humans has already occurred. We will test these
hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in
vitro approaches.
Aim 1 will prove that the classical CWD strain may infect humans in brain
or peripheral lymphoid tissues at low levels by conducting systemic bioassays in
a set of "humanized" Tg mouse lines expressing common human PrP variants using a
number of CWD isolates at varying doses and routes. Experimental "human CWD"
samples will also be generated for Aim 3.
Aim 2 will test the hypothesis that the cervid-to-human prion transmission
barrier is dependent on prion strain and influenced by the host (human) PrP
sequence by examining and comparing the transmission efficiency and phenotypes
of several atypical/unusual CWD isolates/strains as well as a few prion strains
from other species that have adapted to cervid PrP sequence, utilizing the same
panel of humanized Tg mouse lines as in Aim 1.
Aim 3 will establish reliable essays for detection and surveillance of CWD
infection in humans by examining in details the clinical, pathological,
biochemical and in vitro seeding properties of existing and future experimental
"human CWD" samples generated from Aims 1-2 and compare them with those of
common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.
Aim 4 will attempt to detect clinical CWD-affected human cases by examining
a significant number of brain samples from prion-affected human subjects in the
USA and Canada who have consumed venison from CWD-endemic areas utilizing the
criteria and essays established in Aim 3. The findings from this proposal will
greatly advance our understandings on the potential and characteristics of
cervid prion transmission in humans, establish reliable essays for CWD zoonosis
and potentially discover the first case(s) of CWD infection in humans.
Public Health Relevance There are significant and increasing human exposure
to cervid prions because chronic wasting disease (CWD, a widespread and highly
infectious prion disease among deer and elk in North America) continues
spreading and consumption of venison remains popular, but our understanding on
cervid-to-human prion transmission is still very limited, raising public health
concerns. This proposal aims to define the zoonotic risks of cervid prions and
set up and apply essays to detect CWD zoonosis using mouse models and in vitro
methods. The findings will greatly expand our knowledge on the potentials and
characteristics of cervid prion transmission in humans, establish reliable
essays for such infections and may discover the first case(s) of CWD infection
in humans.

Key Molecular Mechanisms of TSEs
Zabel, Mark D.
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Prion diseases, or transmissible spongiform encephalopathies (TSEs),
are fatal neurodegenerative diseases affecting humans, cervids, bovids, and
ovids. The absolute requirement of PrPC expression to generate prion diseases
and the lack of instructional nucleic acid define prions as unique infectious
agents. Prions exhibit species-specific tropism, inferring that unique prion
strains exist that preferentially infct certain host species and confront
transmission barriers to heterologous host species. However, transmission
barriers are not absolute. Scientific consensus agrees that the sheep TSE
scrapie probably breached the transmission barrier to cattle causing bovine
spongiform encephalopathy that subsequently breached the human transmission
barrier and likely caused several hundred deaths by a new-variant form of the
human TSE Creutzfeldt-Jakob disease in the UK and Europe. The impact to human
health, emotion and economies can still be felt in areas like farming, blood and
organ donations and the threat of a latent TSE epidemic. This precedent raises
the real possibility of other TSEs, like chronic wasting disease of cervids,
overcoming similar human transmission barriers. A groundbreaking discovery made
last year revealed that mice infected with heterologous prion strains facing
significant transmission barriers replicated prions far more readily in spleens
than brains6. Furthermore, these splenic prions exhibited weakened transmission
barriers and expanded host ranges compared to neurogenic prions. These data
question conventional wisdom of avoiding neural tissue to avoid prion
xenotransmission, when more promiscuous prions may lurk in extraneural tissues.
Data derived from work previously funded by NIH demonstrate that Complement
receptors CD21/35 bind prions and high density PrPC and differentially impact
prion disease depending on the prion isolate or strain used. Recent advances in
live animal and whole organ imaging have led us to generate preliminary data to
support novel, innovative approaches to assessing prion capture and transport.
We plan to test our unifying hypothesis for this proposal that CD21/35 control
the processes of peripheral prion capture, transport, strain selection and
xenotransmission in the following specific aims.
1. Assess the role of CD21/35 in splenic prion strain selection and host
range expansion.
2. Determine whether CD21/35 and C1q differentially bind distinct prion
strains
3. Monitor the effects of CD21/35 on prion trafficking in real time and
space
4. Assess the role of CD21/35 in incunabular prion trafficking
Public Health Relevance Transmissible spongiform encephalopathies, or prion
diseases, are devastating illnesses that greatly impact public health,
agriculture and wildlife in North America and around the world. The impact to
human health, emotion and economies can still be felt in areas like farming,
blood and organ donations and the threat of a latent TSE epidemic. This
precedent raises the real possibility of other TSEs, like chronic wasting
disease (CWD) of cervids, overcoming similar human transmission barriers. Early
this year Canada reported its first case of BSE in over a decade audits first
case of CWD in farmed elk in three years, underscoring the need for continued
vigilance and research. Identifying mechanisms of transmission and zoonoses
remains an extremely important and intense area of research that will benefit
human and other animal populations.

PMCA Detection of CWD Infection in Cervid and Non-Cervid Species
Hoover, Edward Arthur
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Chronic wasting disease (CWD) of deer and elk is an emerging highly
transmissible prion disease now recognized in 18 States, 2 Canadian provinces,
and Korea. We have shown that Infected deer harbor and shed high levels of
infectious prions in saliva, blood, urine, and feces, and in the tissues
generating those body fluids and excreta, thereby leading to facile transmission
by direct contact and environmental contamination. We have also shown that CWD
can infect some non-cervid species, thus the potential risk CWD represents to
domestic animal species and to humans remains unknown. Whether prions borne in
blood, saliva, nasal fluids, milk, or excreta are generated or modified in the
proximate peripheral tissue sites, may differ in subtle ways from those
generated in brain, or may be adapted for mucosal infection remain open
questions. The increasing parallels in the pathogenesis between prion diseases
and human neurodegenerative conditions, such as Alzheimer's and Parkinson's
diseases, add relevance to CWD as a transmissible protein misfolding disease.
The overall goal of this work is to elucidate the process of CWD prion
transmission from mucosal secretory and excretory tissue sites by addressing
these questions: (a) What are the kinetics and magnitude of CWD prion shedding
post-exposure? (b) Are excreted prions biochemically distinct, or not, from
those in the CNS? (c) Are peripheral epithelial or CNS tissues, or both, the
source of excreted prions? and (d) Are excreted prions adapted for horizontal
transmission via natural/trans-mucosal routes? The specific aims of this
proposal are: (1) To determine the onset and consistency of CWD prion shedding
in deer and cervidized mice; (2); To compare the biochemical and biophysical
properties of excretory vs. CNS prions; (3) To determine the capacity of
peripheral tissues to support replication of CWD prions; (4) To determine the
protease- sensitive infectious fraction of excreted vs. CNS prions; and (5) To
compare the mucosal infectivity of excretory vs. CNS prions. Understanding the
mechanisms that enable efficient prion dissemination and shedding will help
elucidate how horizontally transmissible prions evolve and succeed, and is the
basis of this proposal. Understanding how infectious misfolded proteins (prions)
are generated, trafficked, shed, and transmitted will aid in preventing,
treating, and managing the risks associated with these agents and the diseases
they cause.
Public Health Relevance Chronic wasting disease (CWD) of deer and elk is an
emergent highly transmissible prion disease now recognized throughout the USA as
well as in Canada and Korea. We have shown that infected deer harbor and shed
high levels of infectious prions in saliva, blood, urine, and feces thereby
leading to transmission by direct contact and environmental contamination. In
that our studies have also shown that CWD can infect some non-cervid species,
the potential risk CWD may represents to domestic animal species and humans
remains unknown. The increasing parallels in the development of major human
neurodegenerative conditions, such as Alzheimer's and Parkinson's diseases, and
prion diseases add relevance to CWD as a model of a transmissible protein
misfolding disease. Understanding how infectious misfolded proteins (prions) are
generated and transmitted will aid in interrupting, treating, and managing the
risks associated with these agents and the diseases they cause.

*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
***********CJD REPORT 1994 increased risk for consumption of veal and
venison and lamb***********
CREUTZFELDT JAKOB DISEASE SURVEILLANCE IN THE UNITED KINGDOM THIRD ANNUAL
REPORT AUGUST 1994
Consumption of venison and veal was much less widespread among both cases
and controls. For both of these meats there was evidence of a trend with
increasing frequency of consumption being associated with increasing risk of
CJD. (not nvCJD, but sporadic CJD...tss)
These associations were largely unchanged when attention was restricted to
pairs with data obtained from relatives. ...
Table 9 presents the results of an analysis of these data.
There is STRONG evidence of an association between ‘’regular’’ veal eating
and risk of CJD (p = .0.01).
Individuals reported to eat veal on average at least once a year appear to
be at 13 TIMES THE RISK of individuals who have never eaten veal.
There is, however, a very wide confidence interval around this estimate.
There is no strong evidence that eating veal less than once per year is
associated with increased risk of CJD (p = 0.51).
The association between venison eating and risk of CJD shows similar
pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK
OF CJD (p = 0.04).
There is some evidence that risk of CJD INCREASES WITH INCREASING FREQUENCY
OF LAMB EATING (p = 0.02).
The evidence for such an association between beef eating and CJD is weaker
(p = 0.14). When only controls for whom a relative was interviewed are included,
this evidence becomes a little STRONGER (p = 0.08).
snip...
It was found that when veal was included in the model with another
exposure, the association between veal and CJD remained statistically
significant (p = < 0.05 for all exposures), while the other exposures ceased
to be statistically significant (p = > 0.05).
snip...
In conclusion, an analysis of dietary histories revealed statistical
associations between various meats/animal products and INCREASED RISK OF CJD.
When some account was taken of possible confounding, the association between
VEAL EATING AND RISK OF CJD EMERGED AS THE STRONGEST OF THESE ASSOCIATIONS
STATISTICALLY. ...
snip...
In the study in the USA, a range of foodstuffs were associated with an
increased risk of CJD, including liver consumption which was associated with an
apparent SIX-FOLD INCREASE IN THE RISK OF CJD. By comparing the data from 3
studies in relation to this particular dietary factor, the risk of liver
consumption became non-significant with an odds ratio of 1.2 (PERSONAL
COMMUNICATION, PROFESSOR A. HOFMAN. ERASMUS UNIVERSITY, ROTTERDAM). (???...TSS)

Dear Mr Elmhirst,
CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT
Thank you for your recent letter concerning the publication of the third
annual report from the CJD Surveillance Unit. I am sorry that you are
dissatisfied with the way in which this report was published.
The Surveillance Unit is a completely independant outside body and the
Department of Health is committed to publishing their reports as soon as they
become available. In the circumstances it is not the practice to circulate the
report for comment since the findings of the report would not be amended. In
future we can ensure that the British Deer Farmers Association receives a copy
of the report in advance of publication.
The Chief Medical Officer has undertaken to keep the public fully informed
of the results of any research in respect of CJD. This report was entirely the
work of the unit and was produced completely independantly of the the
Department.
The statistical results reqarding the consumption of venison was put into
perspective in the body of the report and was not mentioned at all in the press
release. Media attention regarding this report was low key but gave a realistic
presentation of the statistical findings of the Unit. This approach to
publication was successful in that consumption of venison was highlighted only
once by the media ie. in the News at one television proqramme.
I believe that a further statement about the report, or indeed statistical
links between CJD and consumption of venison, would increase, and quite possibly
give damaging credence, to the whole issue. From the low key media reports of
which I am aware it seems unlikely that venison consumption will suffer
adversely, if at all.

Dear Sir/Madam,
In the Archives of Neurology you quoted (the abstract of which was attached

assumption would be wrong. I encourage you to read the whole article and call me
if you have questions or need more clarification (phone: 404-639-3091). Also, we
do not claim that "no-one has ever been infected with prion disease from eating

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated
bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD)
disease in human. To date, BSE agent is the only recognized zoonotic prion.
Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that
have been circulating for centuries in farmed ruminants there is no apparent
epidemiological link between exposure to ruminant products and the occurrence of
other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD).
However, the zoonotic potential of the diversity of circulating TSE agents has
never been systematically assessed. The major issue in experimental assessment
of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the
biological phenomenon that limits TSE agents’ propagation from a species to
another. In the last decade, mice genetically engineered to express normal forms
of the human prion protein has proved essential in studying human prions
pathogenesis and modeling the capacity of TSEs to cross the human species
barrier.
To assess the zoonotic potential of prions circulating in farmed ruminants,
we study their transmission ability in transgenic mice expressing human PrPC
(HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC
(129Met or 129Val) are used to determine the role of the Met129Val dimorphism in
susceptibility/resistance to the different agents.
These transmission experiments confirm the ability of BSE prions to
propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be
susceptible to BSE in sheep or goat to a greater degree than the BSE agent in
cattle and that these agents can convey molecular properties and
neuropathological indistinguishable from vCJD. However homozygous 129V mice are
resistant to all tested BSE derived prions independently of the originating
species suggesting a higher transmission barrier for 129V-PrP variant.
Transmission data also revealed that several scrapie prions propagate in
HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the
efficiency of transmission at primary passage was low, subsequent passages
resulted in a highly virulent prion disease in both Met129 and Val129 mice.
Transmission of the different scrapie isolates in these mice leads to the
emergence of prion strain phenotypes that showed similar characteristics to
those displayed by MM1 or VV2 sCJD prion. These results demonstrate that scrapie
prions have a zoonotic potential and raise new questions about the possible link
between animal and human prions.

Abstract
Classical bovine spongiform encephalopathy (c-BSE) is the only animal prion
disease reputed to be zoonotic, causing variant Creutzfeldt-Jakob disease (vCJD)
in humans and having guided protective measures for animal and human health
against animal prion diseases. Recently, partial transmissions to humanized mice
showed that the zoonotic potential of scrapie might be similar to c-BSE. We here
report the direct transmission of a natural classical scrapie isolate to
cynomolgus macaque, a highly relevant model for human prion diseases, after a
10-year silent incubation period, with features similar to those reported for
human cases of sporadic CJD. Scrapie is thus actually transmissible to primates
with incubation periods compatible with their life expectancy, although fourfold
longer than BSE. Long-term experimental transmission studies are necessary to
better assess the zoonotic potential of other prion diseases with high
prevalence, notably Chronic Wasting Disease of deer and elk and atypical/Nor98
scrapie.
snip...
In addition to previous studies on scrapie transmission to primate1,8,9 and
the recently published study on transgenic humanized mice13, our results
constitute new evidence for recommending that the potential risk of scrapie for
human health should not be dismissed. Indeed, human PrP transgenic mice and
primates are the most relevant models for investigating the human transmission
barrier. To what extent such models are informative for measuring the zoonotic
potential of an animal TSE under field exposure conditions is unknown. During
the past decades, many protective measures have been successfully implemented to
protect cattle from the spread of c-BSE, and some of these measures have been
extended to sheep and goats to protect from scrapie according to the principle
of precaution. Since cases of c-BSE have greatly reduced in number, those
protective measures are currently being challenged and relaxed in the absence of
other known zoonotic animal prion disease. We recommend that risk managers
should be aware of the long term potential risk to human health of at least
certain scrapie isolates, notably for lymphotropic strains like the classical
scrapie strain used in the current study. Relatively high amounts of infectivity
in peripheral lymphoid organs in animals infected with these strains could lead
to contamination of food products produced for human consumption. Efforts should
also be maintained to further assess the zoonotic potential of other animal
prion strains in long-term studies, notably lymphotropic strains with high
prevalence like CWD, which is spreading across North America, and atypical/Nor98
scrapie (Nor98)50 that was first detected in the past two decades and now
represents approximately half of all reported cases of prion diseases in small
ruminants worldwide, including territories previously considered as scrapie
free. Even if the prevailing view is that sporadic CJD is due to the spontaneous
formation of CJD prions, it remains possible that its apparent sporadic nature
may, at least in part, result from our limited capacity to identify an
environmental origin.
***Moreover, sporadic disease has never been observed in breeding colonies
or primate research laboratories, most notably among hundreds of animals over
several decades of study at the National Institutes of Health25, and in nearly

Prion diseases (PD) are the unique neurodegenerative proteinopathies
reputed to be transmissible under field conditions since decades. The
transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that
an animal PD might be zoonotic under appropriate conditions. Contrarily, in the
absence of obvious (epidemiological or experimental) elements supporting a
transmission or genetic predispositions, PD, like the other proteinopathies, are
reputed to occur spontaneously (atpical animal prion strains, sporadic CJD
summing 80% of human prion cases). Non-human primate models provided the first
evidences supporting the transmissibiity of human prion strains and the zoonotic
potential of BSE. Among them, cynomolgus macaques brought major information for
BSE risk assessment for human health (Chen, 2014), according to their
phylogenetic proximity to humans and extended lifetime. We used this model to
assess the zoonotic potential of other animal PD from bovine, ovine and cervid
origins even after very long silent incubation periods.
*** We recently observed the direct transmission of a natural classical
scrapie isolate to macaque after a 10-year silent incubation period,

Using in vitro prion replication for high sensitive detection of prions and
prionlike proteins and for understanding mechanisms of transmission.

Prion and prion-like proteins are misfolded protein aggregates with the
ability to selfpropagate to spread disease between cells, organs and in some
cases across individuals. I n T r a n s m i s s i b l e s p o n g i f o r m
encephalopathies (TSEs), prions are mostly composed by a misfolded form of the
prion protein (PrPSc), which propagates by transmitting its misfolding to the
normal prion protein (PrPC). The availability of a procedure to replicate prions
in the laboratory may be important to study the mechanism of prion and
prion-like spreading and to develop high sensitive detection of small quantities
of misfolded proteins in biological fluids, tissues and environmental samples.
Protein Misfolding Cyclic Amplification (PMCA) is a simple, fast and efficient
methodology to mimic prion replication in the test tube. PMCA is a platform
technology that may enable amplification of any prion-like misfolded protein
aggregating through a seeding/nucleation process. In TSEs, PMCA is able to
detect the equivalent of one single molecule of infectious PrPSc and propagate
prions that maintain high infectivity, strain properties and species
specificity. Using PMCA we have been able to detect PrPSc in blood and urine of
experimentally infected animals and humans affected by vCJD with high
sensitivity and specificity. Recently, we have expanded the principles of PMCA
to amplify amyloid-beta (Aβ) and alphasynuclein (α-syn) aggregates implicated in
Alzheimer's and Parkinson's diseases, respectively. Experiments are ongoing to
study the utility of this technology to detect Aβ and α-syn aggregates in
samples of CSF and blood from patients affected by these diseases.
=========================
***Recently, we have been using PMCA to study the role of environmental
prion contamination on the horizontal spreading of TSEs. These experiments have
focused on the study of the interaction of prions with plants and
environmentally relevant surfaces. Our results show that plants (both leaves and
roots) bind tightly to prions present in brain extracts and excreta (urine and
feces) and retain even small quantities of PrPSc for long periods of time.
Strikingly, ingestion of prioncontaminated leaves and roots produced disease
with a 100% attack rate and an incubation period not substantially longer than
feeding animals directly with scrapie brain homogenate. Furthermore, plants can
uptake prions from contaminated soil and transport them to different parts of
the plant tissue (stem and leaves). Similarly, prions bind tightly to a variety
of environmentally relevant surfaces, including stones, wood, metals, plastic,
glass, cement, etc. Prion contaminated surfaces efficiently transmit prion
disease when these materials were directly injected into the brain of animals
and strikingly when the contaminated surfaces were just placed in the animal
cage. These findings demonstrate that environmental materials can efficiently
bind infectious prions and act as carriers of infectivity, suggesting that they
may play an important role in the horizontal transmission of the disease.

Since its invention 13 years ago, PMCA has helped to answer fundamental
questions of prion propagation and has broad applications in research areas

Oral Transmissibility of Prion Disease Is Enhanced by Binding to Soil
Particles
Author Summary
Transmissible spongiform encephalopathies (TSEs) are a group of incurable
neurological diseases likely caused by a misfolded form of the prion protein.
TSEs include scrapie in sheep, bovine spongiform encephalopathy (‘‘mad cow’’
disease) in cattle, chronic wasting disease in deer and elk, and
Creutzfeldt-Jakob disease in humans. Scrapie and chronic wasting disease are
unique among TSEs because they can be transmitted between animals, and the
disease agents appear to persist in environments previously inhabited by
infected animals. Soil has been hypothesized to act as a reservoir of
infectivity and to bind the infectious agent. In the current study, we orally
dosed experimental animals with a common clay mineral, montmorillonite, or whole
soils laden with infectious prions, and compared the transmissibility to unbound
agent. We found that prions bound to montmorillonite and whole soils remained
orally infectious, and, in most cases, increased the oral transmission of
disease compared to the unbound agent. The results presented in this study
suggest that soil may contribute to environmental spread of TSEs by increasing
the transmissibility of small amounts of infectious agent in the
environment.

Objects in contact with classical scrapie sheep act as a reservoir for
scrapie transmission
The sources of dust borne prions are unknown but it seems reasonable to
assume that faecal, urine, skin, parturient material and saliva-derived prions
may contribute to this mobile environmental reservoir of infectivity. This work
highlights a possible transmission route for scrapie within the farm
environment, and this is likely to be paralleled in CWD which shows strong
similarities with scrapie in terms of prion dissemination and disease
transmission. The data indicate that the presence of scrapie prions in dust is
likely to make the control of these diseases a considerable challenge.

Fate of Prions in Soil: A Review
Christen B. Smith, Clarissa J. Booth, and Joel A. Pedersen*
Several reports have shown that prions can persist in soil for several
years. Significant interest remains in developing methods that could be applied
to degrade PrPTSE in naturally contaminated soils. Preliminary research suggests
that serine proteases and the microbial consortia in stimulated soils and
compost may partially degrade PrPTSE. Transition metal oxides in soil (viz.
manganese oxide) may also mediate prion inactivation. Overall, the effect of
prion attachment to soil particles on its persistence in the environment is not
well understood, and additional study is needed to determine its implications on
the environmental transmission of scrapie and CWD.
P.161: Prion soil binding may explain efficient horizontal CWD transmission
Conclusion. Silty clay loam exhibits highly efficient prion binding,
inferring a durable environmental reservoir, and an efficient mechanism for
indirect horizontal CWD transmission.
>>>Another alternative would be an absolute prohibition on the
movement of deer within the state for any purpose. While this alternative would
significantly reduce the potential spread of CWD, it would also have the
simultaneous effect of preventing landowners and land managers from implementing
popular management strategies involving the movement of deer, and would deprive
deer breeders of the ability to engage in the business of buying and selling
breeder deer. Therefore, this alternative was rejected because the department
determined that it placed an avoidable burden on the regulated
community.<<<

Classical scrapie is an environmentally transmissible prion disease of
sheep and goats. Prions can persist and remain potentially infectious in the
environment for many years and thus pose a risk of infecting animals after
re-stocking. In vitro studies using serial protein misfolding cyclic
amplification (sPMCA) have suggested that objects on a scrapie affected sheep
farm could contribute to disease transmission. This in vivo study aimed to
determine the role of field furniture (water troughs, feeding troughs, fencing,
and other objects that sheep may rub against) used by a scrapie-infected sheep
flock as a vector for disease transmission to scrapie-free lambs with the prion
protein genotype VRQ/VRQ, which is associated with high susceptibility to
classical scrapie. When the field furniture was placed in clean accommodation,
sheep became infected when exposed to either a water trough (four out of five)
or to objects used for rubbing (four out of seven). This field furniture had
been used by the scrapie-infected flock 8 weeks earlier and had previously been
shown to harbor scrapie prions by sPMCA. Sheep also became infected (20 out of
23) through exposure to contaminated field furniture placed within pasture not
used by scrapie-infected sheep for 40 months, even though swabs from this
furniture tested negative by PMCA. This infection rate decreased (1 out of 12)
on the same paddock after replacement with clean field furniture. Twelve grazing
sheep exposed to field furniture not in contact with scrapie-infected sheep for
18 months remained scrapie free. The findings of this study highlight the role
of field furniture used by scrapie-infected sheep to act as a reservoir for
disease re-introduction although infectivity declines considerably if the field
furniture has not been in contact with scrapie-infected sheep for several
months. PMCA may not be as sensitive as VRQ/VRQ sheep to test for environmental
contamination.

Discussion
Classical scrapie is an environmentally transmissible disease because it
has been reported in naïve, supposedly previously unexposed sheep placed in
pastures formerly occupied by scrapie-infected sheep (4, 19, 20). Although the
vector for disease transmission is not known, soil is likely to be an important
reservoir for prions (2) where – based on studies in rodents – prions can adhere
to minerals as a biologically active form (21) and remain infectious for more
than 2 years (22). Similarly, chronic wasting disease (CWD) has re-occurred in
mule deer housed in paddocks used by infected deer 2 years earlier, which was
assumed to be through foraging and soil consumption (23).
Our study suggested that the risk of acquiring scrapie infection was
greater through exposure to contaminated wooden, plastic, and metal surfaces via
water or food troughs, fencing, and hurdles than through grazing. Drinking from
a water trough used by the scrapie flock was sufficient to cause infection in
sheep in a clean building. Exposure to fences and other objects used for rubbing
also led to infection, which supported the hypothesis that skin may be a vector
for disease transmission (9). The risk of these objects to cause infection was
further demonstrated when 87% of 23 sheep presented with PrPSc in lymphoid
tissue after grazing on one of the paddocks, which contained metal hurdles, a
metal lamb creep and a water trough in contact with the scrapie flock up to 8
weeks earlier, whereas no infection had been demonstrated previously in sheep
grazing on this paddock, when equipped with new fencing and field furniture.
When the contaminated furniture and fencing were removed, the infection rate
dropped significantly to 8% of 12 sheep, with soil of the paddock as the most
likely source of infection caused by shedding of prions from the
scrapie-infected sheep in this paddock up to a week earlier.
This study also indicated that the level of contamination of field
furniture sufficient to cause infection was dependent on two factors: stage of
incubation period and time of last use by scrapie-infected sheep. Drinking from
a water trough that had been used by scrapie sheep in the predominantly
pre-clinical phase did not appear to cause infection, whereas infection was
shown in sheep drinking from the water trough used by scrapie sheep in the later
stage of the disease. It is possible that contamination occurred through
shedding of prions in saliva, which may have contaminated the surface of the
water trough and subsequently the water when it was refilled. Contamination
appeared to be sufficient to cause infection only if the trough was in contact
with sheep that included clinical cases. Indeed, there is an increased risk of
bodily fluid infectivity with disease progression in scrapie (24) and CWD (25)
based on PrPSc detection by sPMCA. Although ultraviolet light and heat under
natural conditions do not inactivate prions (26), furniture in contact with the
scrapie flock, which was assumed to be sufficiently contaminated to cause
infection, did not act as vector for disease if not used for 18 months, which
suggest that the weathering process alone was sufficient to inactivate prions.
PrPSc detection by sPMCA is increasingly used as a surrogate for
infectivity measurements by bioassay in sheep or mice. In this reported study,
however, the levels of PrPSc present in the environment were below the limit of
detection of the sPMCA method, yet were still sufficient to cause infection of
in-contact animals. In the present study, the outdoor objects were removed from
the infected flock 8 weeks prior to sampling and were positive by sPMCA at very
low levels (2 out of 37 reactions). As this sPMCA assay also yielded 2 positive
reactions out of 139 in samples from the scrapie-free farm, the sPMCA assay
could not detect PrPSc on any of the objects above the background of the assay.
False positive reactions with sPMCA at a low frequency associated with de novo
formation of infectious prions have been reported (27, 28). This is in contrast
to our previous study where we demonstrated that outdoor objects that had been
in contact with the scrapie-infected flock up to 20 days prior to sampling
harbored PrPSc that was detectable by sPMCA analysis [4 out of 15 reactions
(12)] and was significantly more positive by the assay compared to analogous
samples from the scrapie-free farm. This discrepancy could be due to the use of
a different sPMCA substrate between the studies that may alter the efficiency of
amplification of the environmental PrPSc. In addition, the present study had a
longer timeframe between the objects being in contact with the infected flock
and sampling, which may affect the levels of extractable PrPSc. Alternatively,
there may be potentially patchy contamination of this furniture with PrPSc,
which may have been missed by swabbing. The failure of sPMCA to detect
CWD-associated PrP in saliva from clinically affected deer despite confirmation
of infectivity in saliva-inoculated transgenic mice was associated with as yet
unidentified inhibitors in saliva (29), and it is possible that the sensitivity
of sPMCA is affected by other substances in the tested material. In addition,
sampling of amplifiable PrPSc and subsequent detection by sPMCA may be more
difficult from furniture exposed to weather, which is supported by the
observation that PrPSc was detected by sPMCA more frequently in indoor than
outdoor furniture (12). A recent experimental study has demonstrated that
repeated cycles of drying and wetting of prion-contaminated soil, equivalent to
what is expected under natural weathering conditions, could reduce PMCA
amplification efficiency and extend the incubation period in hamsters inoculated
with soil samples (30). This seems to apply also to this study even though the
reduction in infectivity was more dramatic in the sPMCA assays than in the sheep
model. Sheep were not kept until clinical end-point, which would have enabled us
to compare incubation periods, but the lack of infection in sheep exposed to
furniture that had not been in contact with scrapie sheep for a longer time
period supports the hypothesis that prion degradation and subsequent loss of
infectivity occurs even under natural conditions.
In conclusion, the results in the current study indicate that removal of
furniture that had been in contact with scrapie-infected animals should be
recommended, particularly since cleaning and decontamination may not effectively
remove scrapie infectivity (31), even though infectivity declines considerably
if the pasture and the field furniture have not been in contact with
scrapie-infected sheep for several months. As sPMCA failed to detect PrPSc in
furniture that was subjected to weathering, even though exposure led to
infection in sheep, this method may not always be reliable in predicting the
risk of scrapie infection through environmental contamination. These results
suggest that the VRQ/VRQ sheep model may be more sensitive than sPMCA for the
detection of environmentally associated scrapie, and suggest that extremely low
levels of scrapie contamination are able to cause infection in susceptible sheep
genotypes.

Circulation of prions within dust on a scrapie affected farm

Abstract
Prion diseases are fatal neurological disorders that affect humans and
animals. Scrapie of sheep/goats and Chronic Wasting Disease (CWD) of deer/elk
are contagious prion diseases where environmental reservoirs have a direct link
to the transmission of disease. Using protein misfolding cyclic amplification we
demonstrate that scrapie PrPSc can be detected within circulating dusts that are
present on a farm that is naturally contaminated with sheep scrapie. The
presence of infectious scrapie within airborne dusts may represent a possible
route of infection and illustrates the difficulties that may be associated with
the effective decontamination of such scrapie affected premises.

Discussion
We present biochemical data illustrating the airborne movement of scrapie
containing material within a contaminated farm environment. We were able to
detect scrapie PrPSc within extracts from dusts collected over a 70 day period,
in the absence of any sheep activity. We were also able to detect scrapie PrPSc
within dusts collected within pasture at 30 m but not at 60 m distance away from
the scrapie contaminated buildings, suggesting that the chance of contamination
of pasture by scrapie contaminated dusts decreases with distance from
contaminated farm buildings. PrPSc amplification by sPMCA has been shown to
correlate with infectivity and amplified products have been shown to be
infectious [14,15]. These experiments illustrate the potential for low dose
scrapie infectivity to be present within such samples. We estimate low ng levels
of scrapie positive brain equivalent were deposited per m2 over 70 days, in a
barn previously occupied by sheep affected with scrapie. This movement of dusts
and the accumulation of low levels of scrapie infectivity within this
environment may in part explain previous observations where despite stringent
pen decontamination regimens healthy lambs still became scrapie infected after
apparent exposure from their environment alone [16]. The presence of sPMCA
seeding activity and by inference, infectious prions within dusts, and their
potential for airborne dissemination is highly novel and may have implications
for the spread of scrapie within infected premises. The low level circulation
and accumulation of scrapie prion containing dust material within the farm
environment will likely impede the efficient decontamination of such scrapie
contaminated buildings unless all possible reservoirs of dust are removed.
Scrapie containing dusts could possibly infect animals during feeding and
drinking, and respiratory and conjunctival routes may also be involved. It has
been demonstrated that scrapie can be efficiently transmitted via the nasal
route in sheep [17], as is also the case for CWD in both murine models and in
white tailed deer [18-20].
The sources of dust borne prions are unknown but it seems reasonable to
assume that faecal, urine, skin, parturient material and saliva-derived prions
may contribute to this mobile environmental reservoir of infectivity. This work
highlights a possible transmission route for scrapie within the farm
environment, and this is likely to be paralleled in CWD which shows strong
similarities with scrapie in terms of prion dissemination and disease
transmission. The data indicate that the presence of scrapie prions in dust is
likely to make the control of these diseases a considerable challenge.
***Moreover, sporadic disease has never been observed in breeding colonies
or primate research laboratories, most notably among hundreds of animals over
several decades of study at the National Institutes of Health25, and in nearly
twenty older animals continuously housed in our own facility.***

In Confidence - Perceptions of unconventional slow virus diseases of
animals in the USA - APRIL-MAY 1989 - G A H Wells
3. Prof. A. Robertson gave a brief account of BSE. The US approach was to
accord it a very low profile indeed. Dr. A Thiermann showed the picture in the
''Independent'' with cattle being incinerated and thought this was a fanatical
incident to be avoided in the US at all costs. ...
”The occurrence of CWD must be viewed against the contest of the locations
in which it occurred. It was an incidental and unwelcome complication of the
respective wildlife research programmes. Despite it’s subsequent recognition as
a new disease of cervids, therefore justifying direct investigation, no specific
research funding was forthcoming. The USDA veiwed it as a wildlife problem and
consequently not their province!” ...page 26.
*** Spraker suggested an interesting explanation for the occurrence of CWD.
The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr.
Bob Davis. At or abut that time, allegedly, some scrapie work was conducted at
this site. When deer were introduced to the pens they occupied ground that had
previously been occupied by sheep.

Could the Scrapie experiments back around 1964 at Moore Air Force near
Mission, Texas, could this area have been ground zero for CWD TSE Prion (besides
the CWD cases that have waltzed across the Texas, New Mexico border near WSMR
Trans Pecos region since around 2001)?
Epidemiology of Scrapie in the United States 1977
snip...
Scrapie Field Trial Experiments Mission, Texas
A Scrapie Field Trial was developed at Mission, Texas, to provide
additional information for the eradication program on the epidemiology of
natural scrapie. The Mission Field Trial Station is located on 450 acres of
pastureland, part of the former Moore Air Force Base, near Mission, Texas. It
was designed to bring previously exposed, and later also unexposed, sheep or
goats to the Station and maintain and breed them under close observation for
extended periods to determine which animals would develop scrapie and define
more closely the natural spread and other epidemiological aspects of the
disease.
The 547 previously exposed sheep brought to the Mission Station beginning
in 1964 were of the Cheviot, Hampshire, Montadale, or Suffolk breeds. They were
purchased as field outbreaks occurred, and represented 21 bloodlines in which
scrapie had been diagnosed. Upon arrival at the Station, the sheep were
maintained on pasture, with supplemental feeding as necessary. The station was
divided into 2 areas: (1) a series of pastures and-pens occupied by male animals
only, and (2) a series of pastures and pens occupied by females and young
progeny of both sexes. ...

The most frightening thing I have read all day is the report of Gambetti's
finding of a new strain of sporadic cjd in young people.........Dear God, what
in the name of all that is holy is that!!! If the US has different strains of
scrapie.....why???? than the UK...then would the same mechanisms that make
different strains of scrapie here make different strains of BSE...if the
patterns are different in sheep and mice for scrapie.....could not the BSE be
different in the cattle, in the mink, in the humans.......I really think the
slides or tissues and everything from these young people with the new strain of
sporadic cjd should be put up to be analyzed by many, many experts in
cjd........bse.....scrapie Scrape the damn slide and put it into
mice.....wait.....chop up the mouse brain and and spinal cord........put into
some more mice.....dammit amplify the thing and start the damned
research.....This is NOT rocket science...we need to use what we know and get
off our butts and move....the whining about how long everything takes.....well
it takes a whole lot longer if you whine for a year and then start the
research!!! Not sure where I read this but it was a recent press release or
something like that: I thought I would fall out of my chair when I read about
how there was no worry about infectivity from a histopath slide or tissues
because they are preserved in formic acid, or formalin or formaldehyde.....for
God's sake........ Ask any pathologist in the UK what the brain tissues in the
formalin looks like after a year.......it is a big fat sponge...the agent
continues to eat the brain ......you can't make slides anymore because the agent
has never stopped........and the old slides that are stained with Hemolysin and
Eosin......they get holier and holier and degenerate and continue...what you
looked at 6 months ago is not there........Gambetti better be photographing
every damned thing he is looking at.....
Okay, you need to know. You don't need to pass it on as nothing will come
of it and there is not a damned thing anyone can do about it. Don't even hint at
it as it will be denied and laughed at.......... USDA is gonna do as little as
possible until there is actually a human case in the USA of the nvcjd........if
you want to move this thing along and shake the earth....then we gotta get the
victims families to make sure whoever is doing the autopsy is credible,
trustworthy, and a saint with the courage of Joan of Arc........I am not
kidding!!!! so, unless we get a human death from EXACTLY the same form with
EXACTLY the same histopath lesions as seen in the UK nvcjd........forget any
action........it is ALL gonna be sporadic!!!
And, if there is a case.......there is gonna be every effort to link it to
international travel, international food, etc. etc. etc. etc. etc. They will go
so far as to find out if a sex partner had ever traveled to the UK/europe, etc.
etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth.
They have all the cards, all the money, and are willing to threaten and carry
out those threats....and this may be their biggest downfall...
Thanks as always for your help.
(Recently had a very startling revelation from a rather senior person in
government here..........knocked me out of my chair........you must keep
pushing. If I was a power person....I would be demanding that there be a least a
million bovine tested as soon as possible and agressively seeking this disease.
The big players are coming out of the woodwork as there is money to be made!!!
In short: "FIRE AT WILL"!!! for the very dumb....who's "will"! "Will be the
burden to bare if there is any coverup!"
again it was said years ago and it should be taken seriously....BSE will
NEVER be found in the US! As for the BSE conference call...I think you did a
great service to freedom of information and making some people feign
integrity...I find it scary to see that most of the "experts" are employed by
the federal government or are supported on the "teat" of federal funds. A scary
picture! I hope there is a confidential panel organized by the new government to
really investigate this thing.
You need to watch your back........but keep picking at them.......like a
buzzard to the bone...you just may get to the truth!!! (You probably have more
support than you know. Too many people are afraid to show you or let anyone else
know. I have heard a few things myself... you ask the questions that everyone
else is too afraid to ask.)
