disease pops up in Douglas County; 300 animals euthanized
The euthanizing of 300
sheep from a Roseburg ranch shows health officials are vigilant about stopping a
livestock disease from spreading, the Oregon state veterinarian said
Sheep growers, though,
say they received too little information about the state’s first case of scrapie
“There’s an awful lot of
rumors going around. It seems like it would be appropriate to get as much
information out about scrapie as possible, because it impacts the market for all
of us,” said Oregon Sheep Growers Association President John Fine, a Dixonville
State Veterinarian Brad
LeaMaster said Thursday the 300 sheep were from a ranch east of Roseburg, though
he declined to identify the rancher.
One animal tested
positive for scrapie, a fatal brain disease in sheep and goats comparable to mad
cow disease, and the sheep were euthanized as a precaution, LeaMaster
“It’s not an outbreak.
It’s one sheep,” he said. “It’s not a threat to public safety. It’s certainly
not a food safety issue.”
For the past 10 years in
Oregon, the state and the U.S. Department of Agriculture have worked together on
a scrapie eradication campaign, said Lyndsay Cole, spokeswoman for the USDA’s
Animal and Plant Health Inspection Service.
She said the affected
Douglas County sheep was identified through a routine sampling of animals at a
slaughter plant. Blood tests were taken on the rest of the flock, and the sheep
identified as genetically susceptible to scrapie were euthanized.
“None of the meat from
any of the animals that were depopulated will enter the food chain,” Cole
LeaMaster said the
positive test for scrapie came back in late August, but the federal shutdown in
October delayed informing the public.
Scrapie has never been
known to transfer to people, and it’s not highly contagious, according to a USDA
The disease is thought to
most commonly spread from ewe to offspring and to other lambs that come in
contact with the placenta.
Early signs of scrapie
include the diseased animal scratching or rubbing against objects, like a fence
The USDA began an
eradication campaign a decade ago, hoping to prevent the economic damage
suffered by the beef industry because of mad cow disease.
This summer’s case of
scrapie was Oregon’s third since 2005.
In the past year, the
USDA has recorded 18 sheep with scrapie in the U.S., including the one in
Douglas County. LeaMaster said testing a live sheep for the disease remains
With about 22,800 ewes
valued at roughly $2.6 million, Douglas County is Oregon’s second-largest
sheep-producing county. The local sheep population can more than double between
December and March, when lambs are born. The American Sheep Industry estimates
that every 1,000 head of sheep is responsible for 18 full- or part-time
Rancher Jamie Pynch, whose family keeps about 250 head of sheep, said he’s heard
talk of scrapie showing up.
“It kind of makes you
nervous,” he said. “It’s the kind of thing you don’t ever think is going to
happen to you.”

nothing surprises me anymore $$$
Hello Garrett and Mr. Ackerman et al,
I don’t expect any of this to get published, bbbut, you needed to know the
rest of this ongoing nightmare.
don’t believe everything the USDA INC tells you $$$
there is, there was, and there has been, evidence to support a risk factor
of scrapie transmission to humans. this evidence has been around for
but sadly, political science, especially with the TSE prion disease,
overrules sound science every day by the industries and legislators, thanks to
the USDA and the OIE et al. ...
NOW, let's look at the evidence brought forth for the potential for
transmission of scrapie to humans ;
why do we not want to do TSE transmission studies on chimpanzees $
5. A positive result from a chimpanzee challenged severly would likely
create alarm in some circles even if the result could not be interpreted for
man. I have a view that all these agents could be transmitted provided a large
enough dose by appropriate routes was given and the animals kept long enough.
Until the mechanisms of the species barrier are more clearly understood it might
be best to retain that hypothesis.

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to
Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.
Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of sheep
and goats were transmitted to squirrel monkeys (Saimiri sciureus) that were
exposed to the infectious agents only by their nonforced consumption of known
infectious tissues. The asymptomatic incubation period in the one monkey exposed
to the virus of kuru was 36 months; that in the two monkeys exposed to the virus
of Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and that in the
two monkeys exposed to the virus of scrapie was 25 and 32 months, respectively.
Careful physical examination of the buccal cavities of all of the monkeys failed
to reveal signs or oral lesions. One additional monkey similarly exposed to kuru
has remained asymptomatic during the 39 months that it has been under
The successful transmission of kuru, Creutzfeldt-Jakob disease, and scrapie
by natural feeding to squirrel monkeys that we have reported provides further
grounds for concern that scrapie-infected meat may occasionally give rise in
humans to Creutzfeldt-Jakob disease.
Recently the question has again been brought up as to whether scrapie is
transmissible to man. This has followed reports that the disease has been
transmitted to primates. One particularly lurid speculation (Gajdusek 1977)
conjectures that the agents of scrapie, kuru, Creutzfeldt-Jakob disease and
transmissible encephalopathy of mink are varieties of a single "virus". The U.S.
Department of Agriculture concluded that it could "no longer justify or permit
scrapie-blood line and scrapie-exposed sheep and goats to be processed for human
or animal food at slaughter or rendering plants" (ARC 84/77)" The problem is
emphasised by the finding that some strains of scrapie produce lesions identical
to the once which characterise the human dementias"
Whether true or not. the hypothesis that these agents might be
transmissible to man raises two considerations. First, the safety of laboratory
personnel requires prompt attention. Second, action such as the "scorched meat"
policy of USDA makes the solution of the acrapie problem urgent if the sheep
industry is not to suffer grievously.

What if you can catch old-fashioned CJD by eating meat from a sheep

28 Mar 01
Like lambs to the slaughter 31 March 2001 by Debora MacKenzie Magazine
issue 2284. Subscribe and get 4 free issues. FOUR years ago, Terry Singeltary
watched his mother die horribly from a degenerative brain disease. Doctors told
him it was Alzheimer's, but Singeltary was suspicious. The diagnosis didn't fit
her violent symptoms, and he demanded an autopsy. It showed she had died of
sporadic Creutzfeldt-Jakob disease.
Most doctors believe that sCJD is caused by a prion protein deforming by
chance into a killer. But Singeltary thinks otherwise. He is one of a number of
campaigners who say that some sCJD, like the variant CJD related to BSE, is
caused by eating meat from infected animals. Their suspicions have focused on
sheep carrying scrapie, a BSE-like disease that is widespread in flocks across
Europe and North America.
Now scientists in France have stumbled across new evidence that adds weight
to the campaigners' fears. To their complete surprise, the researchers found
that one strain of scrapie causes the same brain damage in mice as sCJD.
"This means we cannot rule out that at least some sCJD may be caused by
some strains of scrapie," says team member Jean-Philippe Deslys of the French
Atomic Energy Commission's medical research laboratory in Fontenay-aux-Roses,
south-west of Paris. Hans Kretschmar of the University of Göttingen, who
coordinates CJD surveillance in Germany, is so concerned by the findings that he
now wants to trawl back through past sCJD cases to see if any might have been
caused by eating infected mutton or lamb.
Scrapie has been around for centuries and until now there has been no
evidence that it poses a risk to human health. But if the French finding means
that scrapie can cause sCJD in people, countries around the world may have
overlooked a CJD crisis to rival that caused by BSE.
Deslys and colleagues were originally studying vCJD, not sCJD. They
injected the brains of macaque monkeys with brain from BSE cattle, and from
French and British vCJD patients. The brain damage and clinical symptoms in the
monkeys were the same for all three. Mice injected with the original sets of
brain tissue or with infected monkey brain also developed the same
As a control experiment, the team also injected mice with brain tissue from
people and animals with other prion diseases: a French case of sCJD; a French
patient who caught sCJD from human-derived growth hormone; sheep with a French
strain of scrapie; and mice carrying a prion derived from an American scrapie
strain. As expected, they all affected the brain in a different way from BSE and
vCJD. But while the American strain of scrapie caused different damage from
sCJD, the French strain produced exactly the same pathology.
"The main evidence that scrapie does not affect humans has been
epidemiology," says Moira Bruce of the neuropathogenesis unit of the Institute
for Animal Health in Edinburgh, who was a member of the same team as Deslys.
"You see about the same incidence of the disease everywhere, whether or not
there are many sheep, and in countries such as New Zealand with no scrapie." In
the only previous comparisons of sCJD and scrapie in mice, Bruce found they were
But there are more than 20 strains of scrapie, and six of sCJD. "You would
not necessarily see a relationship between the two with epidemiology if only
some strains affect only some people," says Deslys. Bruce is cautious about the
mouse results, but agrees they require further investigation. Other trials of
scrapie and sCJD in mice, she says, are in progress.
People can have three different genetic variations of the human prion
protein, and each type of protein can fold up two different ways. Kretschmar has
found that these six combinations correspond to six clinical types of sCJD: each
type of normal prion produces a particular pathology when it spontaneously
deforms to produce sCJD.
But if these proteins deform because of infection with a disease-causing
prion, the relationship between pathology and prion type should be different, as
it is in vCJD. "If we look at brain samples from sporadic CJD cases and find
some that do not fit the pattern," says Kretschmar, "that could mean they were
caused by infection."
There are 250 deaths per year from sCJD in the US, and a similar incidence
elsewhere. Singeltary and other US activists think that some of these people
died after eating contaminated meat or "nutritional" pills containing dried
animal brain. Governments will have a hard time facing activists like Singeltary
if it turns out that some sCJD isn't as spontaneous as doctors have
Deslys's work on macaques also provides further proof that the human
disease vCJD is caused by BSE. And the experiments showed that vCJD is much more
virulent to primates than BSE, even when injected into the bloodstream rather
than the brain. This, says Deslys, means that there is an even bigger risk than
we thought that vCJD can be passed from one patient to another through
contaminated blood transfusions and surgical instruments.

Abstract Scrapie in small ruminants belongs to transmissible spongiform
encephalopathies (TSEs), or prion diseases, a family of fatal neurodegenerative
disorders that affect humans and animals and can transmit within and between
species by ingestion or inoculation. Conversion of the host-encoded prion
protein (PrP), normal cellular PrP (PrPc), into a misfolded form, abnormal PrP
(PrPSc), plays a key role in TSE transmission and pathogenesis. The intensified
surveillance of scrapie in the European Union, together with the improvement of
PrPSc detection techniques, has led to the discovery of a growing number of
so-called atypical scrapie cases. These include clinical Nor98 cases first
identified in Norwegian sheep on the basis of unusual pathological and PrPSc
molecular features and "cases" that produced discordant responses in the rapid
tests currently applied to the large-scale random screening of slaughtered or
fallen animals. Worryingly, a substantial proportion of such cases involved
sheep with PrP genotypes known until now to confer natural resistance to
conventional scrapie. Here we report that both Nor98 and discordant cases,
including three sheep homozygous for the resistant PrPARR allele (A136R154R171),
efficiently transmitted the disease to transgenic mice expressing ovine PrP, and
that they shared unique biological and biochemical features upon propagation in

unrecognized until recently, infects sheep and goat flocks and may have
important implications in terms of scrapie control and public health.

Italy; 2Dipartimento di Scienze Neurologiche, Università di Bologna; Bologna,
Italy; 3Case Western Reserve University; Cleveland, OH USA
Background. Variably protease-sensitive prionopathy (VPSPr) is a recently
described “sporadic”neurodegenerative disease involving prion protein
aggregation, which has clinical similarities with non-Alzheimer dementias, such
as fronto-temporal dementia. Currently, 30 cases of VPSPr have been reported in
Europe and USA, of which 19 cases were homozygous for valine at codon 129 of the
prion protein (VV), 8 were MV and 3 were MM. A distinctive feature of VPSPr is
the electrophoretic pattern of PrPSc after digestion with proteinase K (PK).
After PK-treatment, PrP from VPSPr forms a ladder-like electrophoretic pattern
similar to that described in GSS cases. The clinical and pathological features
of VPSPr raised the question of the correct classification of VPSPr among prion
diseases or other forms of neurodegenerative disorders. Here we report
preliminary data on the transmissibility and pathological features of VPSPr
cases in bank voles.
Materials and Methods. Seven VPSPr cases were inoculated in two genetic
lines of bank voles, carrying either methionine or isoleucine at codon 109 of
the prion protein (named BvM109 and BvI109, respectively). Among the VPSPr cases
selected, 2 were VV at PrP codon 129, 3 were MV and 2 were MM. Clinical
diagnosis in voles was confirmed by brain pathological assessment and western
blot for PK-resistant PrPSc (PrPres) with mAbs SAF32, SAF84, 12B2 and 9A2.
Results. To date, 2 VPSPr cases (1 MV and 1 MM) gave positive transmission
in BvM109. Overall, 3 voles were positive with survival time between 290 and 588
d post inoculation (d.p.i.). All positive voles accumulated PrPres in the form
of the typical PrP27–30, which was indistinguishable to that previously observed
in BvM109 inoculated with sCJDMM1 cases.
In BvI109, 3 VPSPr cases (2 VV and 1 MM) showed positive transmission until
now. Overall, 5 voles were positive with survival time between 281 and 596
d.p.i.. In contrast to what observed in BvM109, all BvI109 showed a GSS-like
PrPSc electrophoretic pattern, characterized by low molecular weight PrPres.
These PrPres fragments were positive with mAb 9A2 and 12B2, while being negative
with SAF32 and SAF84, suggesting that they are cleaved at both the C-terminus
and the N-terminus. Second passages are in progress from these first successful
Conclusions. Preliminary results from transmission studies in bank voles
strongly support the notion that VPSPr is a transmissible prion disease.
Interestingly, VPSPr undergoes divergent evolution in the two genetic lines of
voles, with sCJD-like features in BvM109 and GSS-like properties in
The discovery of previously unrecognized prion diseases in both humans and
animals (i.e., Nor98 in small ruminants) demonstrates that the range of prion
diseases might be wider than expected and raises crucial questions about the
epidemiology and strain properties of these new forms. We are investigating this
latter issue by molecular and biological comparison of VPSPr, GSS and Nor98.

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
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.)
