Dr. James C. Kroll Texas deer czar final report on Wisconsin
Friday, June 01, 2012
*** TEXAS DEER CZAR TO WISCONSIN ASK TO EXPLAIN COMMENTS
snip...
yep, while the Texas deer czar dr. dough was off to Wisconsin pushing the
privately owned shooting pen industry (livestock cervids industry), Texas fell
to CWD, and Texas just reported 4 more CWD postives. ...
for your information...
According to Wisconsin’s White-Tailed Deer Trustee Dr. James Kroll, people
who call for more public hunting opportunities are “pining for socialism.” He
further states, “(Public) Game management is the last bastion of communism.”
“Game Management,” says James Kroll, driving to his high-fenced,
two-hundred-acre spread near Nacogdoches, “is the last bastion of communism.”
Kroll, also known as Dr. Deer, is the director of the Forestry Resources
Institute of Texas at Stephen F. Austin State University, and the “management”
he is referring to is the sort practiced by the State of Texas. The 55-year-old
Kroll is the leading light in the field of private deer management as a means to
add value to the land. His belief is so absolute that some detractors refer to
him as Dr. Dough, implying that his eye is on the bottom line more than on the
natural world.
Kroll, who has been the foremost proponent of deer ranching in Texas for
more than thirty years, doesn’t mind the controversy and certainly doesn’t fade
in the heat. People who call for more public lands are “cocktail
conservationists,” he says, who are really pining for socialism. He calls
national parks “wildlife ghettos” and flatly accuses the government of gross
mismanagement. He argues that his relatively tiny acreage, marked by eight-foot
fences and posted signs warning off would-be poachers, is a better model for
keeping what’s natural natural while making money off the land.

In the USA, under the Food and Drug Administration’s BSE Feed Regulation
(21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin)
from deer and elk is prohibited for use in feed for ruminant animals. With
regards to feed for non-ruminant animals, under FDA law, CWD positive deer may
not be used for any animal feed or feed ingredients. For elk and deer considered
at high risk for CWD, the FDA recommends that these animals do not enter the
animal feed system. However, this recommendation is guidance and not a
requirement by law.
Animals considered at high risk for CWD include:
1) animals from areas declared to be endemic for CWD and/or to be CWD
eradication zones and
2) deer and elk that at some time during the 60-month period prior to
slaughter were in a captive herd that contained a CWD-positive animal.
Therefore, in the USA, materials from cervids other than CWD positive
animals may be used in animal feed and feed ingredients for non-ruminants.
The amount of animal PAP that is of deer and/or elk origin imported from
the USA to GB can not be determined, however, as it is not specified in TRACES.
It may constitute a small percentage of the 8412 kilos of non-fish origin
processed animal proteins that were imported from US into GB in 2011.
Overall, therefore, it is considered there is a __greater than negligible
risk___ that (nonruminant) animal feed and pet food containing deer and/or elk
protein is imported into GB.
There is uncertainty associated with this estimate given the lack of data
on the amount of deer and/or elk protein possibly being imported in these
products.
snip...
36% in 2007 (Almberg et al., 2011). In such areas, population declines of
deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of
Colorado, the prevalence can be as high as 30% (EFSA, 2011).
The clinical signs of CWD in affected adults are weight loss and
behavioural changes that can span weeks or months (Williams, 2005). In addition,
signs might include excessive salivation, behavioural alterations including a
fixed stare and changes in interaction with other animals in the herd, and an
altered stance (Williams, 2005). These signs are indistinguishable from cervids
experimentally infected with bovine spongiform encephalopathy (BSE).
Given this, if CWD was to be introduced into countries with BSE such as GB,
for example, infected deer populations would need to be tested to differentiate
if they were infected with CWD or BSE to minimise the risk of BSE entering the
human food-chain via affected venison.
snip...
The rate of transmission of CWD has been reported to be as high as 30% and
can approach 100% among captive animals in endemic areas (Safar et al., 2008).
snip...
In summary, in endemic areas, there is a medium probability that the soil
and surrounding environment is contaminated with CWD prions and in a
bioavailable form. In rural areas where CWD has not been reported and deer are
present, there is a greater than negligible risk the soil is contaminated with
CWD prion.
snip...
In summary, given the volume of tourists, hunters and servicemen moving
between GB and North America, the probability of at least one person travelling
to/from a CWD affected area and, in doing so, contaminating their clothing,
footwear and/or equipment prior to arriving in GB is greater than negligible.
For deer hunters, specifically, the risk is likely to be greater given the
increased contact with deer and their environment. However, there is significant
uncertainty associated with these estimates.
snip...
Therefore, it is considered that farmed and park deer may have a higher
probability of exposure to CWD transferred to the environment than wild deer
given the restricted habitat range and higher frequency of contact with tourists
and returning GB residents.

*** 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.

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed
deer
Justin Greenlee, Jodi Smith, Eric Nicholson US Dept. Agriculture;
Agricultural Research Service, National Animal Disease Center; Ames, IA USA
Interspecies transmission studies afford the opportunity to better
understand the potential host range and origins of prion diseases. The purpose
of these experiments was to determine susceptibility of white-tailed deer (WTD)
to scrapie and to compare the resultant clinical signs, lesions, and molecular
profiles of PrPSc to those of chronic wasting disease (CWD). We inoculated WTD
intracranially (IC; n = 5) and by a natural route of exposure (concurrent oral
and intranasal (IN); n = 5) with a US scrapie isolate. All deer were inoculated
with a 10% (wt/vol) brain homogenate from sheep with scrapie (1ml IC, 1 ml IN,
30 ml oral). All deer inoculated by the intracranial route had evidence of PrPSc
accumulation. PrPSc was detected in lymphoid tissues as early as 7
months-post-inoculation (PI) and a single deer that was necropsied at 15.6
months had widespread distribution of PrPSc highlighting that PrPSc is widely
distributed in the CNS and lymphoid tissues prior to the onset of clinical
signs. IC inoculated deer necropsied after 20 months PI (3/5) had clinical
signs, spongiform encephalopathy, and widespread distribution of PrPSc in neural
and lymphoid tissues. The results of this study suggest that there are many
similarities in the manifestation of CWD and scrapie in WTD after IC inoculation
including early and widespread presence of PrPSc in lymphoid tissues, clinical
signs of depression and weight loss progressing to wasting, and an incubation
time of 21-23 months. Moreover, western blots (WB) done on brain material from
the obex region have a molecular profile similar to CWD and distinct from
tissues of the cerebrum or the scrapie inoculum. However, results of microscopic
and IHC examination indicate that there are differences between the lesions
expected in CWD and those that occur in deer with scrapie: amyloid plaques were
not noted in any sections of brain examined from these deer and the pattern of
immunoreactivity by IHC was diffuse rather than plaque-like. After a natural
route of exposure, 100% of WTD were susceptible to scrapie. Deer developed
clinical signs of wasting and mental depression and were necropsied from 28 to
33 months PI. Tissues from these deer were positive for PrPSc by IHC and WB.
Similar to IC inoculated deer, samples from these deer exhibited two different
molecular profiles: samples from obex resembled CWD whereas those from cerebrum
were similar to the original scrapie inoculum. On further examination by WB
using a panel of antibodies, the tissues from deer with scrapie exhibit
properties differing from tissues either from sheep with scrapie or WTD with
CWD. Samples from WTD with CWD or sheep with scrapie are strongly immunoreactive
when probed with mAb P4, however, samples from WTD with scrapie are only weakly
immunoreactive. In contrast, when probed with mAb’s 6H4 or SAF 84, samples from
sheep with scrapie and WTD with CWD are weakly immunoreactive and samples from
WTD with scrapie are strongly positive. This work demonstrates that WTD are
highly susceptible to sheep scrapie, but on first passage, scrapie in WTD is
differentiable from CWD.

Scrapie in Deer: Comparisons and Contrasts to Chronic Wasting Disease (CWD)
Justin J. Greenlee of the Virus and Prion Diseases Research Unit, National
Animal Disease Center, ARS, USDA, Ames, IA provided a presentation on scrapie
and CWD in inoculated deer. Interspecies transmission studies afford the
opportunity to better understand the potential host range and origins of prion
diseases. We inoculated white-tailed deer intracranially (IC) and by a natural
route of exposure (concurrent oral and intranasal inoculation) with a US scrapie
isolate. All deer inoculated by the intracranial route had evidence of PrPSc
accumulation and those necropsied after 20 months post-inoculation (PI) (3/5)
had clinical signs, spongiform encephalopathy, and widespread distribution of
PrPSc in neural and lymphoid tissues. A single deer that was necropsied at 15.6
months PI did not have clinical signs, but had widespread distribution of PrPSc.
This highlights the facts that 1) prior to the onset of clinical signs PrPSc is
widely distributed in the CNS and lymphoid tissues and 2) currently used
diagnostic methods are sufficient to detect PrPSc prior to the onset of clinical
signs. The results of this study suggest that there are many similarities in the
manifestation of CWD and scrapie in white-tailed deer after IC inoculation
including early and widespread presence of PrPSc in lymphoid tissues, clinical
signs of depression and weight loss progressing to wasting, and an incubation
time of 21-23 months. Moreover, western blots (WB) done on brain material from
the obex region have a molecular profile consistent with CWD and distinct from
tissues of the cerebrum or the scrapie inoculum. However, results of microscopic
and IHC examination indicate that there are differences between the lesions
expected in CWD and those that occur in deer with scrapie: amyloid plaques were
not noted in any sections of brain examined from these deer and the pattern of
immunoreactivity by IHC was diffuse rather than plaque-like. After a natural
route of exposure, 100% of white-tailed deer were susceptible to scrapie. Deer
developed clinical signs of wasting and mental depression and were necropsied
from 28 to 33 months PI. Tissues from these deer were positive for scrapie by
IHC and WB. Tissues with PrPSc immunoreactivity included brain, tonsil,
retropharyngeal and mesenteric lymph nodes, hemal node, Peyer’s patches, and
spleen. While two WB patterns have been detected in brain regions of deer
inoculated by the natural route, unlike the IC inoculated deer, the pattern
similar to the scrapie inoculum predominates.
Committee Business:
The Committee discussed and approved three resolutions regarding CWD. They
can be found in the report of the Reswolutions Committee. Essentially the
resolutions urged USDA-APHIS-VS to:
Continue to provide funding for CWD testing of captive cervids
Finalize and publish the national CWD rule for Herd Certification and
Interstate Movement
Evaluate live animal test, including rectal mucosal biopsy, for CWD in
cervids

2011 Annual Report
In Objective 1, Assess cross-species transmissibility of transmissible
spongiform encephalopathies (TSEs) in livestock and wildlife, numerous
experiments assessing the susceptibility of various TSEs in different host
species were conducted. Most notable is deer inoculated with scrapie, which
exhibits similarities to chronic wasting disease (CWD) in deer suggestive of
sheep scrapie as an origin of CWD.
snip...
4.Accomplishments 1. Deer inoculated with domestic isolates of sheep
scrapie. Scrapie-affected deer exhibit 2 different patterns of disease
associated prion protein. In some regions of the brain the pattern is much like
that observed for scrapie, while in others it is more like chronic wasting
disease (CWD), the transmissible spongiform encephalopathy typically associated
with deer. This work conducted by ARS scientists at the National Animal Disease
Center, Ames, IA suggests that an interspecies transmission of sheep scrapie to
deer may have been the origin of CWD. This is important for husbandry practices
with both captive deer, elk and sheep for farmers and ranchers attempting to
keep their herds and flocks free of CWD and scrapie.
White-tailed Deer are Susceptible to Scrapie by Natural Route of Infection
Jodi D. Smith, Justin J. Greenlee, and Robert A. Kunkle; Virus and Prion
Research Unit, National Animal Disease Center, USDA-ARS
Interspecies transmission studies afford the opportunity to better
understand the potential host range and origins of prion diseases. Previous
experiments demonstrated that white-tailed deer are susceptible to sheep-derived
scrapie by intracranial inoculation. The purpose of this study was to determine
susceptibility of white-tailed deer to scrapie after a natural route of
exposure. Deer (n=5) were inoculated by concurrent oral (30 ml) and intranasal
(1 ml) instillation of a 10% (wt/vol) brain homogenate derived from a sheep
clinically affected with scrapie. Non-inoculated deer were maintained as
negative controls. All deer were observed daily for clinical signs. Deer were
euthanized and necropsied when neurologic disease was evident, and tissues were
examined for abnormal prion protein (PrPSc) by immunohistochemistry (IHC) and
western blot (WB). One animal was euthanized 15 months post-inoculation (MPI)
due to an injury. At that time, examination of obex and lymphoid tissues by IHC
was positive, but WB of obex and colliculus were negative. Remaining deer
developed clinical signs of wasting and mental depression and were necropsied
from 28 to 33 MPI. Tissues from these deer were positive for scrapie by IHC and
WB. Tissues with PrPSc immunoreactivity included brain, tonsil, retropharyngeal
and mesenteric lymph nodes, hemal node, Peyer’s patches, and spleen. This work
demonstrates for the first time that white-tailed deer are susceptible to sheep
scrapie by potential natural routes of inoculation. In-depth analysis of tissues
will be done to determine similarities between scrapie in deer after
intracranial and oral/intranasal inoculation and chronic wasting disease
resulting from similar routes of inoculation.

ANIMAL HEALTH ASSOCIATION September 29 – October 5, 2011
see updated 2012 RESOLUTIONS
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.
