MDC encourages Missourians to share opinions on protecting deer
|
MDC’s statewide proposed regulations include:
Banning the importation of live white-tailed deer, mule deer, and their
hybrids from other states;
YES !
Improving fencing requirements for new and expanding captive-cervid
facilities;
YES !
Requiring all deer six months or older that die in captive-cervid
facilities to be tested for Chronic Wasting Disease;
YES !
Establishing better record-keeping requirements for captive-cervid
operations; and YES !
Prohibiting any new captive-cervid facilities within 25 miles of where
Chronic Wasting Disease has been confirmed.
YES, but, I would prefer a moratorium, on any and all new captive-cervid
facilities, until a live test is available, and when that happens, all captive
cervid are to be tested once a year and every dead cervid must be tested (any
missing deer without records and trace forward, the captive facility should be
immediately shut down, until said records are found, if not found, like the
recent captive escapees from the cwd index herd in PA to LA and who knows where
else, the facility should be shut down permanently, and at the cost of the
captive farm, with heavy fines and penalties, and or when any cervid is sold,
and until the cwd program is made to be MANDATORY, instead of voluntary). I also
believe that it is the responsibility of all game farms, shooting pens, sperm
mills, antler mills, urine mills, velvet mills, to have insurance not just to
cover their loss, but to also cover the loss to the state, if CWD is documented
any said facilities. once cwd is established, that land is worthless for years,
if not decades to come, therefore will not be worth much, if you can use it at
all. ...

*** Wisconsin 16 age limit on testing dead deer Game Farm CWD Testing
Protocol Needs To Be Revised
Approximately 4,200 fawns, defined as deer under 1 year of age, were
sampled from the eradication zone over the last year. The majority of fawns
sampled were between the ages of 5 to 9 months, though some were as young as 1
month.
*** Two of the six fawns with CWD detected were 5 to 6 months old.
All six of the positive fawns were taken from the core area of the CWD
eradication zone where the highest numbers of positive deer have been
identified.

Between 1996 and 2002, chronic wasting disease was diagnosed in 39 herds of
farmed elk in Saskatchewan in a single epidemic. All of these herds were
depopulated as part of the Canadian Food Inspection Agency’s (CFIA) disease
eradication program. Animals, primarily over 12 mo of age, were tested for the
presence CWD prions following euthanasia. Twenty-one of the herds were linked
through movements of live animals with latent CWD from a single infected source
herd in Saskatchewan, 17 through movements of animals from 7 of the secondarily
infected herds.
***The source herd is believed to have become infected via importation of
animals from a game farm in South Dakota where CWD was subsequently diagnosed
(7,4). A wide range in herd prevalence of CWD at the time of herd depopulation
of these herds was observed. Within-herd transmission was observed on some
farms, while the disease remained confined to the introduced animals on other
farms.

Chronic Wasting Disease (CWD) outbreaks and surveillance program in the
Republic of Korea Chronic Wasting Disease (CWD) outbreaks and surveillance
program in the Republic of Korea

Division, National Veterinary Research and Quarantine Service, Republic of Korea
Chronic wasting disease (CWD) has been recognized as an important prion
disease in native North America deer and Rocky mountain elks. The disease is a
unique member of the transmissible spongiform encephalopathies (TSEs), which
naturally affects only a few species. CWD had been limited to USA and Canada
until 2000.
On 28 December 2000, information from the Canadian government showed that a
total of 95 elk had been exported from farms with CWD to Korea. These consisted
of 23 elk in 1994 originating from the so-called “source farm” in Canada, and 72
elk in 1997, which had been held in pre export quarantine at the “source
farm”.Based on export information of CWD suspected elk from Canada to Korea, CWD
surveillance program was initiated by the Ministry of Agriculture and Forestry
(MAF) in 2001.
All elks imported in 1997 were traced back, however elks imported in 1994
were impossible to identify. CWD control measures included stamping out of all
animals in the affected farm, and thorough cleaning and disinfection of the
premises. In addition, nationwide clinical surveillance of Korean native
cervids, and improved measures to ensure reporting of CWD suspect cases were
implemented.
Total of 9 elks were found to be affected. CWD was designated as a
notifiable disease under the Act for Prevention of Livestock Epidemics in 2002.
Additional CWD cases - 12 elks and 2 elks - were diagnosed in 2004 and
2005.
Since February of 2005, when slaughtered elks were found to be positive,
all slaughtered cervid for human consumption at abattoirs were designated as
target of the CWD surveillance program. Currently, CWD laboratory testing is
only conducted by National Reference Laboratory on CWD, which is the Foreign
Animal Disease Division (FADD) of National Veterinary Research and Quarantine
Service (NVRQS).
In July 2010, one out of 3 elks from Farm 1 which were slaughtered for the
human consumption was confirmed as positive. Consequently, all cervid – 54 elks,
41 Sika deer and 5 Albino deer – were culled and one elk was found to be
positive. Epidemiological investigations were conducted by Veterinary
Epidemiology Division (VED) of NVRQS in collaboration with provincial veterinary
services.
Epidemiologically related farms were found as 3 farms and all cervid at
these farms were culled and subjected to CWD diagnosis. Three elks and 5
crossbreeds (Red deer and Sika deer) were confirmed as positive at farm 2.
All cervids at Farm 3 and Farm 4 – 15 elks and 47 elks – were culled and
confirmed as negative.
Further epidemiological investigations showed that these CWD outbreaks were
linked to the importation of elks from Canada in 1994 based on circumstantial
evidences.
In December 2010, one elk was confirmed as positive at Farm 5.
Consequently, all cervid – 3 elks, 11 Manchurian Sika deer and 20 Sika deer –
were culled and one Manchurian Sika deer and seven Sika deer were found to be
positive. This is the first report of CWD in these sub-species of deer.
Epidemiological investigations found that the owner of the Farm 2 in CWD
outbreaks in July 2010 had co-owned the Farm 5.
In addition, it was newly revealed that one positive elk was introduced
from Farm 6 of Jinju-si Gyeongsang Namdo. All cervid – 19 elks, 15 crossbreed
(species unknown) and 64 Sika deer – of Farm 6 were culled, but all confirmed as
negative.

PRION 2014 CONFERENCE
CHRONIC WASTING DISEASE CWD
A FEW FINDINGS ;
Conclusions. To our knowledge, this is the first established experimental
model of CWD in TgSB3985. We found evidence for co-existence or divergence of
two CWD strains adapted to Tga20 mice and their replication in TgSB3985 mice.
Finally, we observed phenotypic differences between cervid-derived CWD and
CWD/Tg20 strains upon propagation in TgSB3985 mice. Further studies are underway
to characterize these strains.
We conclude that TSE infectivity is likely to survive burial for long time
periods with minimal loss of infectivity and limited movement from the original
burial site. However PMCA results have shown that there is the potential for
rainwater to elute TSE related material from soil which could lead to the
contamination of a wider area. These experiments reinforce the importance of
risk assessment when disposing of TSE risk materials.
The results show that even highly diluted PrPSc can bind efficiently to
polypropylene, stainless steel, glass, wood and stone and propagate the
conversion of normal prion protein. For in vivo experiments, hamsters were ic
injected with implants incubated in 1% 263K-infected brain homogenate. Hamsters,
inoculated with 263K-contaminated implants of all groups, developed typical
signs of prion disease, whereas control animals inoculated with non-contaminated
materials did not.
Our data establish that meadow voles are permissive to CWD via peripheral
exposure route, suggesting they could serve as an environmental reservoir for
CWD. Additionally, our data are consistent with the hypothesis that at least two
strains of CWD circulate in naturally-infected cervid populations and provide
evidence that meadow voles are a useful tool for CWD strain typing.
Conclusion. CWD prions are shed in saliva and urine of infected deer as
early as 3 months post infection and throughout the subsequent >1.5 year
course of infection. In current work we are examining the relationship of
prionemia to excretion and the impact of excreted prion binding to surfaces and
particulates in the environment.
Conclusion. CWD prions (as inferred by prion seeding activity by RT-QuIC)
are shed in urine of infected deer as early as 6 months post inoculation and
throughout the subsequent disease course. Further studies are in progress
refining the real-time urinary prion assay sensitivity and we are examining more
closely the excretion time frame, magnitude, and sample variables in
relationship to inoculation route and prionemia in naturally and experimentally
CWD-infected cervids.
Conclusions. Our results suggested that the odds of infection for CWD is
likely controlled by areas that congregate deer thus increasing direct
transmission (deer-to-deer interactions) or indirect transmission
(deer-to-environment) by sharing or depositing infectious prion proteins in
these preferred habitats. Epidemiology of CWD in the eastern U.S. is likely
controlled by separate factors than found in the Midwestern and endemic areas
for CWD and can assist in performing more efficient surveillance efforts for the
region.
Conclusions. During the pre-symptomatic stage of CWD infection and
throughout the course of disease deer may be shedding multiple LD50 doses per
day in their saliva. CWD prion shedding through saliva and excreta may account
for the unprecedented spread of this prion disease in nature.
P.28: Modeling prion species barriers and the new host effect using RT-QuIC
Kristen A Davenport, Davin M Henderson, Candace K Mathiason, and Edward A
Hoover Prion Research Center; Colorado State University; Fort Collins, CO USA
The propensity for trans-species prion transmission is related to the
structural characteristics of the enciphering and heterologous PrP, but the
exact mechanism remains mostly mysterious.
Studies of the effects of primary or tertiary prion protein
www.landesbioscience.com Prion 37 structures on trans-species prion transmission
have relied upon animal bioassays, making the influence of prion protein
structure vs. host co-factors (e.g. cellular constituents, trafficking, and
innate immune interactions) difficult to dissect.
As an alternative strategy, we are using real-time quaking-induced
conversion (RT-QuIC) to investigate the propensity for and the kinetics of
trans-species prion conversion. RT-QuIC has the advantage of providing more
defined conditions of seeded conversion to study the specific role of native
PrP:PrPRES interactions as a component of the species barrier.
We are comparing chronic wasting disease (CWD) and bovine spongiform
encephalopathy (BSE) prions by seeding each prion into its native host recPrP
(full-length bovine recPrP, or white tail deer recPrP) vs. into the heterologous
species.
Upon establishing the characteristics of intra-species and inter-species
prion seeding for CWD and BSE prions, we will evaluate the seeding kinetics and
cross-species seeding efficiencies of BSE and CWD passaged into a common new
host—feline—shown to be a permissive host for both CWD and BSE.
*** We hypothesize that both BSE prions and CWD prions passaged through
felines will seed human recPrP more efficiently than BSE or CWD from the
original hosts, evidence that the new host will dampen the species barrier
between humans and BSE or CWD. The new host effect is particularly relevant as
we investigate potential means of trans-species transmission of prion disease.
