Greetings Ranchers.net et al @ Bull Session,
thought _some_ of you might or should be interested in this.
for any of you ranchers that may be concerned about cwd, scrapie and cwd, and commingling there from, risk factors and such, if there are any still out there, see ;

*** Assessing the susceptibility of transgenic mice over-expressing deer prion protein to bovine spongiform encephalopathy
The present study was designed to assess the susceptibility of the prototypic mouse line, Tg(CerPrP)1536+/- to bovine spongiform encephalopathy (BSE) prions, which have the ability to overcome species barriers. Tg(CerPrP)1536+/- mice challenged with red deer-adapted BSE resulted in a 90-100% attack rates, BSE from cattle failed to transmit, indicating agent adaptation in the deer.

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed deer
snip...
After a natural route of exposure, 100% of WTD were susceptible to scrapie. ...This work demonstrates that WTD are highly susceptible to sheep scrapie, but on first passage, scrapie in WTD is differentiable from CWD.

Research Project: Virus and Prion Research Unit 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.
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
snip...
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.
