| observations on epizootiology and distribution of elaeophora schneideri in montana ruminants. | seventy-four moose, 111 elk, 20 mule deer, 8 white-tailed deer, 26 prong-horn antelope, 42 domestic sheep and 3 bighorn sheep from montana or northwestern wyoming were examined post-mortem for evidence of elaeophora schneideri infection in 1973-74. fifteen percent of the mule deer and four percent of the moose were positive for adult arterial worms. this constitutes the first report of e. schneideri in mule deer in montana. no gross signs of blindness or other neurologic disorder were evident in ... | 1975 | 127848 |
| further studies on trypanosomers in game animals in wyoming. | blood samples were collected from captive and free-ranging elk (cervus canadensis), mule deer (odocoileus hemionus), white-tailed deer, (odocoileus virginianus), black-tailed deer (odocoileus hemionus columbianus), pronghorn (antilocapra americana), moose (alces alces), and bighorn sheep (ovis canadensis) for cultural evidence of trypanosoma sp. infection. eleven of 188 (12%) hunter-killed elk, 22 of 37 (59%) free-ranging elk, and 79 of 119 (66%) captive elk were culture positive in 1973-74. par ... | 1976 | 933315 |
| epizootiology of chronic wasting disease in free-ranging cervids in colorado and wyoming. | surveillance and epidemic modeling were used to study chronic wasting disease (cwd), a transmissible spongiform encephalopathy that occurs naturally among sympatric, free-ranging deer (odocoileus spp.) and rocky mountain elk (cervus elaphus nelsoni) populations in contiguous portions of northeastern colorado and southeastern wyoming (usa). we used clinical case submissions to identify endemic areas, then used immunohistochemistry to detect cwd-infected individuals among 5,513 deer and elk sample ... | 2000 | 11085429 |
| prion gene sequence variation within diverse groups of u.s. sheep, beef cattle, and deer. | prions are proteins that play a central role in transmissible spongiform encephalopathies in a variety of mammals. among the most notable prion disorders in ungulates are scrapie in sheep, bovine spongiform encephalopathy in cattle, and chronic wasting disease in deer. single nucleotide polymorphisms in the sheep prion gene ( prnp) have been correlated with susceptibility to natural scrapie in some populations. similar correlations have not been reported in cattle or deer; however, characterizat ... | 2003 | 14722726 |
| chronic wasting disease of cervids. | chronic wasting disease (cwd) has recently emerged in north america as an important prion disease of captive and free-ranging cervids (species in the deer family). cwd is the only recognized transmissible spongiform encephalopathy (tse) affecting free-ranging species. three cervid species, mule deer (odocoileus hemionus), white-tailed deer (o. virginianus), and rocky mountain elk (cervus elaphus nelsoni), are the only known natural hosts of cwd. endemic cwd is well established in southern wyomin ... | 2004 | 15148993 |
| the population history of endogenous retroviruses in mule deer (odocoileus hemionus). | mobile elements are powerful agents of genomic evolution and can be exceptionally informative markers for investigating species and population-level evolutionary history. while several studies have utilized retrotransposon-based insertional polymorphisms to resolve phylogenies, few population studies exist outside of humans. endogenous retroviruses are ltr-retrotransposons derived from retroviruses that have become stably integrated in the host genome during past infections and transmitted verti ... | 2017 | 24336966 |
| endemic chronic wasting disease causes mule deer population decline in wyoming. | chronic wasting disease (cwd) is a fatal transmissible spongiform encephalopathy affecting white-tailed deer (odocoileus virginianus), mule deer (odocoileus hemionus), rocky mountain elk (cervus elaphus nelsoni), and moose (alces alces shirasi) in north america. in southeastern wyoming average annual cwd prevalence in mule deer exceeds 20% and appears to contribute to regional population declines. we determined the effect of cwd on mule deer demography using age-specific, female-only, cwd transi ... | 2017 | 29049389 |
