association of moraxella ovis with keratoconjunctivitis in mule deer and moose in wyoming.six cases of infectious keratoconjunctivitis (ikc) in mule deer (odocoileus hemionus) and moose (alces alces) in wyoming (usa) were investigated during fall and winter of 1995 and 1996. excessive lacrimation, mucopurulent conjunctivitis, keratitis, and corneal opacity were observed in mule deer. moose had severe mucopurulent conjunctivitis, keratitis, and corneal ulceration. hemolytic, non-piliated moraxella ovis was isolated from two mule deer and two moose. we attempted to reproduce ikc in thr ...200010813605
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 ...200011085429
bacteria and nematodes in the conjunctiva of mule deer from wyoming and utah.swabs of conjunctiva were collected from 44 live and 226 hunter-harvested mule deer (odocoileus hemionus) from wyoming and utah (usa). we identified 29 gram negative and 22 gram positive bacterial taxonomic categories, but many isolates from hunter-harvested animals were environmental contaminants. staphylococcus spp. and micrococcus spp. were the most common gram positive bacteria isolated, and enterobacter spp., escherichia coli, and pseudomonas spp. were common gram negative bacteria isolated ...200011085445
isolation of bovine viral diarrhea virus from a free-ranging mule deer in wyoming.a noncytopathic type 1a bovine viral diarrhea virus (bvdv) was isolated from a free-ranging yearling female mule deer (odocoileus hemionus) from northwestern wyoming (usa). the mule deer was emaciated, weak, and salivating, and arcanobacterium pyogenes was cultured from lung abscesses. bovine viral diarrhea virus was isolated from lung, however, bvdv antigen was not detected by immunohistochemistry. the bvdv genotype was determined by reverse transcriptase polymerase chain reaction and the rna s ...200111310881
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 ...200415148993
low frequency of prp genotype 225sf among free-ranging mule deer (odocoileus hemionus) with chronic wasting disease.the prion protein (prp) gene was characterized in 1482 free-ranging mule deer (odocoileus hemionus) from wyoming and colorado. using dna sequences from 363 deer, dimorphisms at codons 20 (aspartate/glycine) and 225 [serine (s)/phenylalanine (f)] were found; silent changes occurred at codons 131 (tyrosine) and 247 (isoleucine). the remaining samples were surveyed for codon 225 genotype and all were characterized for chronic wasting disease (cwd) infection status. a total of 112 deer with the geno ...200516033959
ocular plague (yersinia pestis) in mule deer (odocoileus hemionus) from wyoming and oregon.although plague is relatively rare in wild ungulates, this report describes ocular lesions associated with yersinia pestis infection in three free-ranging mule deer (odocoileus hemionus) from wyoming and oregon, usa. all deer were observed antemortem and seemed to be blind. post-mortem examination revealed gross lesions of bilateral keratoconjunctivitis and/or panophthalmitis in the first two deer, but only partial retinal detachment in the third deer. microscopically, all deer had moderate-to-s ...200818957655
echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...200919901399
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 ...201724336966
