epizootiology of bluetongue: the situation in the united states of america.bluetongue was first reported in the united states in 1948 in sheep in texas. the virus has now been isolated from sheep in 19 states. when the disease first occurs in a flock, the morbidity may reach 50 to 75% and mortality 20 to 50%. in subsequent years, the morbidity may be only 1 to 2% with very few deaths. difference in breed susceptibility has not been observed. natural bluetongue infection has not been observed in angora or dairy goats. bluetongue virus was first isolated from cattle, in ...1975169793
serological evidence of california serogroup virus activity in oregon.we wished to demonstrate evidence of the presence of california serogroup viruses in oregon and to test for the presence of certain other arboviruses in large ungulates. blood samples from black-tailed deer (odocoileus hemionus columbianus), mule deer (o. hemionus hemionus), and roosevelt elk (cervus elaphus roosevelti) from nine counties in oregon were tested by serum-dilution plaque reduction neutralization for antibody to california serogroup viruses, including snowshoe hare, california encep ...19873586196

equine cutaneous non-neoplastic nodular and proliferative lesions in the pacific northwest.a retrospective study examined data on cutaneous nodular and proliferative lesions in horses, donkeys and mules submitted to the veterinary diagnostic laboratory at oregon state university in a 3.5-year period. one hundred and sixteen non-neoplastic nodular and proliferative lesions were identified, comprising 18% of all lesions studied and 6.4% of total equine pathology accessions. exuberant granulation tissue, eosinophilic granuloma, fungal granuloma, cysts and habronaemiasis were most common, ...200516359312
survey of equine cutaneous neoplasia in the pacific northwest.a retrospective study examined data regarding equine cutaneous and mucocutaneous neoplasms submitted to the veterinary diagnostic laboratory at oregon state university in a 3.5-year period. a total of 536 neoplasms were identified, accounting for 30% of the total equine pathology submissions. sarcoid, squamous cell carcinoma, melanocytic tumors, papillomas, and mast cell tumors were the most common neoplasms, constituting 87.5% of all cutaneous neoplasms. sarcoids represented 51.4% of all neopla ...200616566271
muscleworms, parelaphostrongylus andersoni (nematoda: protostrongylidae), discovered in columbia white-tailed deer from oregon and washington: implications for biogeography and host associations.parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (odocoileus virginianus). host and geographic distribution for this parasite, however, remain poorly defined in the region of western north america. fecal samples collected from columbia white-tailed deer (o. v. leucurus) in a restricted range endemic to oregon and washington, usa, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. multilocus dna sequence data ( ...200818263818
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
bovicola tibialis (phthiraptera:trichodectidae): occurrence of an exotic chewing louse on cervids in north america.through a recent (2003-2007) survey of ectoparasites on hoofed mammals in western north america, a literature review, and examination of archived museum specimens, we found that the exotic deer-chewing louse, bovicola tibialis (piaget), is a long-term, widespread resident in the region. the earliest known collection was from salt spring island, canada, in 1941. we found these lice on the typical host, that is, introduced european fallow deer (dama dama l.), and on asian chital (axis axis [erxleb ...201121337942
epizootiology of sarcocystis infections in mule deer fawns in oregon.from 1974 to 1977, 62 wild mule deer (odocoileus hemionus) fawns from steens mountain, ore were euthanatized in autumn (23 deer), winter (21 deer), and spring (18 deer). the number of sarcocysts of sarcocystis spp was counted in histologic sections of various muscular organs. sarcocysts were seen in the muscle specimens of 14 of the 23 deer euthanatized in autumn (september to november) and in specimens from all 39 deer euthanatized in winter (december and january) and spring (march and april). ...19853935614
hybrid swarm between divergent lineages of mule deer (odocoileus hemionus).studies of hybrid zones have revealed an array of evolutionary outcomes, yet the underlying structure is typically characterized as one of three types: a hybrid zone, a hybrid swarm or a hybrid taxon. our primary objective was to determine which of these three structures best characterizes a zone of hybridization between two divergent lineages of mule deer (odocoileus hemionus), mule deer and black-tailed deer. these lineages are morphologically, ecologically and genetically distinct, yet hybrid ...201122066874
serosurvey for antibody to deerpox virus in five cervid species in oregon, usa.five cervid species in oregon, usa were tested with a serum neutralization assay for antibody to deerpox virus (dpv). none of the 50 elk (cervus elaphus ssp. roosevelti and nelsonii) had detectable antibody. prevalence of antibody to dpv in the remaining species was: 52% (n=55) in black-tailed deer (odocoileus hemionus columbianus), 32% (n= 59) in mule deer (o. hemionus hemionus), and 36% (n=50) in columbian white-tailed deer (o. virginianus leucurus), with an overall antibody prevalence of 40.2 ...201323307387
anticipating forest and range land development in central oregon (usa) for landscape analysis, with an example application involving mule deer.forest policymakers, public lands managers, and scientists in the pacific northwest (usa) seek ways to evaluate the landscape-level effects of policies and management through the multidisciplinary development and application of spatially explicit methods and models. the interagency mapping and analysis project (imap) is an ongoing effort to generate landscape-wide vegetation data and models to evaluate the integrated effects of disturbances and management activities on natural resource condition ...201020300934
