bluetongue in free-ranging pronghorn antelope (antilocapra americana) in wyoming: 1976 and least 3,200 pronghorn (antilocapra americana) died during a bluetongue (bt) epizootic in eastern wyoming during late september and early october 1976. in august and september 1984, another bt epizootic occurred in northeastern wyoming resulting in 300 known pronghorn deaths. in 17 pronghorn examined postmortem, hemorrhages and edema were the most common gross pathologic changes. microscopic changes included hemorrhage, edema, arterial fibrinoid necrosis, lymphoid depletion in splenic and lymp ...19882832621
experimentally induced bluetongue virus infection in white-tailed deer: coagulation, clinical pathologic, and gross pathologic changes.ten yearling white-tailed deer (odocoileus virginianus) were inoculated with bluetongue virus serotype 17. two yearling white-tailed deer were inoculated with sonicated heparinized noninfected blood and served as controls. clinical signs of bluetongue virus infection included increased rectal temperature, erythema, facial edema, coronitis, and stomatitis. by postinoculation day (pid) 8, excessive bleeding and hematoma formation at venipuncture sites, dehydration, and diarrhea developed. at necro ...19882854709
experimentally induced bluetongue virus infection in white-tailed deer: ultrastructural findings.white-tailed deer (odocoileus virginianus) were inoculated with bluetongue virus serotype 17 and sequentially euthanatized during infection. ultrastructural changes in the microvasculature of tongue, buccal mucosa, heart, and pulmonary artery, platelets, and bone marrow were evaluated. bluetongue virus was found in endothelial cells of the microvasculature by postinoculation day 4. viral replication was associated with the development of viral matrices, viral-associated macrotubules, and aggrega ...19882854710
antibody prevalence of eight ruminant infectious diseases in california mule and black-tailed deer (odocoileus hemionus).we tested 276 sera from 18 free-ranging black-tailed and mule deer (odocoileus hemionus) herds in california (usa) collected from 1987 to 1991 in five biogeographical habitat types, for antibodies against eight infectious disease agents. overall antibody prevalence was 56% for anaplasma marginale, 31% for borrelia burgdorferi, 16% for bluetongue virus serotype 17, 15% for epizootic hemorrhagic disease virus, 7% for coxiella burnetii and toxoplasma gondii, respectively, and 0% for bovine leukosis ...19948151824
