| the role of deer as a possible reservoir host of potosi virus, a newly recognized arbovirus in the united states. | potosi (pot) virus (bunyaviridae) was isolated from aedes albopictus, an introduced asian mosquito species, collected at a used tire yard in potosi, missouri (usa), in august and september, 1989. in september, 1990, small animals were trapped at the tire yard and six cattle were sampled at an adjacent farm; in november 1990 and 1991, blood samples were collected with filter paper strips from 364 hunter-killed, white-tailed deer (odocoileus virginianus) in the region to determine the possible res ... | 1996 | 8827670 |
| spongiform encephalopathy in free-ranging mule deer (odocoileus hemionus), white-tailed deer (odocoileus virginianus) and rocky mountain elk (cervus elaphus nelsoni) in northcentral colorado. | between march 1981 and june 1995, a neurological disease characterized histologically by spongiform encephalopathy was diagnosed in 49 free-ranging cervids from northcentral colorado (usa). mule deer (odocoileus hemionus) were the primary species affected and accounted for 41 (84%) of the 49 cases, but six rocky mountain elk (cervus elaphus nelsoni) and two white-tailed deer (odocoileus virginianus) were also affected. clinical signs included emaciation, excessive salivation, behavioral changes, ... | 1997 | 9027685 |
| 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 |
| 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 |
| persistent bovine viral diarrhea virus infection in wild cervids of colorado. | bovine viral diarrhea virus (bvdv) is a significant viral pathogen of domestic cattle. worldwide, there is evidence of bvdv exposure and infection in wild ungulates; however, the frequency and significance of such events are unknown. to determine the prevalence and distribution of colorado deer, elk, and moose persistently infected (pi) with bvdv, a cross-sectional study was conducted using full-thickness ear tissue samples collected from animals presented to the colorado division of wildlife fo ... | 2008 | 18776103 |
| prion sequence polymorphisms and chronic wasting disease resistance in illinois white-tailed deer (odocoileus virginianus). | nucleic acid sequences of the prion gene (prnp) were examined and genotypes compiled for 76 white-tailed deer from northern illinois, which previously tested positive for chronic wasting disease (cwd), and 120 negative animals selected to control for geographic location and age. nine nucleotide polymorphisms, seven silent and two coding, were found in the sampled population. all observed polymorphisms except two of very low frequency were observed in both negative and positive animals, although ... | 2008 | 19164895 |
| new records of hair follicle mites (demodecidae) from north american cervidae. | individuals of three species of cervids, with varying degrees of alopecia, were examined for ectoparasites: rocky mountain elk (cervus elaphus nelsoni) and mule deer (odocoileus hemionus hemionus) in colorado and white-tailed deer (odocoileus virginianus) in south dakota. hair follicle mites were recovered and identified as demodex kutzeri, a species originally described from the european red deer (cervus elaphus, from austria) and the sika deer (cervus nippon pseudaxis, captive in germany). the ... | 2010 | 20688655 |
| epizootic hemorrhagic disease outbreak in a captive facility housing white-tailed deer (odocoileus virginianus), bison (bison bison), elk (cervus elaphus), cattle (bos taurus), and goats (capra hircus) in colorado, u.s.a. | an ungulate research facility in fort collins, colorado, u.s.a., experienced mortality in white-tailed deer (odocoileus virginianus) because of epizootic hemorrhagic disease virus (ehdv) infection from 20 august 2007 through 26 september 2007. epizootic hemorrhagic disease virus (ehdv) was detected by reverse transcriptase polymerase chain reaction and virus isolation from the spleen and lung tissues of two white-tailed deer. virus neutralization tests were performed on pre- and postoutbreak ser ... | 2010 | 20945651 |
