Locoweed (Oxytropis sericea)—induced Lesions in Mule Deer (Odocoileius hemionus)

Locoweed (Oxytropis sericea)-induced lesions in mule deer (Odocoileius hemionus).

Locoweed poisoning has been reported in wildlife, but it is unknown whether mule deer (Odocoileius hemionus) are susceptible. In areas that are heavily infested with locoweed, deer and elk (Cervus elaphus nelsoni) have developed a spongiform encephalopathy, chronic wasting disease (CWD). Although these are distinct diseases, no good comparisons are available. The purpose of this study was to in...

Seroprevalence of Neospora caninum and Toxoplasma gondii in black-tailed deer (Odocoileus hemionus columbianus) and mule deer (Odocoileus hemionus hemionus).

Deer are considered important intermediate hosts for the coccidian parasites, Toxoplasma gondii and Neospora caninum. Antibodies to N. caninum and T. gondii were determined in sera of 42 mule deer (Odocoileus hemionus hemionus) and 43 black-tailed deer (Odocoileus hemionus columbianus) from Washington state, USA, using direct agglutination test with specific antigens. A titer of 1:25 was consid...

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 b...

Bovine tuberculosis in a free-ranging mule deer (Odocoileus hemionus) from Montana.

A survey of 41 mule deer (Odocoileus hemionus) and three white-tailed deer (O. virginianus) for bovine tuberculosis was conducted on a Montana (USA) cattle ranch from 2 November 1993 through January 1994. Gross and microscopic lesions typical of tuberculosis were present in tonsil and lymph nodes of the head, thorax, and abdomen of one adult female mule deer. Additionally, a single microgranulo...
