Antibody responses were examined among 998 bighorn sheep (Ovis canadensis) in California (USA) to determine spatial patterns of pathogen exposure. Using a shifting frame analysis, a specific geographic region was delineated that contained bighorn she

In 1989, herpesviruses were isolated from nasal swabs taken from two peninsular bighorn sheep (Ovis canadensis cremnobates) in the Anza-Borrego Desert State Park, San Diego County, California (USA). Using restriction endonuclease analysis (REA) with

Sera (n = 806) from 50 populations of bighorn sheep (Ovis canadensis) in California (USA) were evaluated for antibodies to Psoroptes sp. mites using a kinetic enzyme-linked immunosorbent assay (ELISA). Test values for each sample were determined to b

Six hundred thirty-four bighorn sheep (Ovis canadensis) were captured in the western United States between 1980 and 1986, using four different methods: drop-net (n = 158), drive-net (n = 249), chemical immobilization (n = 90) and net-gun (n = 137). T
