| muellerius capillaris (mueller, 1889) (nematoda: protostrongylidae): an unusual finding in rocky mountain bighorn sheep (ovis canadensis canadensis shaw) in south dakota. | lungs and fecal samples from nine hunter-killed rocky mountain bighorn sheep were examined for lungworms. all samples contained adults and/or larvae of muellerius capillaris (mueller, 1889). protostrongylus spp., the lungworms commonly reported from bighorn sheep, were not present in any samples. larvae of m. capillaris bear a spine on the dorsal side of the posterior end and are shorter than dorsal-spined larvae of other lungworms recorded from north american ungulates. larvae similar in shape ... | 1984 | 6530714 |
| toxoplasmic encephalitis in a free-ranging rocky mountain bighorn sheep from washington. | a 4-mo-old free-ranging rocky mountain bighorn sheep (ovis canadensis canadensis) from the hells canyon area (washington, usa) was diagnosed with encephalitis associated with toxoplasma gondii infection. the sheep had concurrent pneumonic pasteurellosis and resided in a geographic area with endemic pasteurella-associated pneumonia and mortality in bighorn sheep. the brain had multifocal necrotizing and nonsuppurative encephalitis with intralesional protozoa. the protozoa were identified as t. go ... | 2000 | 11085438 |
| characterization of pasteurella multocida associated with pneumonia in bighorn sheep. | pasteurella multocida is a highly diverse group of bacteria recognized as important pathogens. although p. multocida is not ordinarily associated with disease in rocky mountain bighorn sheep (ovis canadensis canadensis), numerous isolates were cultured in high numbers from free-ranging bighorn sheep in the hells canyon area of idaho, washington, and oregon (usa) during the winter of 1995-96. animals captured in hells canyon and held in captivity, and their offspring, also harbored p. multocida. ... | 2003 | 14567214 |
| sharing of pasteurella spp. between free-ranging bighorn sheep and feral goats. | pasteurella spp. were isolated from feral goats and free-ranging bighorn sheep (ovis canadensis canadensis) in the hells canyon national recreation area bordering idaho, oregon, and washington (usa). biovariant 1 pasteurella haemolytica organisms were isolated from one goat and one of two bighorn sheep found in close association. both isolates produced leukotoxin and had identical electrophoretic patterns of dna fragments following cutting with restriction endonuclease haeiii. similarly pasteure ... | 2003 | 14733287 |
