identification of ovine adenovirus types five and six in an epizootic of respiratory tract disease in recently weaned lambs.eight hundred fourteen polypay-cross lambs, 32 to 35 days old, were housed in an isolation barn under semiconfinement conditions. the lambs were observed twice daily for clinical signs of respiratory tract disease. during the 8-week observation period, an epizootic of respiratory tract disease developed, in which the combined morbidity and mortality was approximately 13%. the overall mortality was 4.1%, of which 57.6% was attributable to pneumonia. pasteurella haemolytica was isolated from 11 (5 ...19873038805
bacteria isolated from nasal and tonsillar samples of clinically healthy rocky mountain bighorn and domestic sheep.nasal and tonsillar samples were collected from 14 free-ranging clinically healthy rocky mountain bighorn sheep (ovis canadensis canadensis) and 10 domestic sheep (ovis aries). we identified 194 bacterial isolates, including 101 from bighorn and 93 from domestic sheep. of these isolates, 115 were gram-positive and 79 were gram-negative. staphylococcus species were the most numerous gram-positive organisms and had a higher incidence in samples from domestic than from bighorn sheep. in contrast st ...19948151809
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. ...200314567214
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 ...200314733287
