  • Multiple factors have been identified as elements of the respiratory disease complex in Rocky Mountain bighorn sheep (Ovis canadensis canadensis). (ibimapublishing.com)
  • We hypothesized that differences in health factors and Pasteurellaceae in the upper respiratory tracts could exist between populations of bighorn sheep with and without histories of pneumonic epizootics. (ibimapublishing.com)
  • We evaluated bighorn sheep in the Big Creek area of Central Idaho which had a history of respiratory disease, and hunter-harvested bighorn sheep from the Montana Spanish Peaks Range which had no history of respiratory disease. (ibimapublishing.com)
  • Low serum antibody titers against bovine viral diarrhea, and bovine respiratory syncytial virus were detected in Idaho bighorn sheep following a pneumonic epizootic and in both herds against parainfluenza-3 virus. (ibimapublishing.com)
  • Respiratory disease has been a major mortality factor in Rocky Mountain bighorn sheep (Ovis canadensis canadensis) populations in North America and has been implicated as the major cause of population declines since the 1800's (Rush, 1927, Beuchner, 1960, Post 1962, Stelfox, 1971, Schwantje, 1988).

  • Bacteria in the family Pasteurellaceae, primarily Mannheimia (Pasteurella) haemolytica, Bibersteinia trehalosi, and P. multocida have been implicated as critical pathogens associated with pneumonic epizootics in bighorn sheep (Schwantje, 1988, Rudolph et al. (ibimapublishing.com)
  • Factors in addition to Pasteurellaceae are thought to contribute to the development of pneumonia in bighorn sheep. (ibimapublishing.com)
  • In most instances, investigation into herd health takes place after a die-off of bighorn sheep becomes evident as a means to diagnose and chronicle the course of the disease. (ibimapublishing.com)
