An epizootic of pneumonia in 20 captive Rocky Mountain bighorn sheep (Ovis canadensis) is described. The sheep were maintained in large paddocks for about 9 months after which, in the late summer, the entire herd died within a three week period. Large numbers of Muellerius adults, eggs and larvae were in the lungs of all sheep. First stage larvae were widely disseminated throughout the lungs and apparently elicited a granulomatous pneumonia. Pasteurella sp. and other bacteria were isolated from the lungs of several sheep but no Chlamydia, Mycoplasma or viral agents were recovered. Elevated serum fibrinogen levels and normal leukocyte values were found in blood samples taken from several sheep 7-14 days prior to death.
本文描述了20只圈养落基山大角羊（加拿大盘羊）发生的一场肺炎 epizootic 。这些羊在大围栏中饲养了约9个月，之后在夏末，整个羊群在三周内全部死亡。所有羊的肺中都有大量的缪勒属成虫、虫卵和幼虫。第一期幼虫广泛散布于整个肺部，显然引发了肉芽肿性肺炎。从几只羊的肺中分离出了巴氏杆菌属和其他细菌，但未检测到衣原体、支原体或病毒病原体。在几只羊死亡前7 - 14天采集的血样中，发现血清纤维蛋白原水平升高而白细胞值正常。
