Bacteriologic investigations were carried out on a total of 142 fetuses aborted by cows. C. pyogenes, V. fetus, Streptococcus pyogenes animalis (Sofia), M. bovigenitalium, A. laidlawii, E. coli, and B. subtilis were isolated from 34 fetuses (24 per cent). Besides, single of these species were found in 80 per cent of the positive cases, and a mixed infection--in 20 per cent. The morphologic changes in all 34 fetuses that were positive were seen chiefly in the lungs and liver. Such lesions, however, were not instrumental in differentiating the etiologic agent.
对总共142头母牛流产的胎儿进行了细菌学调查。从34头胎儿（24%）中分离出化脓隐秘杆菌、胎儿弧菌、兽疫链球菌（索非亚）、牛生殖道支原体、莱氏无胆甾原体、大肠杆菌和枯草芽孢杆菌。此外，在80%的阳性病例中发现了这些物种中的单一物种，20%为混合感染。所有34头呈阳性的胎儿的形态学变化主要见于肺和肝。然而，这些病变无助于鉴别病原体。
