Placentomes were extracted from the uteri of 22 aborted cows and examined to detect the cause of abortion; fetuses or fetal abomasal contents from 15 of the cows were also examined. Firm diagnoses of Pasteurella haemolytica, Actinomyces pyogenes, Listeria monocytogenes, Bacillus licheniformis, Aspergillus fumigatus or Mortierella wolfii abortion were made in 11 cases. The histopathological lesions showed some correlation with the identity of the bacterium isolated; the lesions of mycotic abortion were distinct and characterised by a coagulative necrosis. The removal of a placentome was not followed by any observable deleterious effects.
从22头流产奶牛的子宫中取出胎盘，检查以确定流产原因；还对其中15头奶牛的胎儿或胎儿皱胃内容物进行了检查。11例确诊为溶血巴斯德菌、化脓放线菌、产单核细胞李斯特菌、地衣芽孢杆菌、烟曲霉或沃尔夫被孢霉引起的流产。组织病理学病变与分离出的细菌种类有一定相关性；霉菌性流产的病变明显，特征为凝固性坏死。取出胎盘后未观察到任何有害影响。
