A survey in Japan showed that of 2036 slaughtered cattle 58(3%) had abscesses in sites other than the liver. In 21 of the affected animals the lesions were pulmonary and in 32 abdominal (excluding hepatic); in five animals the lesions were found elsewhere (muscle 2, skin 2, bone 1). Nineteen (33%) of the 58 cattle also had abscesses in the liver. Obligate anaerobes alone were isolated from 17(29%) of the affected animals (Fusobacterium necrophorum 14, Bacteroides spp. 2, Peptostreptococcus anaerobius 1). A mixture of obligate anaerobes and aerobes or facultative anaerobes was isolated from 31 affected cattle: of these animals 21 yielded large and five small numbers of F. necrophorum; three yield fusobacteria other than F. necrophorum; and two yielded Propionibacterium acnes. The remaining 10 affected animals yielded only aerobes or facultative anaerobes. The numbers of viable obligate anaerobes in pus specimens were in the range 10(3)-10(9)/ml.
日本的一项调查显示，在2036头屠宰牛中，58头（3%）在肝脏以外的部位出现脓肿。在21头受影响的动物中，病变位于肺部，32头位于腹部（不包括肝脏）；在5头动物中，病变出现在其他部位（肌肉2处、皮肤2处、骨骼1处）。58头牛中有19头（33%）肝脏也有脓肿。仅从17头（29%）受影响的动物中分离出专性厌氧菌（坏死梭杆菌14株、拟杆菌属2株、厌氧消化链球菌1株）。从31头受影响的牛中分离出专性厌氧菌与需氧菌或兼性厌氧菌的混合物：在这些动物中，21头产生大量坏死梭杆菌，5头产生少量坏死梭杆菌；3头产生除坏死梭杆菌以外的梭杆菌；2头产生痤疮丙酸杆菌。其余10头受影响的动物仅产生需氧菌或兼性厌氧菌。脓标本中存活专性厌氧菌的数量范围为10(3)-10(9)/ml。
