Of 3,133 clinical specimens obtained from domestic animals, 26% contained species of bacteria that were obligate anaerobes. Members of the genera Bacteroides, Fusobacterium, and Peptostreptococcus accounted for 77% of the isolates. On the average, 2 species of obligate anaerobes were found in each specimen, usually admixed with facultatively anaerobic bacteria. Of those specimens containing an obligate anaerobe, 20% contained one isolate that was resistant to penicillin, ampicillin, and cephalothin. These resistant isolates belonged to the genus Bacteroides, the most common being Bacteroides fragilis. Approximately one third of these penicillin-resistant isolates was resistant to tetracycline as well. All isolates were susceptible to chloramphenicol, tetracycline (excluding penicillin-resistant Bacteroides), metronidazole, and clindamycin.
从家畜身上采集的3133份临床样本中，26%含有专性厌氧菌。拟杆菌属、梭杆菌属和消化链球菌属成员占分离菌的77%。每个样本平均发现2种专性厌氧菌，通常与兼性厌氧菌混合存在。在含有专性厌氧菌的样本中，20%含有一株对青霉素、氨苄青霉素和头孢菌素耐药的分离菌。这些耐药分离菌属于拟杆菌属，最常见的是脆弱拟杆菌。这些耐青霉素分离菌中约三分之一也对四环素耐药。所有分离菌对氯霉素、四环素（不包括耐青霉素的拟杆菌）、甲硝唑和克林霉素敏感。
