Abstract
Over 200 anaerobic bacterial isolates were recovered in a veterinary diagnostic laboratory from nonspecific infectious disease from 72 specimens originating from 10 animals species [cow, horse, dog, cat, pig, goat, rabbit, deer, turtle and muskrat]. The majority of isolates were non-sporeforming bacteria and about half were identified to species. Bacteroides spp. formed the major group and included B. oralis, B. fragilis, B. corrodens [B. ureolyticus], B. ruminicola ruminicola, B. r. brevis and various subspecies of B. melaninogenicus. Gram-positive anaerobic cocci constituted the next major group of isolates and the main species identified in cattle was Peptococcus indolicus. Clostridial species were uncommon. Nine specimens yielded a pure culture of an anaerobe and, in samples containing mixtures of bacterial species, each specimen yielded an average of 3.1 anaerobic and 1.4 aerobic bacterial. The failure to identify many of the isolates is discussed.
