Antimicrobial susceptibility patterns of anaerobic bacteria identified from clinical specimens of diseased dogs and cats.

ABSTRACT: We aimed to clarify antimicrobial susceptibility patterns of anaerobes from diseased companion animals. Bacterial identification was based on the Japanese 2012 guidelines for the testing of anaerobic bacteria. AST was performed using the broth microdilution method. The anaerobe-containing samples collected from 2014 to 2018 included blood (anaerobe recovery rate, 5.0%), bile (9.4%), joint fluids (0.6%), pleural effusions (42.6%), ascites (64.1%), cerebrospinal fluids (3.0%), and punctures (75.0%). The anaerobes identified included Bacteroides spp. (33.2%), Peptostreptococcus spp. (19.6%), Prevotella spp. (13.6%), Propionibacterium spp. (10.3%), Clostridium spp. (9.3%), and Fusobacterium spp. (7.5%). Bacteroides fragilis group isolates were resistant to penicillin G (100%), ampicillin (100%), cefmetazole (63.6%), ceftizoxime (90.0%), and clindamycin (40.0%). Our observations demonstrated antimicrobial susceptibility in anaerobes isolated from Japanese companion animals.
