Aerobic mouth flora of the rhesus monkey

The aerobic and facultative anaerobic mouth flora of 17 rhesus monkeys was studied qualitatively, including antibiotic susceptibilities. The organisms most often encountered were Neisseria species (19.8%), alpha haemolytic streptococci (19.8%), and Haemophilus parainfluenzae (17.2%). All Haemophilus parainfluenzae isolates were susceptible to cefoperazone. The combination of penicillin and cefoperazone may be the most appropriate initial antibiotic treatment for monkey bite injuries.
