Anaerobic bacterial infections and response to treatment in dogs and cats: 36 cases (1983-1985).

Abstract

Anaerobic bacteria have been increasingly implicated as important pathogens in animals. To determine the prevalence of anaerobic bacterial infection, the results of anaerobic bacteriologic culture of 599 specimens obtained from dogs and cats hospitalized at the Colorado State University Veterinary Teaching Hospital were reviewed. Obligate anaerobic bacteria were isolated from 35% of properly submitted specimens; Bacteroides spp and Fusobacterium spp were the organisms most commonly isolated. Infections most often containing anaerobes were abscesses, pleuropulmonary infections, and abdominal infections. A complication rate of 28% was observed with anaerobic bacterial infections; failure to initially treat with an effective antibiotic increased the rate of recurrence of infection.
