Prevalence of gram negative anaerobic bacilli in routine clinical specimens.
A total of 206 gram negative anaerobic bacilli were isolated from 2591 routine clinical specimens. Majority of them (78.2%) were part of a mixed flora. A high incidence of gram negative anaerobic bacilli was found in post-operative wound infections and diabetic foot infections (30.1%), followed by necrotizing fasciitis and crush injuries (18%), pus of empyema and lung abscesses (14.5%) and aspirates from other deep abscesses (10.7%). Bacteroides fragilis was the most frequently recognized species (42.2%), followed by Fusobacterium sp. (17.4%), Prevotella sp. (15.1%) and Porphyromonas sp. (11.2%). Neomycin blood agar plate yielded the maximum number (72.8%) of strains in pure culture. Gram negative anaerobic bacilli in infective processes are significantly on the rise and so suspected cultures should be processed for both aerobic and anaerobic organisms.
