Bacteriological study of Chronic Otitis media

A Bacteriological Study of Chronic Otitis media was carried out with special attention to anaerobes. Total number of 80 cases were studied. Sixty-nine (86.2 per cent) of the samples were positive for aerobes and twenty four (30.0 per cent) were for unaerobes. Five (6,2 per cent) cases yielded pure unaerobes and 7.5 per cent (6) of the cases did not show any organism in their samples. Pseudomonas aeruginosa was the predominant aerobe while Bacteroides melaninogenicus was the commonest anaerobe recovered Need for inclusion of antimicrobials against anaerobes in the treatment of CSOM is stressed.
