Transtracheal aspirations were cultured in 120 sputum positive (on smear examination) patients of pulmonary tuberculosis. Concomitant non-tuberculous bacterial infection (aerobic and anaerobic) was found in 61.67%. Out of these, pure anaerobic growth was obtained in 14.86% and a mixed growth (anaerobic + aerobic) was noted in 12.16%. Predominant anaerobic isolate was bacteroides melaninogenicus (30%). All anaerobic bacterial isolates except bacteroides fragilis were found to be most sensitive to penicillin. However, metronidazole was found to be effective against most anaerobic isolates and gentamycin was ineffective against most anaerobic organisms. Patients having mucopurulent, purulent and foul smelling sputum yielded statistically higher percentage of anaerobes. Yield of anaerobes was higher in patients having far advanced and fibrocavitary tuberculosis.
