[Aerobic and anaerobic bacterial flora as a cause of lower respiratory tract infection].

Bronchial aspirates collected from a group of 100 patients with respiratory infections undergoing broncho-fiberscopic examination have been tested bacteriologically. Twenty five patients was suffered from bronchopneumonia, 35 patients have had acute bronchitis, and 40 patients chronic bronchitis. Aerobic bacterial flora has been detected in 15% of patients, anaerobic flora in 13%, an mixed bacterial flora in 20%, totally in 48% of cases. Aerobic bacteria predominated in pneumonia. Bacteroides melaningogenicus prevailed in anaerobic flora. The tests of bacterial sensitivity to antibiotics have shown high sensitivity to cefotaxime, cefamandole, metronidazole, and rifampicin.
