Bacteriology of bronchial secretions in non-tubercular lower respiratory tract infections.
Fifty samples of bronchial secretions collected from patients of non-tubercular lower respiratory tract infections through fiberoptic bronchoscopy (FOB) were cultured both for aerobic and anaerobic organisms. Thirty-three (66%) samples yielded bacteria. Out of these, thirty were isolated in pure culture and from three, a mixed growth of aerobic and anaerobic micro-organisms was obtained. Aerobic bacteria were the predominant isolates. Stephylococcus aureus (10), pseudomonas (9) and streptococcus pneumoniae (8) were the major aerobic isolates. Ciprofloxacin was found to be the most effective drug against aerobes and metronidazole against anaerobes in vitro susceptibility tests.
