Quantitative bacteriology of 200 sputa from patients with chronic bronchopulmonary disorders was carried out. Mycobacterium tuberculosis was the most frequently isolated pathogen (19%), followed by Streptococcus pneumoniae (13.6%), Haemophilus influennzae (9.0%), Staphylococcus aureus (7%), Klebsiella pneumonia (4%), Pseudomonas aeruginosa (4%), Escherichia coli (4%), Nocardia asteroides in association with others (6.5%), Neisseria catarrhalis (1%), and Peptostreptococcus sp. (1%). 52% of the infections were caused by single aetiologic agents while 32% were polymicrobial.
