Bacteriological and clinical studies in twenty adult patients with non-tuberculous thoracic empyema, during the past ten years from November 1972 to October 1981, are reported.<BR>Anaerobes were the exclusive pathogens in 4 (20%) of 20 cases, and anaerobes together with aerobic or facultative bacteria were recovered in 8 (40%). An average of 2.5 and 3.8 (2.4 of which were anaerobic) organisms were recovered respectively. A single species of aerobe was isolated in 6, and no organism was isolated in 2 cases.<BR>Total isolates from 18 cases were 50 strains, 29 of which were anaerobic. The predominant organisms, in order of pervalence, were Bacteroides sp. (10 strains), Peptostreptococcus sp. (8), microaerophilic streptococci (6) and Fusobacterium sp. (3).<BR>Putrid odor of pleural fluid was observed in 11 (92%) of 12 cases with anaerobes, but not in any aerobic or culture-negative case. Accumulation of gas in pleural space was showed in 7 (58%) of 12 cases with anaerobes. On the other hand, gas was showed neither in cases with aerobe nor in culture-negative cases, except for one with bronchopleural fistula.<BR>These results indicate that anaerobes play an important role in most cases of pleural empyema, and therefore anaerobic culture is always necessary for bacteriological diagnosis and better antimicrobial selection. Putrid odor of pleural fluid and accumulation of gas in pleural space are reliable clinical findings for presumptive diagnosis of anaerobic empyema, before taking information of anaerobic culture.
