Anaerobic flora in trophic ulcers in leprosy patients.

Material from 108 trophic ulcers from leprosy cases were studied bacteriologically. 4 cases showed growth of pure anaerobes and 69 showed mixed growth of aerobic and anaerobic bacteria. The predominant anaerobes were Fusobacteria (41), anaerobic cocci (30) and Bacteroides (25). Clostridia were isolated only in 10 cases. Metronidazole, chloramphenicol, penicillin and ampicillin were found effective against anaerobes in in-vitro studies.
