[Presentation of a case of severe abdominal infection caused by anaerobic bacteria].

The problem of surgical infections is discussed, special attention being paid to the commonest bacterial agents, particularly those extremely serious forms induced by gram negative and anaerobic microorganisms. After an introduction regarding isolation methods and respective therapeutic programmes, attention is turned to the case of a young woman observed after an operation for perforated appendicular abscess later complicated by stercoraceous peritonitis. After initial antibiotic treatment, which was without effect, an association comprising Clindamycin, penicillin and gentamycin was employed. In just a few days this led complete remission of symptoms.
