Abstract

The management of postoperative wound infections is a major problem in hospitals due to the frequent ineffectiveness of antibiotic treatment. The objectives of this study are to identify the bacteria responsible for postoperative wound infections and to describe these antibiotic resistances in order to improve the management of these infections. It is a prospective study of 52 bacteriological results of postoperative wounds for a period of six months from January 2021 to June 2021 in the laboratory of the University Hospital of Befelatanana. This study showed 26 (50%) isolates of staphylococci, 17 (32.7%) isolates of enterobacteria, 6 (11.5%) isolates of streptococci and 3 (5.8%) isolates of nonfermenting gram-negatif bacilli. Antibiotic resistance, varies from 0% (vancomycin) to 92.3% (penicillin G) for staphylococci isolates, 0% (imipenem, amikacin) to 94.1% (amoxicillin) for enterobacteria isolates, 0% (vancomycin) to 50% (penicillin G) for streptococci isolates and 33% (imipenem, amikacin) to 100% (cotrimoxazole) for the isolates of nonfermenting gram-negatif bacilli. The knowledge of antibiotic resistance of bacteria responsible for postoperative wound infections allows better patient management.
