Chemotherapy of experimental (murine) Clostridium perfringens type A gas gangrene.

Five antimicrobial drugs (ciprofloxacin, clindamycin, imipenem, penicillin G, and rifampin) were examined for therapeutic efficacy in a murine model gas gangrene due to Clostridium perfringens type A, following infection with large bacterial inocula. Imipenem was effective against all 6 strains of C. perfringens; conversely, penicillin G failed against these 6 strains. Ciprofloxacin, clindamycin, and rifampin occupied intermediate positions.
