Abstract
MICs of imipenem, cefoxitin, cefmetazole, and amoxicillin-clavulanic acid were determined against 100 strains of Mycobacterium fortuitum and 200 strains of Mycobacterium chelonae. Imipenem and cefmetazole were more active against M. fortuitum than cefoxitin was, and imipenem (which inhibited 39% of strains at 8 micrograms/ml) was the only beta-lactam active against M. chelonae subsp. chelonae.
