In vitro susceptibilities of Aeromonas hydrophila against new antibiotics

Abstract

The antibiotic susceptibilities of 16 clinical isolates of Aeromonas hydrophila obtained from cancer patients with septicemia were studied. Of the new beta-lactam antibiotics tested, azthreonam and moxalactam were the most active, followed by cefoperazone, cefotaxime, and ceftizoxime. Excellent activity was demonstrated by chloroamphenicol, tetracycline, aminoglycosides, and trimethoprim-sulfamethoxazole. Semisynthetic penicillins had no appreciable activity against this organism.
