In vitro susceptibility of gram-negative bacilli from pediatric patients to moxalactam, cefotaxime, Ro 13-9904, and other cephalosporins

Moxalactam, Ro 13-9904, cefotaxime, cefoperazone, older cephalosporins, and four aminoglycosides were tested in vitro against 432 strains of gram-negative bacteria isolated from pediatric patients. The new drugs were uniformly active against coliform bacilli obtained from patients with meningitis and against aminoglycoside-resistant coliform bacilli.
