Cefamandole minimum inhibitory concentrations (MICs) of 10 strains of Enterobacter were determined by the ICS agar dilution and broth dilution procedures. Agar dilution MICs ranged from 1 to 8 μg/ml, with an inoculum of 10 4 organisms/spot. Broth di

Mutants with enhanced β-lactam resistance were selected from strains of Enterobacter cloacae and E. aerogenes by using three antibiotics. High-level β-lactamase-producing mutants had similar degrees of increased resistance, enzyme substrate profile
