beta-Lactamases and beta-lactam resistance in Escherichia coli

G A Jacoby et al. Antimicrob Agents Chemother. 1985 Nov.

Abstract

Escherichia coli strains determining 17 different plasmid-determined beta-lactamases were tested for resistance to new broad-spectrum beta-lactam antibiotics. Several beta-lactamases demonstrated enhanced resistance to cefamandole but only low-level resistance to other agents. High production of cloned E. coli chromosomal beta-lactamase, however, provided resistance to cefamandole, cefoxitin, cefotaxime, ceftazidime, and aztreonam but not to BMY-28142 or imipenem.
