| pubmed-article:3497914 | pubmed:abstractText | Fourteen strains of Enterobacteriaceae producing Richmond & Sykes Class I beta-lactamase were studied. The ability of cefoxitin and imipenem to induce beta-lactamase production (reversible derepression) and to select stably derepressed mutants in these strains was assessed. beta-Lactamase induction by cefoxitin and imipenem was demonstrated by the disc diffusion technique in all strains. Cefoxitin selected stably derepressed mutants for all strains in broth cultures, but in an identical experiment imipenem did not. The susceptibility of each strain and its stably derepressed mutant (selected with cefoxitin) to a range of beta-lactam antibiotics was then ascertained. The stably derepressed mutants exhibited decreased susceptibility to all antibiotics tested except imipenem. The decrease in susceptibility varied between strains and between antibiotics but reached a maximum of a 256-fold decrease. The beta-lactamase activity of selected stably derepressed mutant strains showed at least a 600-fold increase in activity. Imipenem would therefore seem an appropriate choice for therapy of infections caused by this group of organisms, as it is active against derepressed mutants and unlikely to select any such strains during therapy. | lld:pubmed |
