Abstract excerpt

We investigated the role of chromosomal beta-lactamase and the MexAB-OprM efflux system in intrinsic resistance to beta-lactams in Pseudomonas aeruginosa. Determination of the susceptibilities of a series of isogenic mutants with impaired production of the beta-lactamase and the efflux system to...
