AmpC induction by imipenem in Pseudomonas aeruginosa occurs in the absence of OprD and impacts imipenem/relebactam susceptibility

ABSTRACT In the United States, carbapenem resistance in Pseudomonas aeruginosa is linked to the regulation of chromosomal resistance determinants, AmpC and OprD. The β-lactamase AmpC requires overexpression and genetic modifications to be capable of inhibiting imipenem activity. The outer membrane p...
