1) AmpC β-lactamases are clinically important mechanism of resistance and is an emerging threat 2) AmpC can be inbred, induced or mutated into existence 3) AmpC β-lactamases producing strains pose diagnostic and therapeutic difficulties for clinical microbiologists. Abstract and Figures. AmpC beta-lactamases are clinically important cephalosporinases encoded on the chromosomes of many of the Enterobacteriaceae and a few other organisms, where they mediate. AmpC beta-lactamases (23). AmpC beta-lactamases degrade penicillins, expanded-spectrum cephalosporins (with the ex-ception of cefepime and cefpirome), cephamycins, monobac-tams, and beta-lactam inhibitors. In contrast to expanded-spec-trum beta-lactamases (ESBLs), AmpC beta-lactamases are inhibited by boronic acid and cloxacillin (2, 9, 25). In Cited by:
