Mutations in ampD cause hyperproduction of AmpC and CmcB β-lactamases and high resistance to β-lactam antibiotics in Chromobacterium violaceum

ABSTRACT Bacterial resistance to β-lactam antibiotics mediated by β-lactamase enzymes is widespread worldwide. Chromobacterium violaceum, an environmental Gram-negative bacterial pathogen, is intrinsically resistant to some β-lactam antibiotics. In this work, we found that mutations in an ampD gene,...
