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

This study identifies mutations in the ampD gene of Chromobacterium violaceum that lead to overproduction of beta-lactamases and increased resistance to beta-lactam antibiotics.

A cytochrome bd repressed by a MarR family regulator confers resistance to metals, nitric oxide, sulfide, and cyanide in Chromobacterium violaceum

This paper identifies a cytochrome bd (CioAB) in Chromobacterium violaceum that confers resistance to multiple stressors, including metals, nitric oxide, and cyanide, and shows it is regulated by a MarR family repressor and quorum sensing.
