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.

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.
