Abstract

ABSTRACT In some enterobacterial pathogens, but not in Escherichia coli , loss-of-function mutations in the ampD gene are a common route to β-lactam antibiotic resistance. We constructed an assay system for studying mechanism(s) of enterobacterial ampD mutation using the well-developed genetics of E. coli . We integrated the Enterobacter ampRC genes into the E. coli chromosome. These cells acquire spontaneous recombination- and SOS response-independent β-lactam resistance mutations in ampD . This chromosomal system is useful for studying mutation mechanisms that promote antibiotic resistance.
