Abstract excerpt
Mutations within the structural gene of ampD can lead to AmpC overproduction and increases in beta-lactam MICs in organisms with an inducible ampC. However, identification of mutations alone cannot predict the impact that those mutations have on AmpD function. Therefore, a model system was designed to determine the effect of ampD mutations on ceftazidime MICs using an AmpD(-) mutant Escherichia coli strain which...
