Exploration of the mutations of genomic ampD from the clinical isolates producing ampC β-lactamases

This article reviews the classification and β-lactam antibiotics-resistant mechanism for producing ESBLs and AmpC β-lactamases from Escherichia coli.

OBJECTIVE To investigate the productive rate of AmpC β-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital.

RESULTS The AmpC β-lactamase was detected in 35 isolates of Enterobacteriaceae(accounted for 33.
