Abstract excerpt
BACKGROUND: Screening methods for the detection of plasmid-mediated AmpC beta-lactamases are technically demanding. The purpose of this study was to assess screening methods for the detection of these enzymes in clinical isolates of Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis. METHODS: Isolates were selected according to a resistance phenotype consistent with production of an AmpC-type...
