Phenotypic and Molecular Characterization of Plasmid Mediated AmpC β-Lactamases among Escherichia coli, Klebsiella spp., and Proteus mirabilis Isolated from Urinary Tract Infections in Egyptian Hospitals

<table>Agarose gel electrophoresis of AmpC β-lactamase genes amplified from eight different isolates. Lanes M1 and M2 are 100 bp DNA marker. Lanes from 1 to 4 and from 6 to 9 are the amplified product of CIT gene family (500 bp). The isolate K1 is Klebsiella pneumoniae, E1-6 are E. coli isolates, and P1 is Proteus mirabilis isolate. The size of the marker in base pairs is shown on the right.</table>
