The species were identified using conventional biochemical tests, and their susceptibility to antimicrobial drugs was assessed by antibiogram Kirby-Bauer method , using the performance standards published by the Clinical and Laboratory Standards Institute. Beta-lactam-resistant genes were detected using an enhanced polymerase chain reaction assay. They presented the following phenotypes: extended-spectrum beta-lactamase ESBL , Further characterization of the first two phenotypes yielded the following breakdown of types: SHV,
