Detection of genes mediating beta-lactamase production in isolates of enterobacteria recovered from wild pets in Saudi Arabia

Abstract

Aim: To determine the genetic basis and types of beta-lactamase encountered among enterobacterial isolates of wild pets from the animal exhibit. Materials and Methods: A total of 17 beta-lactamase-producing enterobacteria recovered from fecal samples of wild pet animals were analyzed for a selected beta-lactamase gene by polymerase chain reaction. Results: Molecular analysis identified one or more β-lactamase-encoding genes in 14 enterobacterial isolates as a single or gene combination. The most frequent extended-spectrum β-lactamases types were TEM and CTX-M, and the most common AmpC enzymes were CMY-2 and DHA types. Conclusions: The study is the first in Saudi Arabia, have established the presence of β-lactamase-encoding genes in the fecal isolates of wild pets.
