Abstract

Antimicrobial resistance (AMR) is a growing public health threat worldwide, and members of the Enterobacteriaceae family are among the clinically important bacteria rapidly developing resistance to available antibacterial agents. The development of extended-spectrum β-lactamase (ESBL) enzymes is the primary cause of resistance to third-generation cephalosporins among Enterobacteriaceae. Quails also represent a source of animal protein deficiency in developing countries including India. This study aimed to detect the presence of extended-spectrum β-lactamases (ESBLs) and fluoroquinolone-resistant Escherichia coli from fecal samples of quails in Puducherry. A total of 36 fecal samples of quails from six different retail outlets were collected. E. coli could be isolated from 27 fecal samples and confirmed as E. coli by polymerase chain reaction by targeting the uspA gene. The isolates were preliminarily screened for ESBL production by indicator antimicrobial disc and phenotypic ESBL production was confirmed by combination disc method. The isolates were subjected to genotypic detection of ESBL (bla CTX-M, bla TEM, and bla SHV) by PCR. Out of 27 isolates, 16 isolates were positive for the presence of ESBL-producing genes, in which, 9 harbored bla CTX-M, 2 harbored bla TEM, and 5 harboured bla SHV genes. Similarly, out of 27 isolates 13 isolates were found positive for fluoroquinolone resistance in which 13 (48.18%) isolates harbored the qnrS gene, and 11 (40.74%) isolates harbored the qnrB gene. Antimicrobial susceptibility test showed that the isolates exhibited a high level of resistance against Cefpodoxime (90%), Amoxycillin/clavulanic acid (70%), Ceftriaxone (60%), Cefotaxime (55%), Ceftazidime (45%), Ciprofloxacin (40%) and Aztreonam (30%).
