Abstract:
In the present study, a total of sixteen Proteus mirabilis isolates were recovered from 80 samples comprising of chicken (8 isolates from 25 samples), pork (2 isolate from 10 samples) and chicken cloacal swabs (6 isolates from 45 samples). The isolates were confirmed by standard cultural and biochemical tests. Antibiotic Sensitivity test (ABST) of Proteus mirabilis isolates performed by disc diffusion method revealed resistance pattern to broad spectrum of antibiotics viz. tetracycline (100%), amoxicillin-clavulanic acid (45%), cefotaxim (12.5%), gentamicin (38%) and ciprofloxacin (44%). The β-lactamase genes TEM (800 bp), CTXM-gp2 (404 bp), CTXM-gp9 (561 bp) and ACC (346 bp) were detected in six, seven, one and four isolates, respectively out of sixteen isolates of Proteus mirabilis by PCR. The high level of antimicrobial resistance of Proteus mirabilis isolated from pigs and chicken may pose a potential threat to food safety and public health.
