Abstract

In the present study, 80 broiler intestinal samples obtained from retail poultry outlets of Satara from Sept to Dec 2020 were analyzed by standard microbiological methods for the isolation of Escherichia coli (E. coli). E. coli were isolated and identified based on characteristic colonies on selective agar and further confirmed by PCR. E. coli were isolated from 37.5% (30/80) of samples. These isolates were tested for their antibiotic sensitivity against 8 different antibiotics using Kirby-Bauer disc diffusion method. It showed that E. coli isolates were susceptible to Cephoxitin (90%), Cefoperazone (90%), Tobramycin (87%), Piperacillin/Tazobactam (87%), and Norfloxacin (87%). The isolates were resistant to Augmentin (93.3%), Imipenem (90%), and Nalidixic acid (66.7%). Further, multidrug resistance was observed in 20 per cent of the isolates.
