Antibiotic resistance of Escherichia coli isolated from retail poultry outlets of Satara (India)

Abstract

In the present study, intestinal contents of 80 broiler birds were sampled from retail poultry outlet of Satara from Sept to Dec 2020. A total of 30 Escherichia coli (E. coli) isolates were identified based on characteristic colonies on selective agar and further confirmed by PCR. These isolates were tested for their antibiotic sensitivity against 8 different antibiotics using the 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%) whereas, high sensitivity to Augmentin (93.3%), Imipenem (90%), and Nalidixic acid (66.7%) was also observed. Further, multidrug resistance was observed in 20 percent of the isolates.
