A total of 62<em> E. coli</em> isolates were recovered from poultry meat. The <em>E. coli</em> isolates belonged to different serogroups based on ‘O’ serotyping of the isolates viz O29 (10.8%), O8 (7.7%), O40 (6.15%), O2 (4.61%), O60 (3.08%), O106 (3.08%), 42 (1.54%), O 87 (1.54%), and 01 serotypes of O1, O7, O30, O45, O59, O66, O105, O1116, O136, O141, O147, O148, O166, and O172. Sixteen (24.62%) of the isolates were UT (untypable) and 6 (9.23 %) were rough types. Molecular characterisation of the isolates was performed, targeting <em>stx1</em> and <em>stx2</em> virulence gene fragment. Out of 62 <em>E. coli</em> isolates, 10 (16.12%) were carrying virulence gene <em>stx2</em>, whereas none of the isolate was carrying <em>stx1</em> gene. The <em>E. coli </em>isolates showed wide variation in resistance pattern against the antimicrobial agents that we used (9-90%). Among <em>E. coli </em>isolates, maximum resistance was observed against cefuroxime (89.1%) and penicillin (89.4%), followed by ampicillin (80.43%), vancomycin (74.1%), co-trimoxazole (73.1%), cephalothin (60.8%), ceftriaxone (28.2%), tetracycline (17.4%), gentamicin (13%), amikacin (13.04%), ofloxacin (13%), and ciprofloxacin (6.5%). A high degree of susceptibility was observed against amikacin (84.7%) and ciprofloxacin (76%) followed by gentamicin (71.73) and ofloxacin (60.86%). High multiple antibiotic resistances were observed and a total of 34 resistance patterns were identified.</span></p>}, number={3}, journal={Veterinaria Italiana}, author={Kaushik, Purushottam and Anjay, Anjay and Kumari, Savita and Dayal, Shanker and Kumar, Sunil}, year={2019}, month={Jan.}, pages={197–204} }
