Abstract: Escherichia coli is one of the leading cause of morbidity and mortality of poultry throughout the world, leading to remarkable economic burden. Human cases of antibiotic resistance has been recently linked to drug resistant animal source bacteria, which have drawn more attention towards poultry industry in particular. The present study was conducted on broiler population to isolate and identify the bacteria from clinical cases, followed by antibiotic study. A total of 24 isolates out of 68 liver and blood samples were successfully detected. Maximum resistance was found against enrofloxacin (86.3%), oxytetracycline (75%) and norfloxacin (66.7%). Whereas sensitivity was found maximum against chloramphenicol (95.8%) and streptomycin (87.5%) followed by amoxicillin, amikacin and cephalexin, making them available for use in treatment and control of the disease.
