The role of plasmids in the spread of antibiotic resistance needs to be explored further in E. coli of porcine origin as limited no of studies have investigated the presence of plasmid and replicon types in porcine E.coli isolates. The prevalence of porcine E. coli was determined in both healthy and diarrheic pigs in the current study. The prevalence rate of 65.21% was found in diarrhoeic pigs where as only 18.36 percent of prevalence rate was observed in healthy pigs. The antmicrobial susceptibility test was conducted on 33 E. coli isolates. The antibiogram pattern of isolated E.coli revealed highest antibiotic sensitivity to Ciprofloxacin (27.27%) followed by Enrofloxacin (24.24%), where as complete resistance was observed to Amoxycillin/Cloxacillin combination. The resistance was also recorded against Penicillin (96.97%) & Ampicillin /Cloxacillin(94%). Plasmid profile analysis was carried out on 33 porcine E.coli isolates out of which 15 isolates revealed possession of plasmids indicating 45.45% prevalence of plasmid bearing porcine E.coli isolates. The variation in number and size of plasmids was found in these isolates.
