In the present study, 25 diarrheic faecal samples/ rectal swabs collected from post weaning pigs were examined by cultural method for the presence of Enterobacteriaceae members which resulted in isolation of 18 lactose fermenter and two non-lactose fermenter bacterial colonies. The recovered colonies were subjected to VITEK®2 Compact System for the identification of bacteria. Out of 18 lactose fermenter bacterial colonies, 15 were identified as Escherichia coli, two as Enterobacter asburiae, and one as Klebsiella pneumoniae. Both the lactose non-fermenter bacterial colonies were identified as Pseudomonas aeruginosa. In-vitro antibiotic sensitivity pattern of E. coli isolates showed 100% sensitivity to chloramphenicol, gentamicin and ampicillin/sulbactam whereas 60% isolates were found to be resistant to co-trimoxazole and 53% isolates to amoxicillin clavulanate and cefotaxime. All E. coli isolates showed resistance to more than four antibiotics, four isolates showed resistance to six antibiotics and two isolates showed resistance to more than seven antibiotics. Isolates of K. pneumoniae, Enterobacter asburiae and P. aeruginosa found to be sensitive to most of the antibiotics tested; whereas these isolates showed resistance to amoxycillin/clavulanate and co-trimoxazole. This study helps in assessment of bacterial resistance of enteric bacteria recovered from diarrheic pigs.
