Antibiotic Susceptibility and Genetic Analysis of Vibrio Species Isolated from Reverine Environment

The resistance profile and its correlation with mobile genetic elements were investigated in 11 Vibrio cholerae, 10 V. parahaemolyticus, 12 V. vulnificus, 11 V. fischeri, 10 V. proteolyticus and 5 V. mimicus isolated from River Narmada. All the 59 isolates of Vibrio species were examined for their susceptibility/resistance against 14 commonly used antibiotics against Vibrio species. More than 50% isolates showed resistance against five commonly used antibiotics viz., ampicillin, ceftadizime, erythromycin, chloramphenicol, cefuroxime. Plasmid of 6 kb was detected in 11 resistant isolates and class 1 integron was detected in 16 resistant isolates. SXT element was not found among resistant isolates. The present study indicated that plasmid and Class 1 integron mainly contributed to the circulation of multidrug resistance determinants in Vibrio species isolated from river Narmada.
