A comparative study among clinical and environmental isolates of Vibrio cholerae at their antibiotic resistance and plasmid profile

in this study, the comparison of the antibiogram and molecular level among different serotype of clinical and environmental isolates of V. cholerae was done. Antibiogram of five clinical and three environmental isolates showed high susceptibility to all tested antibiotics, but non-O1 serotype had Ampicilin resistant. Plasmid profile screening revealed that V. cholerae O1 isolates and non-O1 Dial131 had no small size plasmid while non-O1 ab, 1J, 1R harbored three different small size plasmids with different appearance profile, two mega plasmids detected in the O1 isolate and only one mega plasmid resolute in non-O1 clinical and environmental isolates.
