Vibrio cholerae is the causative organism of waterborne disease, cholera. V. cholerae has caused many epidemics and pandemics of cholera for many years. In this study, V. cholerae recovered from edible ice were investigated for their genetic diversity using Enterobacterial Repetitive Intergenic Consensus (ERIC) PCR and Repetitive Extragenic Palindromic (REP) PCR. Isolation was done using selective medium and the presumptive isolates were confirmed through biochemical and serological assays.
Seventy-five isolates of V. cholerae were recovered from ice samples collected from different locations of Jakarta. Specifically, 19 of them were identified as O1 serotype, 16 were Ogawa, 3 isolates were Inaba and the remaining isolates were non-O1. The fingerprinting profiles of V.cholerae isolated from ice samples were very diverse.
This result showed that the ERIC sequence is more informative and discriminative than REP sequence for analysis of V. cholerae diversity.
