Molecular insights into the evolution & epidemiology of Vibrio cholerae

The past few years have witnessed a resurgence in the global incidence of cholera. The increasing application of procedures employing concepts and techniques assimilated from molecular biology has provided new means of discriminating V. cholerae. Such studies are providing a wealth of critical information that has assisted the epidemiologist in tracing the spread of epidemics and has provided new insights into the evolution and origin of newer variants of V. cholerae. In this article, an effort is made to collect all the recent information and present the impact this new information has made on our understanding of V. cholerae.
