title: Biotyping of Vibrio cholerae O1: time to redefine the scheme.
abstract: Considering the recent emergence of "hybrid biotype" and "El Tor variant", we propose to redefine the biotyping scheme for Vibrio cholerae O1 serogroup. The existing biotyping scheme has limitations and causes confusion as many of the hybrid biotype and El Tor variant strains have phenotypic and genetic changes. A revised biotyping scheme will play a significant role to understand the ecology, epidemiology and nature of infection of V. cholerae O1 strains in future.
