Vibrio cholerae species can be divided into 2 major groups cholera-causing strains of the serogroups O1 and O139, and non-O1 V. cholerae (NOVC) [1]. Non-O1 V. cholerae (NOVC) typically does not elaborate cholera toxin. It is also antigenically distinct from the V. cholerae O1 and O139 strains, which cause epidemic cholera in many countries.
