Core genome SNP phylogeny of toxigenic ctx (+) Vibrio cholerae serogroup O1, O139, O37, O75, and O141 strains and the NAG strain, generated using Parsnp version 1.5.2. 3566-08 served as the reference genome to build this phylogeny. Nontoxigenic ctx (−) variants of O141 and O1 were also included for comparison.
