Figure

Maximum-likelihood tree based on an orthologous 193-nt–long high-quality orthologous single-nucleotide polymorphism (hqSNP) matrix of 75 Vibrio cholerae O1 El Tor genomes using the general time-reversible model, withestimation of invariant sites. The phylogenetic tree shows clustering of strains isolated from travel-associated cases of V. cholerae O1 El Tor (asterisks) with isolates collected worldwide. The CIRS101 genome was used as the outgroup. The numbers above nodes represent a statistical

Figure. Maximum-likelihood tree based on an orthologous 193-nt–long high-quality orthologous single-nucleotide polymorphism (hqSNP) matrix of 75 Vibrio cholerae O1 El Tor genomes using the general time-reversible model, withestimation of invariant sites. The phylogenetic tree shows clustering of strains isolated from travel-associated cases of V. cholerae O1 El Tor (asterisks) with isolates collected worldwide. The CIRS101 genome was used as the outgroup. The numbers above nodes represent a statistical branch supports calculated using PhyML (black circle). The internal node between the RND6878 isolate and the Haiti/Nepal-4 clade is labeled with the estimated most recent common ancestor date, which was predicted using BEAST (http://beast.bio.ed.ac.uk). The date range provided represents the 95% CI of the estimate. Scale bar indicates substitutions per variable site.
