Maximum-likelihood tree of clinical and environmental Vibrio cholerae O1 strains, Nigeria, 2008–2015. The best evolutionary model was Kimura 3-parameter plus ascertainment bias correction plus FreeRate model 2, selected by Bayesian information criterion. The highlighted clusters represent genomes from Afr9 (blue) and Afr12 (pink) lineages. To the right of the genome name is information about source of isolation (red, human; blue, environment), year of isolation, presence of ctxAB genes (dark green block), and complete TCP cluster (light green circle). Red dots on branches represent >70% bootstrap values. Available GenBank accession numbers are provided. CTX, cholera toxin; TCP, toxin coregulated pilus.
