Whole-genome neighbor-joining tree of Vibrio cholerae isolate from cholera outbreak in Haiti, fall 2010; concurrent clinical isolates with pulsed-field gel electrophoresis pattern-matched combinations; reference isolates sequenced in this study; and available reference sequences. Sequence alignments of quality draft or complete genomes were performed by using Progressive Mauve (16) and visualized by using PhyML version 3.0 (17). Whole-genome relationship of Haiti isolates with closest genetic relatives is shown in the inset. Scale bar indicates nucleotides substitutions per site.
