Fig. 1: Phylogenetic clustering of Bangladesh V. cholerae strains.
From: Genomic attributes of Vibrio cholerae O1 responsible for 2022 massive cholera outbreak in Bangladesh
a Maximum likelihood phylogenetic tree rooted from out-group reference strain Vibrio cholerae N16961 based on whole genome SNPs and the strains belonging to lineages BD-0, BD-1, BD-1.1, BD-1.2, and BD-2. Metadata of isolates are displayed in rings according to color scheme on the left. Lineages BD-0, BD-1, BD-1.1, BD-1.2, and BD-2 are defined by blue, light green, green, orange, and red tree branches, respectively. The majority of strains isolated between 2018 and 2022 clustered with BD-1.2. b Unrooted tree showing the difference between the two subclades BD-1.1 and BD-1.2 of the clade BD-1. Genetic variant data used are provided in Source Data 1 and related metadata in Supplementary Data 1.
