Phylogeny and metadata summary of 105 Vibrio anguillarum isolates highlighting major lineages. (A) Maximum-Likelihood phylogeny of 105 Vibrio anguillarum strains constructed using core SNPs mapped to the reference genome ATCC 68554 (775). The colours of the terminal nodes correspond to the six major lineages, identified by PopPUNK containing a minimum of three strains. Strains from the 31 minor lineages are all shown in white. Blocks of recombination have not been removed prior to reconstruction of this tree. (B) The proportion of isolates belonging to each major lineage according to geographical source. Pie charts are weighted by number of isolates. (C) Bar graphs indicate the number of isolates found with each serotype and host / environmental source. Hosts are grouped both by species and by family.
