Fig. 1From: Genome-wide association reveals host-specific genomic traits in Escherichia coliDistribution of 1198 E. coli isolates with host species by a core-genome phylogeny and b clustering based on accessory gene content. Clades on the phylogeny represent phylogroups, the inner-ring represents host-species, and the outer ring indicates the geographical region. Each bubble in accessory gene clustering represents individual E. coli strains coloured according to phylogroupsBack to article page
