Maximum-likelihood-based phylogenetic analysis of the colibactin and yersiniabactin determinants. (a) Phylogenetic tree of the colibactin gene cluster (collapsed), and (b) phylogenetic tree of the corresponding ybt determinants (collapsed) using the genetically distant K. michiganensis strains as an outgroup [38]. Additionally, the yersiniabactin sequence type (YbST) as defined by Lam and colleagues [38] associated with individual bacterial clades is indicated. The branch colours in both trees depict the prominent bacterial sequence type of the clade.
