Comparison of antimicrobial-resistance genes with the phylogeny of wild boar Escherichia coli O139:H1 strains in France with those of E. coli O139:H1, O141:H4, O147:H4, and O138:H14 of worldwide origin. The tree is based on the phylogeny of the strains according to their core genome. The shapes of the leaves in the tree correspond to the origin of the strains (star, wild boars; circle, other hosts), and the colors of the leaves represent their serotype. Antimicrobial-resistance genes are grouped into different categories whose names are indicated at the top, with a color code. Scale bar indicates number of substitutions per site.
