Comparison of the accessory genome composition of wild boar Escherichia coli O139:H1 strains in France with that of E. coli O139:H1, O141:H4, O147:H4, and O138:H14 of worldwide origin. Each sign represents a strain depending on its origin (star, wild boar; circle, other hosts). The distance between the signs in a 2-dimensional space increases with the decrease in orthologous genes in common between strains represented. The signs are color coded depending on the predicted pathotype. The 28 wild boar O139:H1 strains are represented by gray stars except for 1 strain lacking sta1/stb genes, represented by a yellow star. Two additional wild boar O139:H1 strains were included in this analysis and are represented by red stars because they lacked the stx2e and sta1/stb genes (Appendix 1 Table 3); they did not belong to clade WB1 (data not shown). ETEC, enterotoxigenic Escherichia coli; STEC, Shiga toxin–producing Escherichia coli; /, neither STEC nor ETEC nor hybrid STEC–ETEC.
