Figure 6

Phylogenetic comparisons of mutS among E. coli strains of different pathotypes, host origin, sequence type (ST) and phylogenetic group. The coloured letters indicate discordance between the clustering of mutS gene and the phylogenetic background of the strains. For a better overview, strains with identical mutS allele, ST, phylotype, and pathotype are not shown here. A full picture of the comparison of mutS and concatenated MLST allele sequences which contains all 177 strains is provided as additional file (Additional file 3).
