Figure 3. Comparison of the Stx2e prophages of wild boar Escherichia coli O139:H1 strain W13-16 and pig E. coli O139:H1 P15-25 and O141:H4 P13-6 strains from France. The genes are represented with arrows color coded by function. The 2 regions present in prophage Stx2e_P136 but absent in the 2 other prophages are indicated by numbers 1 and 2. The areas between the genetic maps are shaded in blue, with a color intensity depending on the percentage of identity between each region compared. Strain name, pathotype, sequence type, serotype, and country of isolation are indicated at the right of each map. The GC skew (negative, blue; positive, red) is indicated at the top. ETEC, enterotoxigenic Escherichia coli; ST, sequence type; STEC, Shiga toxin–producing Escherichia coli.
