Comparison of plasmids carrying the enterotoxin and sepA virulence genes of the wild boar Escherichia coli O139:H1 strain W13-16 and pig E. coli O141:H4 P13-6 and O9:H21 CV839-15 strains from France. The genes are represented with arrows color coded by function. The areas between the genetic maps are shaded in blue or gray for regions oriented in the same or opposite direction, respectively, with a color intensity depending on the percentage of similarity 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.
