Regions of the STEC O157 genome (Sakai reference strain) targeted for polymorphism validation. Black rectangles represent known phage or phage remnant integrations (Sakai prophages; Sp1-18, [4]) that were not queried for polymorphism validation. All other regions, totaling 87.8% of the genome, were included for polymorphism validation. The triangle points to nucleotide 1 of the Sakai genome sequence [GenBank:NC_002695].
