Figure 1From: Phylogenetic classification of Escherichia coliO157:H7 strains of human and bovine origin using a novel set of nucleotide polymorphismsRegions 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].Back to article page
