Genome architecture of Stx (±) NSF O157:H7 and SF O157:NM. Whole chromosome BRIG analysis of the genome architecture and phage inventory of the Stx (±) strains examined and referenced to the 5,572,075 bp genome of O157:H7 strain EC4115 shown in the outermost circle. The LEE-island and phage inventory are annotated, and Stx-phages are highlighted in red. Query genomes are plotted on each circle as shown in the legend. The order of genomes on each ring reflects phylogenomic position according to the stepwise model of O157:H7 evolution. Different color codes of the circles represent clade association as shown in the legend. GC-content and GC-skew of the reference are depicted in the two innermost circles, respectively.
