Position of major chromosomal rearrangements in E. coli O157:H7 genomes. The relative positions of all LCRs ≥50 kb (blue lines) are marked on the chromosomal maps (grey line) of strains from lineage Ic (purple), lineage Ia (blue), lineage I/II (orange) and lineage II (green). Strains are sorted based on their phylogenetic relatedness. Chromosomes are centred by the replication terminus (Ter), beginning and ending at the origin of replication (OriC). LCRs are shown relative to four reference strains: (a) 9000, lineage Ic; (b) Sakai, lineage Ia; (c) TW14359, lineage I/II; (d) 180, lineage II. The loci of non-stx prophage (red line) and prophage carrying stx1(orange), stx2c (green) and stx2a (black) are mapped for each reference strain.
