FIG 2 .

Genome comparison between E. coli O78-9, different APEC strains, and E. coli K-12 MG1655. The circles from outside to inside: O78-9; O78:H9-ST23 strains c7122, IMT 2125, and NC21063; and E. coli K-12 strain MG1655. Conserved and variable regions were detected in the genomes of the different APEC strains. E. coli O78-9 was used as a reference. The chromosomal localization of regions specific for APEC O78-9 (islands and prophages) have been indicated. The map was created using the BLAST Ring Image Generator (BRIG) (67).
