Figure 1

A BLAST atlas [8]of Escherichia coli O104 strain 55989, compared to five other E. coli O104 isolates (inner blue circles), eleven other pathogenic E. coli strains (middle red circles), three commensal, non-pathogenic E. coli strains (turquoise circles), and three H. influenza genomes (outer violet circles). The outermost black circle represents the reference E. coli 55989 compared to itself; since only the protein encoded genes are compared, the gaps shown are due to intergenic and non-protein encoding regions of the chromosome. A full legend, listing all the strains compared is available as Additional File 1.
