Comparison of pRS218 sequence to some virulence plasmids of other E. coli . Each code indicates a plasmid sequence. From top to bottom; pRS218, pUTI89 (a plasmid of the acute cystitis causing E. coli strain UTI89), pEC14_114 (a plasmid of the uropathogenic E. coli strain EC14), pUM146 (a plasmid of the adherent invasive E. coli strain UM146), p1ESCUM (a plasmid of the acute cystitis causing E. coli strain UMN026) and pECSF1 (a plasmid of the commensal E. coli strain SE15). Each color box indicates clusters of ortholog genes present in plasmid sequences. White spaces in the blocks indicate the sequences that are not present in other plasmid sequences.
