FIG 3 .

Map of the large virulence plasmids of APEC O78-9. The outer circle shows ORFs with functional classifications. The functional classifications are indicated by colors as follows: red, plasmid replication, stabilization, and maintenance; olive, plasmid transfer; yellow, mobile genetic elements; gray, unknown function. Virulence-associated operons cva (green), iro (blue), ets (dark blue), hlyF (brown), sit (orange), iuc or iut (pink) are indicated. The second and third circles show ORFs in the forward and reverse orientations, respectively. The fourth circle shows the G+C content plot. The innermost circle shows the scale. The map was created by using GenVision from DNASTAR.
