FIG. 1.

Venn diagrams showing core gene sets calculated with CDSs that were classified as present by GACK analysis. A core gene set of 894 CDSs for Y. enterocolitica is shown in white. Core gene sets for high-pathogenicity (path), low-pathogenicity, and nonpathogenic Y. enterocolitica strains are shown in the red (2,997 CDSs), green (1,464 CDSs), and dark blue (1,362 CDSs) circles with overlapping regions, respectively. This excludes 1,105 chromosomal and pYV CDSs that are not core to any of the biogroups.
