Distribution of protein clusters across Y. enterocolitica 8081, Y. pestis CO92, and Y. pseudotuberculosis IP32953. (a) The Venn diagram shows the number of protein clusters unique or shared between the two other high virulence Yersinia species (see Materials and methods). (b) The number of shared and unique clusters that do not contain a single member of the eight low human virulence genomes sequenced in this study.
