Phylogenetic analysis of theYersinia enterocoliticaspecies. The constructed phylogram is based on DNA sequences and rooted using the genes of Y. pestis CO92. Nine different Y. enterocolitica strains were used: IP2222 and NF-O (avirulent); 8081 and WA-314 (highly virulent); Y11, Y5307, Y8265, Y5.27P and 105.5R(r) (low virulence). The distance is scaled in units of the expected fraction of changed nucleotides.
