The inter‐ and intrageneric relationships of the genus Yersinia were investigated by sequence analysis of the 16S rRNA gene. A stretch of approximately 1450 nucleotides was sequenced from representatives of ten of the eleven validly described species. Phylogenetic analysis revealed that yersinae form a coherent cluster within the gamma subgroup of Proteobacteria . The intrageneric relationship was characterized by five sublines with Y. enterocolitica, Y. rohdei , and Y. ruckeri forming separates sublines each represented by a single species. A separate subline was formed by Y. pestis, Y. pseudotuberculosis and Y. kristensenii , while Y. molaretii, Y. intermedia, Y. bercovieri, Y. aldovae , and Y. kristensenii formed a fifth subline. The phylogenetic distinctness of the yersiniae sublines is compared to published phenotypic properties and results of DNA‐DNA similarity studies.
