Yersinia occitanica is a later heterotypic synonym of Yersinia kristensenii subsp. rochesterensis and elevation of Yersinia kristensenii subsp. rochesterensis to species status

The taxonomic position of Yersinia kristensenii subsp. rochesterensis and Yersinia occitanica was re-evaluated by genomic analy-sis. Average nucleotide identity (ANI), digital DNA?DNA hybridization values, and phylogenetic analyses of the type strains indicate that Y. kristensenii subsp. rochesterensis and Y. occitanica are the same genospecies. Additionally, the overall genomic relatedness index (OGRI) values reveal that Y. kristensenii subsp. rochesterensis should be elevated to species status as Yersinia rochesterensis sp. nov. The taxonomy of the Yersinia genus has experienced a recent expansion with the description of several new species within the past two years [1?4]. Three Yersinia species are important human zoonotic pathogens with Yersinia pestis responsible for some of the most impactful pandemics in recorded human history [5]. Yersinia enterocolitica and Yersinia pseudotuberculosis are etiological agents for the foodborne illness yersiniosis
