Simplified Phenotypic Scheme Evaluated by 16S rRNA Sequencing for Differentiation between Yersinia enterocolitica and Y. enterocolitica -Like species

Abstract
Many clinical laboratories are familiar with a sizeable group of “unserotypeable Yersinia enterocolitica ” strains. Due to identification problems, this group may hide Y. bercovieri , Y. mollaretii , and Y. rohdei strains. We present a simple scheme to distinguish between pathogenic Y. enterocolitica and potentially nonpathogenic Y. enterocolitica- like strains.
