Yersinia hibernica sp. nov., isolated from pig-production environments

Abstract

A Gram-stain-negative, rod-shaped strain isolated from pig-production environments was identified as a new species within the genus Yersinia using multifaceted genomic and biochemical approaches. The genome of this strain was closed using a hybrid assembly approach combining both high accuracy short read sequencing data with long read sequencing technology. Phylogenetic analysis of the 16S rRNA gene showed ~98 % similarity to Yersinia kristensenii and ~98 % similarity to Yersinia enterocolitica. Average nucleotide identity (OrthoANI) values were calculated as 85.79 % to Y. kristensenii ATCC 33638^T and 85.73 % to Y. enterocolitica ATCC 9610^T thereby providing evidence that this isolate should be considered as a novel species. The type strain is CFS1934^T (=NCTC 14222^T=LMG 31076^T).
