Yersinia Isolates 2021

Friday 2nd December 2022


Summary

Yersinia case isolate numbers were higher this year than any other year in our records.

Yersinia enterocolitica biotype 2/3 serotype O:9 continues to dominate as the causative agent of NZ yersiniosis.

Selected isolates have been sequenced as part of surge investigations and for projects such as the ESR-led, HRC-funded three-year study Unravelling the mysteries of yersiniosis commenced in 2021.  https://www.esr.cri.nz/our-research/our-science-in-action/unravelling-the-mysteries-of-yersiniosis/.

Common bioserotypes continue to be associated with specific McNally 7-gene multi locus sequence types:

Yersinia enterocolitica biotype 2/3 serotype O:9 ST12

Yersinia enterocolitica biotype 2/3 serotype O:5,27 ST14

Yersinia enterocolitica biotype 4 serotype O:3 ST18

A comprehensive review of Yersiniosis in New Zealand was published by ESR staff in Pathogens in February 2021: http://doi.org/10.3390/pathogens10020191.
