M161-3

Stool: Yersinia enterocolitica – Shipped May 16, 2016

HISTORY

A simulated stool sample collected from a 25 year old patient who developed diarrhea while visiting Vancouver and reports joint pain 2 weeks later. The sample was sent to category A and B laboratories.

Participants were expected to isolate and identify Yersinia enterocolitica and report the organism to public health (PH) authorities.

MAIN EDUCATIONAL POINTS from M161-3

  1. Reports should indicate which pathogens were sought, even if not detected. The report of Yersinia enterocolitica should include also a statement that “No Salmonella, Shigella, Campylobacter, Escherichia coli O157:H7, Aeromonas or Vibrio species were isolated”.
  2. Yersiniosis, caused by Y. enterocolitica or Y. pseudotuberculosis, is a notifiable disease in most jurisdictions in Canada, but is not nationally notifiable.
