M114-2

Stool:  Yersinia enterocolitica – Shipped February 2012

HISTORY

A sample simulating stool collected from a 38 year old female with diarrhea was sent to category A and B laboratories.

Participants were expected to isolate and report Yersinia enterocolitica. Public Health notification was also required.

MAIN EDUCATIONAL POINTS from M114-2

  1. Even though Yersinia enterocolitica is a less common pathogen causing diarrhea, stool samples should be examined for its presence. Y. enterocolitica is easily identified using commercial identification systems incubated at 25°C.
  2. Antimicrobial susceptibility testing is generally not necessary as most gastrointestinal infections with Yersinia are usually self limiting.
