Stool: Yersinia enterocolitica – Shipped February 2012
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
- 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.
- Antimicrobial susceptibility testing is generally not necessary as most gastrointestinal infections with Yersinia are usually self limiting.
