Test ID: YERSC    
Yersinia Culture, Feces

Useful For Suggests clinical disorders or settings where the test may be helpful

Determining whether Yersinia species may be the cause of diarrhea


Reflexive testing for Yersinia species from nucleic acid amplification test-positive feces


This test is generally not useful for patients hospitalized more than 3 days because the yield from specimens from these patients is very low, as is the likelihood of identifying a pathogen that has not been detected previously.


This test provides evidence of the presence of the bacterium, Yersinia species, in feces, in a viable state, and provides an isolate for antibacterial susceptibility testing and, if needed, submission to a health department.


Minnesota healthcare providers are required to report all confirmed or suspected cases of enteric yersiniosis to the Minnesota Department of Health. Mayo Clinic Laboratories clients should refer to their local health departments regarding public health submission of Yersinia isolates.
