Yersinia Enterocolitica: Practice Essentials, Background, PathophysiologyDisease


Yersiniosis is an infection caused by the bacterium Yersinia, the same family that includes Yersinia pestis which is the bacteria responsible for causing the plague. The primary cause for yersiniosis is caused by Y. enterocolitica and is predominantly transferred through the fecal-oral consumption of infected pork, contaminated water, or contact with someone who has prepared a pork product. It is estimated to cause 117,000 infections and 35 deaths in the United States per year.
