Yersiniose (infection bactérienne)

Overview 

Yersiniosis is an infectious disease caused by bacteria from the Yersinia group, most commonly Yersinia enterocolitica. It primarily affects the intestines and can lead to symptoms like diarrhea, abdominal pain, and fever.

Yersiniosis is usually transmitted through contaminated food, especially undercooked pork, or unclean water. Most cases are mild, but severe infections may require medical treatment.
