Yersiniosis

An infectious disease that is caused by a yersinia (Y. enterocolitica) transmitted chiefly in contaminated water and food or raw or undercooked pork products and that is marked especially by fever, abdominal pain, and diarrhea.

Common symptoms in children are fever, abdominal pain, and diarrhea, which is often bloody. Symptoms typically develop 4 to 7 days after exposure and may last 1 to 3 weeks or longer.

Treament: Abscesses may require surgical drainage. Surgical exploration may be warranted if appendicitis cannot be safely ruled out. Laparotomy findings in Y enterocolitica infection usually include mesenteric lymphadenitis and terminal ileitis, with a healthy appendix.
