“Yersinia enterocolitica is a gram-negative bacillus shaped bacterium that causes a zoonotic disease called yersiniosis. The infection is manifested as acute diarrhea, mesenteric adenitis, terminal ileitis, and pseudoappendicitis. In rare cases, it can even cause sepsis.Infection is transferred predominantly through the fecal-oral route. Pork consumption especially undercooked or raw pork products are responsible for yersiniosis.”
