Video - Yersinia enterocolitica

Yersinia enterocolitica is a Gram-negative bacterium belonging to the Enterobacteriaceae family that causes a diarrheal illness called yersiniosis. It secretes bacterial proteins called Yops, which block the secretion of proinflammatory cytokines and inhibit macrophage activation. Yersinia enterocolitica is transmitted through pet feces, contaminated milk, or pork and causes a gastrointestinal infection that can mimic appendicitis. It can spread systemically and cause septicemia, which can be rapidly fatal if left untreated. Even after the infection, there may be associated sequelae such as reactive arthritis and erythema nodosum.
