Yersinia enterocolitica IgA antibodies

Yersinia enterocolitica is a gram negative bacterium that causes zoonoses in humans zoonotic diseases (zoonoses). It can be infected mainly by ingesting infected meat, milk, tofu or water, rarely by blood transfusion. Yersiniosis is an acute disease, characterized by diarrhea and inflammation of the lymph nodes of the mesenteric lymph nodes. As a gastrointestinal infection, the disease is not dangerous, while the development of sepsis increases the mortality rate to up to 50%. IgA antibodies appear up to two weeks after infection and disappear within a few months, sometimes years. A positive indicates a recent history of infection.
