CLINICAL DESCRIPTION

The most common symptoms of yersiniosis are fever and diarrhea, sometimes bloody. The disease may also be manifested by enterocolitis and acute mesenteric lymphadenitis mimicking appendicitis. Complications can include post-infectious arthritis, systemic infections and erythema nodosum. Abdominal pain is usually seen with yersiniosis caused by Y. pseudotuberculosis, while enterocolitis is more commonly seen with Y. enterocolitica. The incubation period is generally under 10 days and usually is from 3 to 7 days.
