Reactive arthritis associated with Yersinia enterocolitica gastroenteritis.

Reactive arthritis associated with Yersinia enterocolitis in adults has not been reported in this country. We are reporting a 26-year old female with a polyarticular arthritis, primarily of the large joints following an episode of diarrhea. She was also observed to have erythema nodosum and erythema multiforme. Yersinia enterocolitica grew in abundance in stool culture. The clinical picture is consistent with the reactive arthritis associated with Yersinia enterocolitis.
