Yersinia enterocolitica osteomyelitis in a child.

Yersinia enterocolitica systemic infections are uncommon and osteomyelitis due to this organism is very rare. We report a 9-year-old girl with thalassemia major, liver cirrhosis, and hemosiderosis who developed osteomyelitis of the rib caused by Y enterocolitica type 0:3. Serologic response to the infection was confirmed. No definite source of infection was identified.
