Abstract
Intestinal obstruction is an uncommon complication of Yersinia enterocolitica infection. We report a case of enterocolitis in an 11-month-old infant, complicated by intestinal obstruction. Y. entercolitica serotype O:21, previously reported to cause severe disease, was isolated from the patient's stool. Unusual or complicated presentations of yersiniosis may be associated with more pathogenic strains of Y. enterocolitica.
