title: Four Sporadic Pediatric Cases of Yersinia enterocolitica O:8 Infection in a Rural Area of Japan.
abstract: In the spring of 2015, we experienced a cluster of 4 sporadic cases of yersiniosis in children in Nagano prefecture, a rural area of Japan. Two patients developed appendicitis-like episodes; one had acute gastroenteritis, and the other had bacteremia associated with liver abscess. The causative agent of these infections was Yersinia enterocolitica serogroup O:8. None of the patients had an underlying illness, and all have recovered completely. The patients were neither socially nor geographically related to each other. These 4 consecutive cases suggest that Y. enterocolitica O:8 has spread substantially in the middle part of Japan, and that this virulent strain might be more common than previously reported in our country.
