[Detection and serotyping of HRVs collected from children with acute gastroenteritis in winter of 1986 to 1991].
Fecal samples from sporadic acute gastroenteritis patients who visited at a pediatrician during five consecutive winter seasons in Kurume City located at north part of Kyushu district. Fecal samples were subjected to detection of rotavirus and other viruses and study of yearly changes in serotype of rotavirus. The rate of group A rotavirus positives in third winter and other consecutive winters were 12.5%, 40 to 65%, respectively. 60% specimens were successfully serotyped: 58% was serotype 1.22% was serotype 3.6% was serotype 2, and 14% was serotype 4. The dominant serotype in first, fourth and fifth winter was type 1. However in second winter each serotype of rotavirus was almost equally detected. During five consecutive winters six patients visited at the same pediatrician twice more than two months interval. They all had acute gastrointestinal symptoms. In six patients rotavirus was detective just once.
