From 1987 to 1992,18 outbreaks of acute non-bacterial gastroenteritis occurred in Kyushu district.
The most common symptoms were diarrhea. vomiting, nausea and abdominal cramp.
Small round structured viruses (SRSVs) were detected in 52 (44.8%) of 116 stool samples from 17 outbreaks by the electron microscopy (EM) method, and a significant increase in the antibody level was noted in 42 (80.7%) of 52 paired serum samples from 12 outbreaks by the immune electron microscopy (IEM) method and in 18 (51.4%) of 35 samples from 8 outbreaks by the western blot (WB) method.
However, according to the WB method, antigen-antibody reaction was not observed to reference antigen strips (SRSV-9/Tokyo 86-510. 63 kDa) in three of the 8 outbreaks.
The detected virus was regarded as an etiologic agent for these outbreaks.
In four of 5 outbreaks which appeared associated with eating raw oysters, there was a close relation between SRSV infection and consumption of raw oysters.
