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.
1987年至1992年期间,九州地区发生了18起急性非细菌性肠胃炎疫情。最常见的症状为腹泻、呕吐、恶心和腹部绞痛。通过电子显微镜(EM)方法,在17起疫情的116份粪便样本中的52份(44.8%)中检测到小圆结构病毒(SRSV);通过免疫电子显微镜(IEM)方法,在12起疫情的52份配对血清样本中的42份(80.7%)中观察到抗体水平显著升高;通过蛋白质印迹法(WB),在8起疫情的35份样本中的18份(51.4%)中观察到抗体水平显著升高。然而,根据蛋白质印迹法,在8起疫情中的3起中,未观察到与参考抗原条带(SRSV-9/东京86-510,63 kDa)的抗原-抗体反应。检测到的病毒被视为这些疫情的病原体。在5起似乎与食用生牡蛎有关的疫情中,有4起SRSV感染与食用生牡蛎之间存在密切关联。
