【摘要】 采用血凝抑制试验 (HI)检测了 1998年采集的云南省 31个县市 1847份健康人血清中的辛德毕斯 (Sindbis)病毒抗体 ,阳性 35 6份 ,总阳性率为 19.2 7% ;其中健康人阳性率为 2 0 .71% (334 / 16 13) ,儿童阳性率为 1.33% (2 / 15 0 ) ,放牧人员阳性率为 49.0 3% (76 / 15 5 ) ,士兵阳性率为 2 .38% ,发热病人阳性率为 13.33% (2 0 / 15 0 ) ;不同县市抗体阳性率之间有显著差异 ,以滇西南及金沙江河谷地带较其它地区高 ,抗体阳性率与海拨、气温、无霜期有一定关系更多还原

【Abstract】 The paper showed that the antibody against Sindbis (SIN) virus was detected in 1 847 sera of people from 31 counties in Yunnan.By hemagglutination inhibiation assay, 365 sera was positive with positive rate of 19.27%,among them,the children accounted for 1.31%(2/153);the herdsmans’ 49.03%(76/155);the soldiers’ 2.38%(2/84) and fever patients’ 13.33(20/150). The highest positive rate was found in the counties of south west and the Jinsa River Valley in Yunnan.The results showed that the height above sea level, air temperature and frost free period affected the positive rate of antibody against SIN virus.更多还原
