摘要
为了解蓝舌病(BT)在我国的流行和分布情况,本试验采用竞争酶联免疫吸附法(C-ELISA)对我国重庆、新疆、西藏、湖北、河北、广西、贵州、内蒙古、吉林、辽宁、四川、云南共12个省区的19237份血清进行检测。结果显示,被调查地区均存在蓝舌病病毒(BTV)的流行,平均阳性率为4.33%~38.14%,且血清阳性率具有明显的地域性和季节性,低纬度地区的血清阳性率普遍高于高纬度地区(4.33%~38.14%),以第3季度(7~9月)阳性率最高(23.3%~46.7%),第1季度(1~3月)阳性率最低(0~13.3%),说明BTV的流行与虫媒的活动密切相关。本试验开展的BTV血清学调查,明确了蓝舌病在被调查地区的流行情况,也为蓝舌病的监测和预防提供了可靠参考。
To investigate the epidemic distribution of Bluetongue(BT)in China,a total of 19237 sera derived from 12 provinces were detected for the seroprevalence of the BTV by C-ELISA test.The results showed that all the provinces surveyed had the popularity of BTV,and the seropositive rate ranged from 4.33%to 38.14%.It’s obviously regional and seasonal.The seropositive rate increased from north to south(4.33%~38.14%).Autumn(July to September)had the highest positive rate(23.3%~46.7%)compared to other seasons,and spring(January to March)had the lowest positive rate(0%~13.3%),which indicates the prevalence of BTV is closely related to the activities of media insects.This study is the first large-scale serological survey of BTV in China,which provide the first reliable reference for BTV epidemic risk monitoring and prevention.
