为了解蓝舌病病毒（BTV）在山西省的感染及分布情况，采用竞争ELISA方法，对2013年和2015年的5—6月份采自山西省11个市的1090份牛羊血清样品进行了BTV抗体检测，分析BTV阳性分布与地理、气候因素的关系。结果共检测出BTV抗体阳性样品127份，总阳性率为11.65%。其中，羊阳性血清96份，阳性率为19.28%（96/498）；牛阳性血清31份，阳性率为5.24%（31/592）。结果表明，山西省部分地区牛羊群中存在BTV感染，且阳性率与纬度、降雨量有关。%To investigate the infection and distribution of the bluetongue virus(BTV)in Shanxi province,a total of 1 090 cattle and sheep serum samples were collected from 11 areas from May to June in 2013 and 2015,respectively, the BTV antibodies in the serum samples were detected with competitive ELISA. The correlation between the climate, geography factors and seroprevalence distribution was also analyzed. The results showed that the positive samples were 127,the total positive rate was 11.65%. The positive rate of sheep was 19.28%(96/498),that of cattle was 5.24%(31/592). The results suggested that the prevalence of bluetongue in cattle and sheep had already occurred in parts of Shanxi province,and the positive rate was largely influenced by the latitude and rainfall.
