目的青海省西宁及海东市藏系绵羊血清鼠疫FI抗体检测,了解当地藏系绵羊鼠疫流行情况。方法应用鼠疫间接血凝和鼠疫胶体金2种方法对该地区藏系绵羊血清进行鼠疫Fl抗体检测。结果 IHA和GICA方法分别对所采集2301份藏羊血清进行检测,均检出鼠疫Fl抗体阳性血清3份,其中滴度1:20的1份,l:40的2份,阳性率为1.3‰。结论该地区检出鼠疫Fl抗体阳性的藏羊血清,具有通过输入藏羊而传播鼠疫的风险,应加强藏羊鼠疫的监测工作。
Objective To detect the FI antibody of Tibetan sheep in Tibetan sheep in Xining and Haidong Qinghai Province to understand the prevalence of Tibetan plague in Tibet. Methods Two kinds of methods, indirect plague of plague and colloidal gold of plague, were used to detect the plague Fl antibody in Tibetan sheep serum in this area. Results The IHA and GICA methods were used to detect 2301 Tibetan sheep serum samples collected, respectively, were detected in the plague antibody-positive serum of 3, 1 in which 1:20 titer, l: 40 in 2, the positive rate of 1.3 ‰ . Conclusion Tibetan sheep serum positive for plague Fl antibody is detected in this area, which has the risk of transmitting plague through the feeding of Tibetan sheep.
