河南省信阳市动物中新布尼亚病毒感染情况调查

Investigation of animals infected with novel bunyavirus in Xinyang City,Henan Province,China

目的了解河南省信阳市动物中新布尼亚病毒感染情况,为研究其传播途径和防治策略奠定基础。方法在信阳市商城县和光山县采集动物血液,应用荧光RT-PCR方法检测血液标本中是否携带新布尼亚病毒核酸,采用双抗原夹心ELISA方法检测新布尼亚病毒总抗体。结果在调查点采集到5种动物血清标本合计312份,结果均未检测到新布尼亚病毒核酸;141份动物血清检测到新布尼亚病毒总抗体,总体阳性率为45.19%,鼠、牛、羊、猪和狗分别为1.06%,100.00%、76.27%、3.57%和75.00%,5种动物的抗体阳性率有统计学意义。结论河南省信阳市牛、羊、狗等家养动物中存在新布尼亚病毒抗体,可能为该病毒的储存宿主。
