黄冈市发热伴血小板减少综合征传播媒介蜱及宿主动物携带新型布尼亚病毒情况调查

Survey on Ticks and Host Animals of Severe fever with thrombocytopenia syndrome virus in Huanggang,Hubei Province

调查黄冈市发热伴血小板减少综合征病毒(SFTSV)在传播媒介蜱和宿主动物中的携带情况,为该传染病的防控提供基础资料。2013年4~6月,选择湖北省黄冈市两个报告SFTS疫情的行政村,采集疫区蜱及宿主动物牛、羊血清样本,用RT-PCR方法对蜱组织、牛、羊血清进行SFTSV核酸检测。共采集蜱256只,牛血清17份,羊血清8份,所采集蜱共1科4属4种,优势种为长角血蜱。蜱组织及牛、羊血清SFTSV阳性率分别为3.13%,17.65%和12.50%。黄冈市长角血蜱为优势种,蜱及家畜牛、羊均检测出SFTSV阳性,推测发热伴血小板减少综合征在自然界'宿主动物→蜱→人'传播的可能性,避免蜱叮咬是预防SFTS的关键。

Survey on ticks and host animals of Severe fever with thrombocytopenia syndrome virus in Huanggang,to provide basic data for the control and prevention of this vector-borne disease.From April to June in 2013,ticks and animal serum samples were collected from affected areas,and SFTS virus were detected by real time quantitative PCR.256 ticks were collected from grassland and livestock,after classification and identification,these collected ticks mostly classified to 4 species,71.09%for Haemaphysalis longicomis.The result of real time quantitative PCR of ticks,cattle serum and sheep serum samples showed that infection rates were 3.13%,17.65%and 12.50%,respectively.Haemaphysalis longicomis was dominated in Huanggang,the result of real time quantitative PCR indicated that,the SFTS may transmitted by"host animals→ticks→human",to avoid tick bites were the key to prevent SFTS.
