在福建宁化已发现的斑点热疫区内进行蜱类媒介及宿主调查。分别在野鼠、野免、野猪、麂、狗、牛等宿主体表捕捉各种蜱类,用鸡胚卵黄囊感染法分离斑点热群立克次体(SFGR),用微量补结、PCR/RFLP等分子生物学技术对分离株进行鉴定。结果共查出蜱类12种,鉴定分类5000余只。麂、野鼠、野猪感染SFGR率分别为1250%、947%、5833%。从媒介、宿主、病原学上进一步证实福建存在北亚斑点热疫源地的可能性。
A tick vector and host investigation was conducted in the spotted fever zone that was found in Ninghua County, Fujian Province. Wild ticks, wild boars, wild pigs, muntjacs, dogs and cattle were collected to capture various ticks, and the spotted heat group Rickettsia (SF-GR) was isolated by the chicken yolk sac infection method. PCR / RFLP and other molecular biology techniques to identify isolates. Results Totally 12 species of ticks were identified, more than 5000 were identified. The rates of SFGR infection were 1250%, 947% and 5833% respectively in muntjac, wild rats and wild boar. From the media, host, etiology further confirmed that there is the possibility of northern Fujian spot hot spots.
