福建省宁化林区蜱类及宿主感染斑点热群立克次体调查

Study on the Host Animals and Transmission Vectors of SFGR in Ninghua County, Fujian

目的：１９９４～１９９７年间作者对福建宁化已发现的斑点热疫区内进行蜱类及宿主感染调查。方法：分别在鼠类、野兔、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，用微量室温补体结合、免疫萤光及ＰＣＲ／ＲＦＬＰ技术对分离株进行鉴定。结果：分类鉴定５０００余只蜱类共５属１３种。麂、鼠类、野猪斑点热群立克次体感染率分别为１２．５０％，９．４７％，５８．３３％。分别从野兔、麂体表寄生的越原血蜱中分离出斑点热群立克次体。结论：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。

OBJECTIVE To find out the hosts and transmission vectors of spotted fever group rickkettsiosis (SFGR) in Ninghua County, Fujian METHODS 13 species of Ixodiodeas were identified They were from rattus, wild boar, hare, muntiacus reevesi ogilby and dog from 1994 to1997 in endemic areas SFGR were isolated from Ixodiodeas with Embryonate hens eggs and identified with mCF,PCR/RFLP etc RESULTS The SFGR infection rates of muntiacas reevesi ogilby, wild rattus and wild boar were 12 50%, 9 47% and 58 33% respectively CONCLUSION It has been proved that Fujian may be a endemic area of North Asia Fever SFG, confirmed by host animals, transmission vectors and aetiology
