摘　　要：目的调查山东地区鼠体外寄生虫分布及种类组成及鼠类自然感染恙虫病东方体(Ot)的情况。为传染病防治、媒介生物控制提供科学依据。方法采用笼日法捕鼠,收集鼠体外寄生虫,应用巢式PCR对山东地区采集的鼠类标本Ot-Sta56kDa基因片段进行检测。结果在山东省内的5市(县)中共捕获鼠类186只;采获鼠体外寄生革螨、恙螨451只,共l科3属5种。仅泰安地区黑线姬鼠脾组织中扩增出阳性结果,与血清型为Gilliam型的核苷酸序列同源性最高,为99.77%。结论山东泰安地区鼠类存在Ot自然感染,通过对山东部分地区鼠体外寄生虫分布及种类组成调查;为该地区进一步研究鼠类传染病提供了依据。Objective To investigate the species composition and distribution of parasitic mites on the rodents and infection of Orientia tsutsugamushi（Ot）,and thus to provide scientific basis for prevention of infectious diseases and medical vector.Methods The ectoparasites were collected from the rodents captured with cages.The Ot-Sta56KDa gene of rodents was identified by nested polymerase chain reaction（nPCR）.Results A total of 186 rodents were caught from five cities and counties in Shandong province,on which 451 parasitic mites belonged to 5 species,3 genera.Compared with the sequences of Ot registered in GenBank,the Ot-Sta56 nucleotide sequences shared 99.77% homology with Gilliam strain.Conclusion Natural Ot infection exists in rodents from Tai’an.
