自2000年以来，在中国-俄罗斯边境地区发现了类似蜱传播的立克次体的临床模式。到目前为止，关于该地区病原体种类、蜱媒流行和分布以及人间病例发病率的流行病学数据仍然很少。为了鉴定该地区发生的立克次体种类，我们调查了在选定地区采集的森林尘螨。罗氏立克次体是森林立克次体中的优势立克次体，具有ompA、ompB、GLTA和17 kDa蛋白基因。林木立克次体患病率为32.25%，无性别差异。这一结果扩大了人们对拉乌尔蒂伊及其候选媒介硬蜱地理分布的认识，表明该地区出现了对人类健康的潜在威胁。
Since the year 2000, clinical patterns resembling tick-borne rickettsioses have been noticed in China-Russia border areas. Epidemiological data regarding species of the aetiological agent, tick vector prevalence and distribution as well as incidence of human cases in the areas are still sparse to date. In order to identify Rickettsia species occurring in the areas, we investigated Dermacentor silvarum collected in the selected areas. Rickettsia raoultii was the predominant Rickettsia found in D. silvarum evident with ompA, ompB, gltA and 17 kDa protein genes. The Rickettsia prevalence in D. silvarum appeared to be 32.25 % with no sex difference. The results extend the common knowledge about the geographic distribution of R. raoultii and its candidate vector tick species, which suggest an emerged potential threat of human health in the areas.
