劳氏立克次体是一种新发现的蜱传病原体,属于立克次体属斑点热群中的一员,其主要引起人的蜱传淋巴结炎等疾病。劳氏立克次体目前主要发现存在欧洲和亚洲。蜱是劳氏立克次体传播媒介,革蜱的携带率最高,平均携带率高达47.74%。劳氏立克次体已在我国吉林、黑龙江、西藏、新疆、甘肃等地的蜱中检出。本文从劳氏立克次体的地理分布、传播媒介、医学重要性及分子生物学等方面研究现状做一综述。
Rickettsia raoultii, which belongs to spotted fever group Rickettsia (SFGR), is an emerging causative agent of calp eschar and neck lymphadenopathy (SENLAT), and mainly founded in Europe and Asia. R. raoultii is mainly transmitted by ticks and high prevalence in Derrnacentor spp. and the average level is up to 47.74%. R. raoultii have been detected in ticks collected from Jilin, Heilongjiang, Tibet, Xinjiang, and Gansu provinces in China. In this paper, we reviewed the geographic distribution, hio-vector, medical importance, and molecular biology of R. raoultii.
