The prevalence of tick-borne and related bacteria infecting adult ticks in central Spain was assessed by molecular methods. Six areas were sampled monthly during a 2-year longitudinal study. A total of 1,038 questing and 442 feeding ticks, belonging to eight different species, were tested. The most abundant species were Hyalomma lusitanicum (54% of captures), followed by Dermacentor marginatus (23%) and Rhipicephalus sanguineus (10%). Four human pathogens, including seven Rickettsia species, Anaplasma phagocytophilum, Borrelia burgdorferi, and Francisella tularensis, were detected at percentages of 19.0, 2.2, 1.7, and 0.5, respectively, whereas Bartonella spp. was never detected. In terms of infection and tick abundance, H. lusitanicum seems to be the most significant tick species in the area, carrying three of the five agents tested, and the anthropophilic tick, D. marginatum, infected with Rickettsia spp. and F. tularensis, is the most relevant in terms of public health. The significance of these data is discussed.
通过分子方法评估了西班牙中部感染成年蜱的蜱传及相关细菌的流行情况。在一项为期两年的纵向研究中，每月对六个区域进行采样。共检测了属于八个不同物种的1038只 questing蜱和442只吸血蜱。最常见的物种是卢氏璃眼蜱（捕获量的54%），其次是边缘革蜱（23%）和血红扇头蜱（10%）。检测到四种人类病原体，包括七种立克次体物种、嗜吞噬细胞无形体、伯氏疏螺旋体和土拉弗朗西斯菌，检出率分别为19.0%、2.2%、1.7%和0.5%，而巴尔通体属从未被检测到。就感染情况和蜱的数量而言，卢氏璃眼蜱似乎是该地区最重要的蜱种，携带了所检测的五种病原体中的三种，而感染立克次体属和土拉弗朗西斯菌的嗜人血蜱边缘革蜱在公共卫生方面最为重要。讨论了这些数据的意义。
