This study was carried out using Ixodes ricinus ticks collected during 2005 and 2006 from the Friuli Venezia Giulia (FVG) region in the northeastern part of Italy and an area along the Slovenian side of the western border of Italy. The results indicate that Rickettsia spp. is widely distributed throughout these areas, with the greatest prevalence in the central part of the FVG region. The prevalence of Rickettsia spp. was 4.5% during 2005 and 6.1% during 2006. By sequencing the 16S rRNA gene, we show for the first time the presence of Rickettsia helvetica in I. ricinus ticks in the FVG region and the presence of R. monacensis in ticks in both areas. Furthermore, we detected a sequence with a high homology with that of R. limoniae in a tick obtained from the alpine zone.
本研究使用了2005年和2006年期间从意大利东北部的弗留利-威尼斯朱利亚（FVG）地区以及意大利西部边境斯洛文尼亚一侧的一个区域采集的蓖麻硬蜱进行。结果表明，立克次氏体属在这些地区广泛分布，在FVG地区中部的患病率最高。2005年立克次氏体属的患病率为4.5%，2006年为6.1%。通过对16S rRNA基因进行测序，我们首次在FVG地区的蓖麻硬蜱中发现了瑞士立克次氏体，在两个地区的蜱中均发现了蒙氏立克次氏体。此外，我们在从高山地区获得的一只蜱中检测到了与柠檬立克次氏体序列高度同源的序列。
