Tick-borne rickettsiae are an important topic in the field of emerging infectious diseases. In the study, we screened a total of 1473 field-collected Ixodes ricinus ticks (1294 nymphs, 99 males, and 80 females) for the presence of human pathogenic rickettsiae (Rickettsia helvetica, R. monacensis, 'Candidatus Neoehrlichia mikurensis', and Anaplasma phagocytophilum) in natural and urban ecosystems using molecular techniques. The minimum infection rate (MIR) for Rickettsia spp. was found to be 2.9% in an urban park and 3.4% in a natural forest ecosystem; for 'Candidatus Neoehrlichia mikurensis', we observed MIRs of 0.4% in the city park and 4.4% in the natural habitat, while for A. phagocytophilum the MIR was 9.4% and 1.9%, respectively. Our study provides the first data on the occurrence of human pathogenic rickettsiae in questing I. ricinus ticks in the Czech Republic.
蜱传立克次氏体是新发传染病领域的一个重要课题。在本研究中，我们使用分子技术，在自然和城市生态系统中，对总共1473只野外采集的蓖麻硬蜱（1294只若虫、99只雄蜱和80只雌蜱）进行筛查，以检测是否存在人类致病性立克次氏体（瑞士立克次氏体、蒙纳氏立克次氏体、“嗜吞噬细胞无形体”和嗜吞噬细胞无形体）。在城市公园中，立克次氏体属的最低感染率（MIR）为2.9%，在天然森林生态系统中为3.4%；对于“米库新埃立克次氏体”，我们观察到城市公园中的MIR为0.4%，自然栖息地中的MIR为4.4%，而嗜吞噬细胞无形体的MIR分别为9.4%和1.9%。我们的研究提供了捷克共和国野外蓖麻硬蜱中人类致病性立克次氏体出现情况的首批数据。
