The spectrum of ixodid ticks that bite humans in Western Siberia has significantly changed over the past two decades. In this study, we determined tick species attacking people in the vicinity of Novosibirsk and the range of bacterial agents they were infected with. This study included 301 ticks taken from people and 46% were , followed by (19.6%), / interspecies hybrids (19.6%), (12.8%), and single and /. Human DNA was determined in ticks, first demonstrating that all spp., including hybrids, can effectively feed on humans. The DNA of spp., spp., and Anaplasmataceae bacteria was detected in different tick species. prevailed in species, being found in 8.8% of ticks, whereas and were found in single ticks. was revealed in 3.7% of ticks. " Rickettsia tarasevichiae" and were identified mainly in and (44.8% and 26.3%, respectively), while was found only in 2.2% . The prevalence of , and did not exceed 2%. The obtained results indicate a high risk for humans to be infected with agents of Lyme borreliosis, primarily .
在过去二十年里,西西伯利亚叮咬人类的硬蜱种类谱发生了显著变化。在本研究中,我们确定了新西伯利亚附近叮咬人类的蜱种以及它们感染的细菌病原体范围。本研究纳入了从人身上采集的301只蜱,其中 占46%,其次是 (19.6%)、 /种间杂交种(19.6%)、 (12.8%),以及单只的 和 /。在蜱中检测到了人类DNA,首次证明所有 属物种,包括杂交种,都能有效地以人类为食。在不同蜱种中检测到了 属、 属和无形体科细菌的DNA。 在 种中占优势,在8.8%的蜱中被发现,而 和 仅在单只蜱中被发现。在3.7%的蜱中检测到了 。“塔拉谢维奇立克次体”和 在 属和 属中主要被鉴定出来(分别为44.8%和26.3%),而 在仅2.2%的 属中被发现。 、 和 的感染率不超过2%。所获结果表明人类感染莱姆病病原体,主要是 的风险很高。
