Ixodes persulcatus and Ixodes pavlovskyi ticks, two closely related species of the I. ricinus - I. persulcatus group, are widely distributed in the southern part of Western Siberia. Recently, the existence of natural hybrids of I. persulcatus and I. pavlovskyi ticks has been demonstrated. The aim of this study was to evaluate the abundance of I. persulcatus/pavlovskyi hybrids in several locations with different ratios of parental tick species and to investigate the prevalence and genetic variability of a wide range of infectious agents in these hybrids compared to the parental tick species. Natural hybrids of I. persulcatus and I. pavlovskyi ticks were identified in all examined locations in Altai and Novosibirsk, Western Siberia, Russia. The abundance of hybrids varied from 7% to 40% in different locations and was maximal in a location with similar proportions of I. persulcatus and I. pavlovskyi ticks. For the first time, it was shown that hybrids can be infected with the same agents as their parental tick species: tick-borne encephalitis and Kemerovo viruses, Borrelia afzelii, Borrelia bavariensis, Borrelia garinii, Borrelia miyamotoi, Rickettsia helvetica, Rickettsia raoultii, Rickettsia sibirica, “Candidatus Rickettsia tarasevichiae”, Anaplasma phagocytophilum, Ehrlichia muris, “Candidatus Neoehrlichia mikurensis”, and Babesia microti. The prevalence of most bacterial agents in hybrids was intermediate compared to their parental tick species. Most genetic variants of the identified agents have been previously found in the parental tick species. Wide distribution of I. persulcatus/pavlovskyi natural hybrids implies that I. persulcatus, I. pavlovskyi and their hybrids coexist in all I. persulcatus - I. pavlovskyi sympatric areas.

Isodes persulcatus和Ixodes pavlovskyi的壁虱是蓖麻的两个紧密相关的物种-Persulcatus组，广泛分布在西西伯利亚的南部。近日，自然杂交的存在I. persulcatus和一个pavlovskyi蜱已被证明。本研究的目的是评估的丰度I. persulcatus / pavlovskyi杂种与亲本蜱物种的不同比率的几个位置，并调查与亲蜱宽范围在这些杂种传染剂的患病率和遗传变异物种。的自然杂交种一个persulcatus和在俄罗斯西伯利亚的阿尔泰和新西伯利亚的所有检查地点都发现了帕夫洛夫斯基壁虱。在不同位置，杂种的丰度从7％到40％不等，并且在百分数I. persulcatus和I. pavlovskyi壁虱的比例最大的地方。这是第一次，它表明混合动力车可以感染相同的代理商作为他们的父母蜱物种：蜱传脑炎和克麦罗沃病毒，螺旋体afzelii，疏螺旋体bavariensis，疏螺旋体garinii，疏螺旋体miyamotoi，立克次体黑体，立克次体raoultii，立克次氏体山杏，“暂定立克次体tarasevichiae”无形体吞噬细胞，埃立克体缪里斯，‘暂定Neoehrlichia mikurensis’，和巴贝斯田鼠。与它们的亲代tick种相比，杂种中大多数细菌因子的患病率处于中等水平。先前已在亲代壁虱物种中发现了鉴定出的病原体的大多数遗传变异。I. persulcatus / pavlovskyi自然杂种的广泛分布意味着I. persulcatus，I。pavlovskyi及其杂种共存于所有I. persulcatus - I. pavlovskyi同居地区。
