在多个物种的鼩、鼹鼠和蝙蝠中发现了基因上不同的汉坦病毒（汉坦病毒科），揭示了涉及跨物种传播的复杂进化历史。Seewis病毒（SWSV）广泛分布于欧亚普通鼩（Sorex araneus）、苔原鼩（Sorex tundrensis）和西伯利亚大齿鼩（Sorex daphaenodon）等多种鼩 鼱科昆虫的寄主范围内。此外，SWSV的遗传变异，以前被称为Artybash病毒（ARTV）和Amga病毒，已在Laxmann的鼩（Sorex caecutiens）中检测到。在这里，我们描述的地理分布和传播的SWSV和阿尔泰病毒（ALTV）在亚洲俄罗斯。全基因组序列分析表明，ALTV是汉坦病毒的一个新种，与SWSV有较远的亲缘关系。此外，勒拿河病毒（LENV）似乎是一种独特的汉坦病毒，在东西伯利亚和俄罗斯远东地区的拉克斯曼氏鼩和扁颅鼩（Sorex roboratus）中存在。另一种与ALTV相关的病毒，与来自美国的里普利营病毒更密切相关，已在俄罗斯远东地区的欧亚最小鼩（Sorex minutissimus）中发现。两种高度不同的病毒，ALTV和SWSV在西西伯利亚的普通鼩 鼱中共同传播，而LENV和SWSV的ARTV变体在东西伯利亚和俄罗斯远东的Laxmann 鼩 鼱中共同传播。ALTV和ALTV相关病毒似乎属于Mobatvirus属，而SWSV是Orthohantavirus属的成员。这些研究结果表明，ALTV和ALTV相关的汉坦病毒可能已经出现了古老的跨物种传播，随后在欧亚大陆的Sorex 鼩的多样化。
The discovery of genetically distinct hantaviruses (family Hantaviridae) in multiple species of shrews, moles and bats has revealed a complex evolutionary history involving cross-species transmission. Seewis virus (SWSV) is widely distributed throughout the geographic ranges of its soricid hosts, including the Eurasian common shrew (Sorex araneus), tundra shrew (Sorex tundrensis) and Siberian large-toothed shrew (Sorex daphaenodon), suggesting host sharing. In addition, genetic variants of SWSV, previously named Artybash virus (ARTV) and Amga virus, have been detected in the Laxmann’s shrew (Sorex caecutiens). Here, we describe the geographic distribution and phylogeny of SWSV and Altai virus (ALTV) in Asian Russia. The complete genomic sequence analysis showed that ALTV, also harbored by the Eurasian common shrew, is a new hantavirus species, distantly related to SWSV. Moreover, Lena River virus (LENV) appears to be a distinct hantavirus species, harbored by Laxmann’s shrews and flat-skulled shrews (Sorex roboratus) in Eastern Siberia and far-eastern Russia. Another ALTV-related virus, which is more closely related to Camp Ripley virus from the United States, has been identified in the Eurasian least shrew (Sorex minutissimus) from far-eastern Russia. Two highly divergent viruses, ALTV and SWSV co-circulate among common shrews in Western Siberia, while LENV and the ARTV variant of SWSV co-circulate among Laxmann’s shrews in Eastern Siberia and far-eastern Russia. ALTV and ALTV-related viruses appear to belong to the Mobatvirus genus, while SWSV is a member of the Orthohantavirus genus. These findings suggest that ALTV and ALTV-related hantaviruses might have emerged from ancient cross-species transmission with subsequent diversification within Sorex shrews in Eurasia.
