The recent detection of both Nova virus (NVAV) and Bruges virus (BRGV) in European moles () in Belgium and Germany prompted a search for related hantaviruses in the Iberian mole (). RNAlater-preserved lung tissue from 106 Iberian moles, collected during January 2011 to June 2014 in Asturias, Spain, were analyzed for hantavirus RNA by nested/hemi-nested RT-PCR. Pairwise alignment and comparison of partial L-segment sequences, detected in 11 Iberian moles from four parishes, indicated the circulation of genetically distinct hantaviruses. Phylogenetic analyses, using maximum-likelihood and Bayesian methods, demonstrated three distinct hantaviruses in Iberian moles: NVAV, BRGV, and a new hantavirus, designated Asturias virus (ASTV). Of the cDNA from seven infected moles processed for next generation sequencing using Illumina HiSeq1500, one produced viable contigs, spanning the S, M and L segments of ASTV. The original view that each hantavirus species is harbored by a single small-mammal host species is now known to be invalid. Host-switching or cross-species transmission events, as well as reassortment, have shaped the complex evolutionary history and phylogeography of hantaviruses such that some hantavirus species are hosted by multiple reservoir species, and conversely, some host species harbor more than one hantavirus species.
近期在比利时和德国的欧洲鼹鼠()中检测到新星病毒(NVAV)和布鲁日病毒(BRGV),促使人们在伊比利亚鼹鼠()中寻找相关汉坦病毒。通过巢式/半巢式 RT-PCR 对 2011 年 1 月至 2014 年 6 月期间在西班牙阿斯图里亚斯采集的 106 只伊比利亚鼹鼠的 RNAlater 保存的肺组织进行汉坦病毒 RNA 分析。对在来自四个教区的 11 只伊比利亚鼹鼠中检测到的部分 L 片段序列进行了成对比对和比较,表明存在遗传上不同的汉坦病毒。使用最大似然法和贝叶斯法进行的系统发育分析表明,伊比利亚鼹鼠中有三种不同的汉坦病毒:NVAV、BRGV 和一种新的汉坦病毒,命名为阿斯图里亚斯病毒(ASTV)。在使用 Illumina HiSeq1500 对来自 7 只感染鼹鼠的 cDNA 进行下一代测序的过程中,一个产生了可行的连续体,跨越了 ASTV 的 S、M 和 L 片段。每个汉坦病毒物种都由单个小型哺乳动物宿主物种携带的原始观点现在已被证明是无效的。宿主转换或跨物种传播事件以及重组事件塑造了汉坦病毒的复杂进化历史和系统地理学,使得一些汉坦病毒物种由多个储存物种携带,反之亦然,一些宿主物种携带不止一种汉坦病毒。
