Earlier, we demonstrated the co-circulation of genetically distinct non-rodent-borne hantaviruses, including Boginia virus (BOGV) in the Eurasian water shrew (), Seewis virus (SWSV) in the Eurasian common shrew () and Nova virus (NVAV) in the European mole (), in central Poland. To further investigate the phylogeny of hantaviruses harbored by soricid and talpid reservoir hosts, we analyzed RNAlater-preserved lung tissues from 320 shrews and 26 moles, both captured during 1990-2017 across Poland, and 10 European moles from Ukraine for hantavirus RNA through RT-PCR and DNA sequencing. SWSV and Altai virus (ALTV) were detected in and in Boginia and the Białowieża Forest, respectively, and NVAV was detected in in Huta Dłutowska, Poland, and in Lviv, Ukraine. Phylogenetic analyses using maximum-likelihood and Bayesian methods showed geography-specific lineages of SWSV in Poland and elsewhere in Eurasia and of NVAV in Poland and Ukraine. The ATLV strain in from the Białowieża Forest on the Polish-Belarusian border was distantly related to the ATLV strain previously reported in from Chmiel in southeastern Poland. Overall, the gene phylogenies found support long-standing host-specific adaptation.
早些时候,我们在波兰中部发现了基因不同的非啮齿动物传播汉坦病毒的共同循环,包括波戈尼亚病毒(BOGV)在欧亚水鼩()、塞维斯病毒(SWSV)在欧亚普通鼩()和诺瓦病毒(NVAV)在欧洲鼹鼠()中传播。为了进一步研究沙鼠和鼩鼱等储存宿主携带的汉坦病毒的系统发育,我们通过 RT-PCR 和 DNA 测序分析了 1990 年至 2017 年间在波兰各地捕获的 320 只鼩鼱和 26 只鼩鼱以及 10 只来自乌克兰的欧洲鼩鼱的 RNAlater 保存的肺组织中的汉坦病毒 RNA。在博戈尼亚和比亚沃韦扎森林的 和 中检测到了 SWSV 和阿尔泰山病毒(ALTV),在波兰的胡塔杜托夫斯卡(Huta Dłutowska)和乌克兰的利沃夫(Lviv)检测到了 NVAV。最大似然和贝叶斯方法的系统发育分析显示,波兰和欧亚其他地区的 SWSV 以及波兰和乌克兰的 NVAV 具有特定地理区域的谱系。在波兰与白俄罗斯边境的比亚沃韦扎森林的 中发现的 ATLV 株与之前在波兰东南部赫姆利(Chmiel)报道的 ATLV 株关系较远。总的来说,发现的基因系统发育支持长期以来的宿主特异性适应。
