is a genus of viruses in the family , order with a segmented circular RNA genome. They typically infect birds and mammals and are primarily transmitted by ectoparasites such as ticks. Four of nine genogroups can infect humans, with Crimean-Congo hemorrhagic fever virus infections displaying case fatality rates up to 40%. Here, we discover and describe a novel as Cencurut virus (CENV). CENV was detected in 34 of 37 Asian house shrews () sampled in Singapore and in a nymphal tick collected from an infected shrew. Pairwise comparison of CENV S, M, and L segments had 95.0 to 100% nucleotide and 97.5 to 100% amino acid homology within CENV genomes, suggesting a diverse viral population. Phylogenetic analysis of the individual gene segments showed that CENV is related to Erve, Lamgora, Lamusara, and Thiafora viruses, with only 49.0 to 58.2% nucleotide and 41.7 to 61.1% amino acid homology, which has previously been detected in other shrew species from France, Gabon, and Senegal respectively. The high detection frequency suggests that CENV is endemic among populations in Singapore. The discovery of CENV, from a virus family with known zoonotic potential, underlines the importance of surveillance of synanthropic small mammals that are widely distributed across Southeast Asia.
是 科 目 中的一个病毒属,具有分段环状RNA基因组。它们通常感染鸟类和哺乳动物,主要通过蜱等体外寄生虫传播。九个 基因群中的四个可以感染人类,克里米亚-刚果出血热病毒感染的病死率高达40%。在这里,我们发现并描述了一种新型 病毒,命名为森库鲁特病毒(CENV)。在新加坡采集的37只亚洲家鼩中的34只以及从一只受感染的鼩鼱身上采集的一只若蜱中检测到了CENV。CENV的S、M和L片段的成对比较显示,在CENV基因组内,核苷酸同源性为95.0%至100%,氨基酸同源性为97.5%至100%,这表明存在多样化的病毒群体。对各个基因片段的系统发育分析表明,CENV与埃尔夫病毒、拉姆戈拉病毒、拉穆萨拉病毒和蒂亚福拉病毒有关,核苷酸同源性仅为49.0%至58.2%,氨基酸同源性为41.7%至61.1%,此前分别在法国、加蓬和塞内加尔的其他鼩鼱物种中检测到。高检测频率表明CENV在新加坡的 种群中是地方性流行的。从一个具有已知人畜共患病潜力的病毒家族中发现CENV,凸显了监测广泛分布于东南亚的共生小型哺乳动物的重要性。
