In the Neotropical region, the white-winged vampire bat (Diaemus youngi) is the rarest of the three species of vampire bats. This bat species feeds preferentially on bird blood, and there is limited information on the viruses infecting D. youngi. Hence, this study aimed to expand the knowledge about the viral diversity associated with D. youngi by sampling and pooling the lungs, liver, kidneys, heart, and intestines of all animals using high-throughput sequencing (HTS) on the Illumina MiSeq platform. A total of three complete and 10 nearly complete circular virus genomes were closely related to gemykrogvirus (Genomoviridae family), smacovirus (Smacoviridae family), and torque teno viruses (TTVs) (Anelloviridae family). In addition, three sequences of bat paramyxovirus were detected and found to be closely related to viruses reported in Pomona roundleaf bats and rodents. The present study provides a snapshot of the viral diversity associated with white-winged vampire bats and provides a baseline for comparison to viruses detected in future outbreaks.
在新热带地区，白翼吸血蝠（Diaemus youngi）是三种吸血蝙蝠中最稀有的一种。这种蝙蝠物种优先以鸟类血液为食，关于感染 D. youngi 的病毒的信息有限。因此，本研究旨在通过使用 Illumina MiSeq 平台进行高通量测序（HTS）对所有动物的肺、肝、肾、心脏和肠道进行采样和汇集，扩大与 D. youngi 相关的病毒多样性知识。总共获得了三个完整的和十个几乎完整的圆形病毒基因组，它们与 gemykrogvirus（Genomoviridae 科）、smacovirus（Smacoviridae 科）和 torque teno viruses（TTVs）（Anelloviridae 科）密切相关。此外，还检测到三种蝙蝠副粘病毒序列，与在波莫纳圆叶蝙蝠和啮齿动物中报告的病毒密切相关。本研究提供了与白翼吸血蝠相关的病毒多样性的快照，并为未来爆发中检测到的病毒提供了基线比较。
