The Sonoran Desert tortoise Gopherus morafkai is adapted to the desert, and plays an important ecological role in this environment. There is limited information on the viral diversity associated with tortoises (family Testudinidae), and to date no DNA virus has been identified associated with these animals. This study aimed to assess the diversity of DNA viruses associated with the Sonoran Desert tortoise by sampling their fecal matter. A viral metagenomics approach was used to identify the DNA viruses in fecal samples from wild Sonoran Desert tortoises in Arizona, USA. In total, 156 novel single-stranded DNA viruses were identified from 40 fecal samples. Those belonged to two known viral families, the Genomoviridae (n = 27) and Microviridae (n = 119). In addition, 10 genomes were recovered that belong to the unclassified group of circular-replication associated protein encoding single-stranded (CRESS) DNA virus and five circular molecules encoding viral-like proteins.

沙漠龟粪便样品中的病毒发现：新型环状单链DNA病毒。

索诺兰沙漠乌龟Gopherus morafkai适应沙漠，并在这种环境中起着重要的生态作用。关于乌龟（睾丸科）的病毒多样性的信息有限，迄今为止，尚未发现与这些动物有关的DNA病毒。这项研究旨在通过采样粪便来评估与索诺兰沙漠龟有关的DNA病毒的多样性。病毒宏基因组学方法用于鉴定来自美国亚利桑那州索诺兰沙漠野生乌龟粪便样品中的DNA病毒。总共从40个粪便样品中鉴定出156种新的单链DNA病毒。它们属于两个已知的病毒家族，即Genomoviridae（n = 27）和Microviridae（n = 119）。此外，
