Bats (order Chiroptera) are some of the most abundant mammals on earth and their species ecology strongly influences zoonotic potential. While substantial research has been conducted on bat-associated viruses, particularly on those that can cause disease in humans and/or livestock, globally, limited research has focused on endemic bats in the USA. The southwest region of the US is of particular interest because of its high diversity of bat species. We identified 39 single-stranded DNA virus genomes in the feces of Mexican free-tailed bats (Tadarida brasiliensis) sampled in the Rucker Canyon (Chiricahua Mountains) of southeast Arizona (USA). Twenty-eight of these belong to the virus families Circoviridae (n = 6), Genomoviridae (n = 17), and Microviridae (n = 5). Eleven viruses cluster with other unclassified cressdnaviruses. Most of the viruses identified represent new species. Further research on identification of novel bat-associated cressdnaviruses and microviruses is needed to provide greater insights regarding their co-evolution and ecology relative to bats.
蝙蝠（翼手目）是地球上数量最多的哺乳动物之一，它们的物种生态强烈影响着人畜共患的潜力。虽然已经对蝙蝠相关病毒进行了大量研究，特别是那些可能导致人类和/或牲畜患病的病毒，但全球范围内，对美国本土蝙蝠的研究有限。美国西南部地区因其蝙蝠物种的高度多样性而特别引人关注。我们从美国亚利桑那州东南部的 Rucker Canyon（奇里卡瓦山脉）采集的墨西哥游离尾蝠（Tadarida brasiliensis）的粪便中鉴定出了 39 种单链 DNA 病毒基因组。其中 28 种属于圆环病毒科（n=6）、基因组病毒科（n=17）和微病毒科（n=5）。11 种病毒与其他未分类的 cressdnaviruses 聚类。鉴定出的大多数病毒都是新的物种。需要进一步研究新的蝙蝠相关 cressdnaviruses 和微病毒，以更好地了解它们与蝙蝠的共同进化和生态。
