A novel polyomavirus (PyV) was identified in the intestinal contents of Japanese eastern bent-wing bats (Miniopterus fuliginosus) via metagenomic analysis. We subsequently sequenced the full genome of the virus, which has been tentatively named Miniopterus fuliginosus polyomavirus (MfPyV). The nucleotide sequence identity of the genome with those of other bat PyVs was less than 80%. Phylogenetic analysis revealed that MfPyV belonged to the same cluster as PyVs detected in Miniopterus schreibersii. This study has identified the presence of a novel PyV in Japanese bats and provided genetic information about the virus.

通过宏基因组分析，在日本东部弯翅蝙蝠 ( Miniopterus fuliginosus ) 的肠道内容物中发现了一种新型多瘤病毒 (PyV)。我们随后对该病毒的全基因组进行了测序，暂时将其命名为Miniopterus fuliginosus polyomavirus (MfPyV)。该基因组的核苷酸序列与其他蝙蝠 PyVs 的核苷酸序列同一性低于 80%。系统发育分析表明，MfPyV 与在Miniopterus schreibersii中检测到的 PyV 属于同一簇。这项研究确定了日本蝙蝠中存在一种新型 PyV，并提供了有关该病毒的遗传信息。
