family comprises single-stranded, positive-sense RNA viruses distributed into forty-seven genera. Picornaviruses have a broad host range and geographic distribution in all continents. In this study, we applied a high-throughput sequencing approach to examine the presence of picornaviruses in penguins from King George Island, Antarctica. We discovered and characterized a novel picornavirus from cloacal swab samples of gentoo penguins (), which we tentatively named Pingu virus. Also, using RT-PCR we detected this virus in 12.9 per cent of cloacal swabs derived from , but not in samples from adélie penguins () or chinstrap penguins (). Attempts to isolate the virus in a chicken cell line and in embryonated chicken eggs were unsuccessful. Our results expand the viral diversity, host range, and geographical distribution of the .
该病毒科包含单链正义RNA病毒，分为47个属。小RNA病毒具有广泛的宿主范围，在各大洲均有地理分布。在本研究中，我们应用高通量测序方法检测了南极乔治王岛企鹅体内小RNA病毒的存在情况。我们从巴布亚企鹅的泄殖腔拭子样本中发现并鉴定了一种新型小RNA病毒，我们暂时将其命名为平古病毒。此外，我们通过逆转录聚合酶链反应在12.9%的巴布亚企鹅泄殖腔拭子中检测到了这种病毒，但在阿德利企鹅或帽带企鹅的样本中未检测到。尝试在鸡细胞系和鸡胚中分离该病毒均未成功。我们的结果扩展了小RNA病毒的病毒多样性、宿主范围和地理分布。
