The bar-headed goose is a typical high-altitude bird that primarily inhabits alpine lakes and wetlands in Central Asia, with a remarkable ability to adapt to high elevations. Previous studies have shown that they can be infected with parasites such as Cryptosporidium spp. At present, there were few reports on its infection with the virus.
In this study, we utilized viral metagenomics to conduct a detailed analysis of the viral components in the fecal samples of bar-headed geese () from the Tibet region of China.
Multiple novel viruses were identified including four novel astroviruses, four novel caliciviruses, ten novel circoviruses, and nineteen novel parvoviruses. Among them, four astroviruses shared the highest amino acid sequence identities of 63.45-99.47% with different avastrovirus strains. Four caliciviruses and ten circoviruses were identified as unclassified caliciviruses and unclassified circoviruses, separately. Nineteen parvoviruses clustering into four groups maybe four different novel species of the genus .
These newly discovered viruses have potential implications for the health of avian species, particularly bar-headed geese. This study not only helps us understand the health status of bar-headed geese, but also offers crucial genomic information for future disease prevention and treatment strategies.
斑头雁是一种典型的高原鸟类，主要栖息于中亚的高山湖泊和湿地，具有卓越的高海拔适应能力。先前的研究表明，它们可能感染隐孢子虫属等寄生虫。目前，关于其感染病毒的报道较少。
在本研究中，我们利用病毒宏基因组学对来自中国西藏地区的斑头雁粪便样本中的病毒成分进行了详细分析。
鉴定出多种新型病毒，包括四种新型星状病毒、四种新型杯状病毒、十种新型圆环病毒和十九种新型细小病毒。其中，四种星状病毒与不同禽星状病毒株的氨基酸序列同一性最高，为63.45%至99.47%。四种杯状病毒和十种圆环病毒分别被鉴定为未分类的杯状病毒和未分类的圆环病毒。十九种细小病毒聚为四组，可能是该属的四个不同新种。
这些新发现的病毒对鸟类健康，尤其是斑头雁的健康具有潜在影响。本研究不仅有助于我们了解斑头雁的健康状况，还为未来的疾病预防和治疗策略提供了关键的基因组信息。
