Abstract

BACKGROUND

Wild birds are an important but to some extent under-studied reservoir for emerging pathogens. We used unbiased sequencing methods for virus discovery in shorebird samples from the Delaware Bay, USA; an important feeding ground for thousands of migratory birds.

FINDINGS

Analysis of shorebird fecal samples indicated the presence of a novel astrovirus and coronavirus. A sanderling sample yielded sequences with distant homology to avian nephritis virus 1, an astrovirus associated with acute nephritis in poultry. A ruddy turnstone sample yielded sequences with homology to deltacoronaviruses.

CONCLUSIONS

Our findings highlight shorebirds as a virus reservoir and the need to closely monitor wild bird populations for the emergence of novel virus variants.

摘要

背景

野生鸟类是新出现病原体的重要宿主，但在一定程度上研究不足。我们采用无偏差测序方法在美国特拉华湾的滨鸟样本中发现病毒；特拉华湾是数千只候鸟的重要觅食地。

研究结果

对滨鸟粪便样本的分析表明存在一种新型星状病毒和冠状病毒。一只三趾滨鹬样本产生了与禽肾炎病毒1具有远缘同源性的序列，禽肾炎病毒1是一种与家禽急性肾炎相关的星状病毒。一只赤翻石样本产生了与δ冠状病毒具有同源性的序列。

结论

我们的研究结果突出了滨鸟作为病毒宿主的地位，以及密切监测野生鸟类种群以发现新型病毒变体出现的必要性。
