Abstract excerpt

Goose astrovirus genotype 2 (GAstV-2), a member of the Avastrovirus (AAstV) genus, is an important emerging pathogen closely associated with gosling gout that has caused enormous economic losses to the goose industry since it was first reported in 2015 in China. However, public GAstV-2 sequencing data remain scarce (with only 278 records to date), and its genetic evolution, pathogenic features, and cross-species...
