Summary As part of aetiological studies, we tested 28 samples collected from domestic geese showing enteritis and sporadic death. A novel group of avastroviruses was found in six samples. One isolate was completely sequenced, which comprised 7,148 nucleotides. Pairwise comparisons and phylogenetic analysis demonstrated that the goose astrovirus is highly divergent from all previously described avastroviruses. Our data support the view that domestic geese can be infected by astroviruses with different genetic backgrounds, and have raised a concern about the role of domestic geese as reservoirs for diverse astroviruses.
