Key result
RT-PCR detects a novel goose astrovirus distinct from known avastroviruses in diseased domestic geese.
Why the study?
The diversity and role of astroviruses circulating in domestic waterfowls, specifically geese, were not fully understood.
Identified a novel group of avian Avastrovirus in domestic geese in China, expanding the understanding of domestic waterfowls as reservoirs for diverse astroviruses.
Hypothesis-generating for waterfowl astrovirus diversity; prospective studies needed to clarify reservoir and zoonotic roles.
Using an ORF1b-based astrovirus-specfic reverse transcription (RT)-PCR assay, a novel astrovirus-like was detected from domestic geese in China. Pairwise comparisons and phylogenetic analyzes suggested that a novel group of goose astrovirus, different with previously known astroviruses in the genus Avastrovirus, was found circulating in geese. This study has expanded our understanding about the role of domestic waterfowls as reservoirs for diverse astroviruses.

Wan et al. (2018) studied Astrovirus infection. Novel goose astrovirus infection was evaluated on Phylogenetic analysis and sequence identity of the RdRp gene. A novel group of goose astrovirus, distinct from previously known avastroviruses, was detected in diseased domestic geese in China.
