We have sequenced the genomic 3′-end, including the structural gene, of human astrovirus (HAstV) serotype 7 and morphologically related viruses infecting pig (PAstV), sheep (OAstV) and turkey (TAstV-1). These sequences were compared with corresponding astrovirus sequences available in the nucleic acid databases, including sequences of the seven other HAstV serotypes, two other avian astroviruses (TAstV-2 and avian nephritis virus) and astrovirus from cat (FAstV). A 35 nt stem–loop motif near the 3′-end of the genome, previously described as being highly conserved, was present in all of the astroviruses except TAstV-2. In the N-terminal half of the capsid precursor protein, there were several short conserved peptide motifs. Otherwise the capsid proteins of astroviruses infecting different hosts were highly divergent. Calculation of genetic distances revealed that the distance between FAstV and HAstV is comparable to the largest distances between different HAstV serotypes. Higher similarities between the HAstV, FAstV and PAstV capsid sequences suggest interspecies transmissions involving humans, cats and pigs relatively recently in the evolutionary history of astroviruses.

Abstract Astroviruses are considered the cause of gastroenteritis in humans and animals. Studies in recent years show avian astroviruses are also associated with duckling hepatitis, gosling gout, and chicken nephritis. In this study, a GAstV strain, designated as JS2019/China, was detected in dead goslings from a commercial goose farm in Jiangsu province of China. Viral strain was proliferated in goose embryos and sequence analysis showed the isolated strain had a classical structure arrangement and a series of conserved regions compared with other GAstVs. Sequence comparison and phylogenetic analysis of whole genome and ORF2 revealed that JS2019/China belongs to the GAstV group-1, which consists of most of the GAstV strains. Amino acid analysis indicated that some mutants might have an impact on viral protease capacity, such as V505I and K736E of ORF1a and T107I, F342S, and S606P of ORF2. Taken together, a novel GAstV strain was isolated and genomic analysis and protein polymorphism analysis indicated that some amino acid mutants might affect the viral virulence.
