Viruses, Vol. 14, Pages 1759: Goose Astrovirus in China: A Comprehensive Review
Sun Goose astroviruses (GoAstVs) are small non-enveloped viruses with a genome consisting of a single-stranded positive-sense RNA molecule. A novel GoAstV was identified in Shandong in 2016 and quickly spread to other provinces in China, causing gout in goslings, with a mortality rate of approximately 50%. GoAstV can also cause gout in chickens and ducks, indicating its ability to cross the species barrier. GoAstV has only been reported in China, where it has caused serious losses to the goose-breeding industry. However, in view of its cross-species transmission ability and pathogenicity in chickens and ducks, GoAstV s...

Molecular characterization of chicken astrovirus from high embryonic mortality based on the capsid protein (ORF2) gene, in Brazil
The objective of this study was to use molecular methods to characterize the CAstV found in one breeding and three different incubation companies that reported increased embryonic mortality and the appearance of birds with white chick syndrome (WCS). RT-qPCR with SyBR green chemistry were used to determine the presence of the virus in the feces of breeders, organs of newborn chickens, and unhatched embryos. By sequencing the ORF2 that codes for the viral capsid, the strains responsible for these clinical signs were characterized using strains previously reported in Brazil, North America, Europe, and Asia. The percentage of...

Detection and molecular phylogenetic analysis of chicken astrovirus in Saga prefecture, Japan
AbstractWe detected three chicken astrovirus strains in 4-day-old broiler chickens with high mortality and visceral gout and one strain from 150-day-old hens without clinical symptoms in Saga prefecture, Japan. Phylogenetic analysis based on ORF2 amino acid sequences revealed that the strains from the visceral gout cases belonged to subgroup Bi, and the strain from hens without clinical symptoms belonged to subgroup Aiii. Our study showed that CAstV had infiltrated into Saga prefecture, Japan. This is the first report of CAstV in Japan. (Source: Archives of Virology)
