A novel goose astrovirus (SDXT strain) was identified as the causative agent of an acute outbreak of visceral gout with a 30% mortality rate in Cherry Valley ducklings.
A novel goose astrovirus (SDXT strain) was identified as the cause of a highly acute disease with 30% mortality in ducklings, indicating potential cross-host infection.
A highly acute disease broke out in ducklings in Shandong Province in March 2019. The disease was characterized as visceral gout, with a mortality rate of 30%. The causative agent, which has given rise to similar symptoms in goslings, has been confirmed to be a novel goose astrovirus. The novel goose astrovirus, which was designated as the SDXT strain, was identified from a diseased duck farm using duck embryo primary cells in an experimental infection test. Genomic sequence analysis, as well as phylogenetic analysis of the viral proteins, revealed that the SDXT strain was closely related to a novel goose astrovirus of the Avastrovirus three species. These results indicate that the novel goose astrovirus may cross-host infect ducklings. Further studies are needed to define its host range and transmission route.
Chen et al. (Sat,) conducted a other in Novel goose astrovirus infection. Novel goose astrovirus (SDXT strain) was evaluated on Mortality rate. A novel goose astrovirus (SDXT strain) was identified as the causative agent of an acute outbreak of visceral gout with a 30% mortality rate in Cherry Valley ducklings.
