Key result
Experimental infection of 1-day-old goslings with the newly isolated GoAstV-GD2101 strain reproduced clinical symptoms of gout and resulted in a 36.3% mortality rate.
Why the study?
Goose astroviruses cause fatal gout and reduce waterfowl industry performance, and epidemiologic studies are necessary for vaccine development because no effective vaccines exist.
Population
94 gout samples from goose farms in Guangdong Province, South China
Design
Isolation, genomic sequencing, and pathogenicity study

Establishes GoAstV-2 causality in gosling gout model; leaves open field epidemiology and intervention strategies.
Absolute Event Rate: 36.3% vs 0%
The study confirms that the newly emerging GoAstV-2 is the causative pathogen for fatal gout in goslings in South China.
Xu et al. (2023) studied Goose gout (n=116). GoAstV-GD2101 isolate vs. PBS was evaluated on Mortality. Experimental infection of 1-day-old goslings with the newly isolated GoAstV-GD2101 strain reproduced clinical symptoms of gout and resulted in a 36.3% mortality rate.
