Immune-related gene expression in the kidneys and spleens of goslings infected with goose nephritic astrovirus.

ABSTRACT: Goose nephritic astrovirus (GNAstV) was first isolated in 2018, causing great economic losses to the goose industry. However, little is known about host immune response to GNAstV infection. In this study, forty 2-day-old goslings were randomly divided into 2 groups: infection and negative control groups. Each gosling in the infection group was challenged with 0.5 mL GNAstV-JSHA intramuscularly, whereas the gosling in the negative control group was inoculated with the same amount of PBS. Histopathological changes and virus location in the spleen and kidney were examined, and the expression of immune-related genes was determined by qPCR at 7 and 14 d after infection. Our results showed that GNAstV infection induced degeneration and necrosis of splenic lymphocytes and renal epithelial cells,
