Abstract: This experiment was conducted to explore the molecular pathogenic mechanism of the interaction between novel goose parvovirus (NGPV) and host cells. In this study, transcriptome sequencing was performed on the liver, thymus and ileum of ducklings 14 days after infection with NGPV SD strain. The results showed that there were 78 up-regulated genes and 31 down-regulated genes in the ileum of the infected group; 111 up-regulated genes and 78 down-regulated genes in the thymus of the infected group; 128 up-regulated genes and 313 down-regulated genes in the liver of the infected group. The differentially expressed genes in thymus, ileum and liver of ducklings infected with NGPV are involved in many immune related biological processes, such as immune response process and lymphocyte mediated immunity. The differential genes are enriched in multiple signaling pathways such as Toll-like receptor signaling pathway, JAK-STAT signaling pathway, NF-κB signaling pathway, PI3K-Akt signaling. It is suggested that NGPV infection activates the body's immune response and the relevant antiviral signal pathways of host cells. This study provides new clues for the study of the pathogenic mechanism of NGPV.
