To investigate the effect of up-regulation of CSGalNAcT2 on IBDV replication, DF1 cells were infected with IBDV at an MOI of 0.01, after transfection with pCSGalNAcT2, and the viral titre in the supernatant was determined by TCID50 at 48 h post-infection. This evidence concerns the gene CSGALNACT2 and infection.
