A Viability of BHK-21, Vero, and PK-15 cells pretreated with the indicated concentrations of Vi for 18 h, 16 h, and 20 h, respectively. Western blot and TCID₅₀ were used to examine the inhibition activity of Vi against SVA (B and C), EMCV (D and E), PEDV F and G and PRV (H and I). Error bars represent the mean ± SD. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001; ns: not significant.
