Effect of PEDV infection on IPEC-J2 cells. (a) IPEC-J2 cells were observed at 12, 24, 36 and 48 h after inoculation with strain CV777. Compared with the negative control, the infected cells showed obvious fusion and eventually peeled off the surface of the Petri dish. (b) Growth curve of PEDV in IPEC-J2 cells. (c) Expression of PEDV nsp16 in IPEC-J2 cells after infection with PEDV (bar: 60 µm) (d) Expression of PEDV N in IPEC-J2 cells after infection with PEDV (bar: 60 µm)
