Susceptibility of porcine IPI-2I intestinal epithelial cells to infection with swine enteric coronaviruses

•IPI-2I cells are susceptible to TGEV, PDCoV, and PEAV.•IPI-2I cells can be infected with PEDV, but with low efficiency.•A homogeneous cell line IPI-FX is obtained from IPI-2I cells by sub-cloning.•IPI-FX cells are highly susceptible to PEDV, TGEV, PDCoV, and PEAV.
