Biological characteristics of porcine epidemic diarrhea virus strains after 10, 64, or 120 passages. a Cytopathic effects of the three strains 12 hpi at an MOI of 0.01. b Immunofluorescence detection results for the P10, P64, and P120 strains in Vero cells infected at an MOI of 0.01 at 12 hpi. c Growth kinetics of the P10, P64, and P120 strains in Vero cells at an MOI of 0.01. Cell lysates were sampled at the designated time points and titrated using the titration for 50% tissue culture infectious dose infectivity assay. The asterisk means significant difference (***P < 0.001, **P < 0.01, and *P < 0.05). P10, PEDV after 10 passages; P64, PEDV after 64 passages; and P120, PEDV after 120 passages; MOI, multiplicity of infection; hpi, hours post infection
