The number of ileum SWC3a⁺/MHC-II⁺DCs increases after oral inactivated PEDV. SWC3a⁺/MHC-II⁺ DCs were showed by Immunofluorescence staining. The number of SWC3a⁺/MHC-II⁺ DCs in per view was counted and statistical analysis was performed. Significant differences between the treated groups and the control groups are identified as. Scale bar = 100 μm, n = 10 *p < 0.05
