(A) The copy numbers of porcine epidemic diarrhea virus (PEDV) in infected IPEC-J2 cells at different time points. IPEC-J2 cells were infected with the PEDV CV777 strain at 0.1 MOI. After 0.5 h, 1 h, 2 h, and 3 h of incubation, viral copies were quantified by qPCR. (B) Lactobacillus salivarius inhibits the infection of IPEC-J2 cells by PEDV. IPEC-J2 cells were treated with different concentrations of L. salivarius (1, 10, and 100 MOI) for 2 h before PEDV infection. Then, IPEC-J2 cells were infected with PEDV CV777 at 0.1 MOI for 1 or 2 h. The copy numbers of PEDV in each group were detected by qPCR. The differences between the groups were analyzed using the Kruskal–Wallis test. Significant differences are marked with asterisks. ^*: p < 0.05, ^**: p < 0.01.
