Growth curves of PRV in PK-15 cells in the presence or absence of Res. PK-15 cells were infected with PRV at an MOI of 0.01 and test Res (65.72 μM) solution for 1 h at 37 °C. PRV proliferated in the PK-15 cells in the presence or absence of Res within 48 h. The total DNA was extracted at the indicated time points, and copies of PRV were detected via real-time FQ-PCR. Values are means ± SD (n = 3).
