The effects of Q7R on PEDV-induced CPE. Culture medium 6-well tissue culture plates were removed and the cells were washed with PBS. Then, 0.09 ml of diluted virus suspension and 0.01 ml of medium supplemented with typsin-EDTA containing Q7R of 10 μg/ml were added. After incubation at 37°C in 5% CO₂ for 2 days, the morphology of cells was investigated under microscope and a photograph taken. (A) Non-infected cells; (B) PEDV-infected cells with Q7R; (C) non-infected cells with Q7R; (D) PEDV-infected cells without Q7R; (E) PEDV-infected cells with ribavirin; (F) non-infected cells with ribavirin.
