The antiviral effect of copper chloride on different FCV strains. The F81 cells were infected with different FCV strains at 100 TCID50 and treated with 80 μM copper chloride. After incubation for 28 h at 37 °C in 5% CO2, the virus titre (a) and the relative RNA levels (b) of FCV were detected; * p < 0.1234 and ** p < 0.0021
