Figure 2: Virucidal activity on PRRSV of C. dactylon study reagent at a concentration of 0.78 mg/mL. C. dactylon study reagent was incubated with PRRSV for one hour at room temperature before inoculated onto a monolayer of MARC-145 cells. After three days in vitro, virus titer was quantified by IPMA. C. dactylon significantly inactivated PRRSV compared to the control group, while virus alone with DMEM remained infective on MARC-145 cells. Asterisks indicate statistical significance (   value ≤ 0.05).
