Assessment of virus-induced cell cytotoxicity. BHK-21 cells were infected at an MOI of 0.2 in the absence or presence of different concentrations of FF72 for 24 h or 72h. At the end of this period, cell viability was assessed using MTT assay. Percentage of cell viability was calculated based on conditions in which cells were not treated. Statistical significance was calculated using a nonparametric Student t test, in which # represents p values lower than 0.01 compared to vehicle-treated condition and * represents p values lower than 0.05 compared to CHIKV condition treated with vehicle.
