Fig. 6From: Evaluation of antiviral activity of Bacillus licheniformis-fermented products against porcine epidemic diarrhea virusAntiviral activity of crude extract derived from Bacillus licheniformis (BLFP) against PEDV infection, as well as the IC50, was determined using the AlamarBlue™ assay. a PEDV-infected Vero cells treated with (left) and without (middle) 150 ppm BLFP crude extract. The right panel shows Vero cells without any treatment. Brown coloration indicates a positive PEDV S protein signal located in the cytoplasm of PEDV-infected cells. b Dose-dependent effect of BLFP crude extract against PEDV. The half-maximal inhibitory concentration (IC50) of BLFP crude extract against PEDV in Vero cells is 0.07 ± 0.45 ppm. Data are presented as the mean ± SD out of three test replicatesBack to article page
