Genome Features and In Vitro Activity against Influenza A and SARS-CoV-2 Viruses of Six Probiotic Strains

Figure 3

The number (in %) of viable MDCK cells after virus infection at a dose of 100 TCID/50 and during incubation with different concentrations of bacteria. Along the abscissa axis is the logarithm of bacteria concentration, and along the ordinate axis is the % of viable cells. A positive control (uninfected cells were cultured without probiotic bacteria) is 100% viable cells. The results are from three independent experiments. .
