Bactericidal activity against different human pathogenic strains of VRV-PL-VIIIa pre-incubated with or without p-Bromophenacyl bromide. VRV-PL-VIIIa (12 μg/mL) was pre-incubated with or without a different concentration of p-Bromophenacyl bromide (6 μM) at 37 °C for 15 min and bactericidal activity was estimated in agar diffusion assay. The diameter of the clear zone was measured and plotted after subtracting the diameter of the well (5 mm). Results are expressed as mean ± SD for three independent assays, each performed in triplicate
