Spectrum of antiviral activity of the peptides (TCID₅₀ assay). Peptides (50 μg/ml) and viruses were incubated at 37 °C for 1 h before they were added to the target cell monolayers. After incubation for 48–72 h, TCID₅₀ of the virus was recorded. The bars represent ± SE. Three separate assays were conducted (n = 3). The dashed line means 50% residual infectivity
