Cytopathic effect inhibition by nisin+lactoferrin, lysozyme+lactoferrin and nisin+lysozyme mixtures after 5 days of incubation. The 50% endpoint virus titres (CCID₅₀) were calculated using the Reed and Muench method. Nisin concentrations in μg/mL, lysozyme and lactoferrin concentrations in mg/mL; control: untreated virus. All data expressed as means ± SD (standard deviation) for n = 3 independent experiments. Asterisks refer to statistically significant differences between control and treatments at: *p<0.05
