Viral yield reduction - post-adsorption stage. a compounds or b their mixtures present only after viral adsorption. Culture supernatants collected for virus titration (CCID50) after 24, 48 and 72 h of incubation. Nisin (N) concentrations in μg/mL, lysozyme (Lys) and lactoferrin (LF) concentrations in mg/mL; control: untreated cells. All data expressed as means ± SD (standard deviation) for n = 3 independent experiments. Asterisks refer to statistically significant differences between control and compound-treated virus at: *p<0.05, ** p<0.01, *** p<0.001
