Hemolytic effect of oshem, oshem1 and oshem 2 and alpha-hemolysin compared with alpha-hemolysin of Staphylococcus aureus . (a) The hemolytic effect on the hRBC at 0.3 μmol of oshem, oshem-1 and oshem-2 and α-hemolysin (these results expressed as hemolysis/% were compared to hemolytic toxin isolated from the α-hemolysin from Staphylococcus aureus). Each point represents the mean ± SD of n = 12 experiments, with *p < 0.05. (b) The comparative effect of different proteins at the dose of 1 μM. (c) Macrophage cell viability expressed as cell viability percentage; data are presented as mean ± SEM (n = 12, p ≤ 0.05).
