Ex vivo bacterial clearance of S. aureus from pig skin wounds after treatment with CEN1 HC and CEN1 HC (Ser). Wounds infected with S. aureus (106 CFU) were treated with CEN1 HC, in concentrations of 0.1, 0.5 and 2 mg/mL, and sampling/bacterial counting was performed four hours after treatment. Results are presented as mean of relative bacterial survival (%) ± SEM compared to the non-treated control group (n = 10 for all groups except for the groups treated with 0.5 and 2 mg/mL of CEN1 HC (Ser), where n = 9). One outlier (p < 0.01, Grubbs’ test) was discarded from each of the groups treated with 0.5 and 2 mg/mL CEN1 HC (Ser). * = p < 0.05, ** = p < 0.01, *** = p < 0.001 comparing CEN1 HC to the control group, $ = p < 0.05, $$$ = p < 0.001 comparing CEN1 HC (Ser) to the control group.
