Polarized e-bandage treatment reduces endpoint bacterial loads. The 48-h wound bed biofilms containing MRSA (A) or MRSA plus P. aeruginosa (PA; B) were treated for 48-h with either polarized (HOCl-producing) or non-polarized e-bandages, with or without systemic antibiotics (MRSA alone, vancomycin – VAN; MRSA plus P. aeruginosa – vancomycin plus amikacin - Abx) and compared with Tegaderm only controls, with and without antibiotics. Statistical analysis was performed using the Wilcoxon rank sum test with correction for false discovery rate. Individual data points with the means (bars) are shown. Solid black significance bars show differences between non-antibiotic-treated groups; dashed dark grey significance bars show differences between antibiotic-treated groups; light gray dashed and dotted significance bars show differences between antibiotic and non-antibiotic-treated groups with the same e-bandage treatment type. N ≥ 7. *P ≤ 0.05, **P ≤ 0.01.
