Effect of SPS on the antimicrobial activity of various antimicrobial agents. Mixtures of 10 μL of SAAP-148 (1% wt/v), pexiganan (1% wt/v), chlorhexidine (0.5% v/v in 70% alcohol) or PBS and 400 μL of PBS, 0.05, 0.1, 0.5% or 1% (wt/v; final concentrations) SPS in PBS were prepared. Ninety μL of LUH14616 with a final concentration of 105 CFU/mL were added to these mixtures to determine the antimicrobial activity after 30 min incubation at 37 °C and 5% CO2. The means and standard deviations (SD) of three independent experiments performed in duplicate are shown. Results are expressed as the number of surviving bacteria in log10 CFU/mL. * indicates significant difference as compared to the samples without SPS (*p < 0.05)
