Figure 7. Synergistic activity of ebselen with topical antimicrobials.
The Bliss Model for Synergy confirms a synergistic effect, between ebselen and topical antimicrobials (mupirocin, fusidic acid, retapamulin and daptomycin) against various resistant strains of S. aureus. Degree of synergy was quantified after 12 h of treatment with ebselen (0.0312 μg/ml) in combination with sub-inhibitory concentrations of topical antimicrobials. (Circle) daptomycin + ebselen, (Square) retapamulin + ebselen, (Triangle) fusidic acid + ebselen and (Inverted triangle) mupirocin + ebselen.
