Minimal bactericidal concentration of liposomal formulations in comparison with their minimal inhibitory concentration. Modified minimal inhibitory concentration (MIC) assay (square symbols, left y-axis) was performed with S. epidermidis followed by determination of minimal bactericidal concentration (round symbols, right y-axis). Test lipids were a palmitic acid prepared in carrier-4 (PA4); b stearic acid prepared in carrier 4 (SA4); and c cholesteryl linoleate prepared in carrier-3 (CL3). RFU relative fluorescence units. Dotted line bacterial inoculum (CFU/mL). Shown are means of two experiments conducted in duplicates
