FIG. 3.
Response to protoporphyrin IX (PPIX)-mediated photodynamic inactivation (PDI) of Staphylococcus aureus revealing various resistance mechanisms. Each box plot represents the spread of bacterial response across different clinical isolates. RF, rifamycines; FA, fusidic acid; TCs, tetracyclines; AGs, aminoglycosides; TMP-SMX, trimethoprim/sulfamethoxazole; MLSB, macrolides, lincosamides, streptogramins B; KAN, kanamycin; TOB, tobramycin; GEN; gentamycin. The error bars represent minimum and maximum value of log10 unit reduction in viable counts.
