doi: 10.3390/ph17010034

Figure Lengend Snippet: The photodynamic action of curcumin against bacteria.

Article Snippet: 4 , Bacterial viability after antimicrobial photodynamic therapy with curcumin on multi-resistant Staphylococcus aureus , Methicillin-resistant S. aureus strains and American-type culture collection (ATCC) of Staphylococcus aureus are evaluated in vitro, after incubation with curcumin for 20 min, and irradiated with LED light at 450 nm. , Colony-forming units, confocal microscopy images, and flow cytometry. , PDT with curcumin may be an interesting therapeutic alternative, because of its in vitro response, for the control of multi-resistant clinical S. aureus strains. , [ ] .
