Staphylococcus aureus are multiresistant pathogens that causes superficial and systemic infections. Antimicrobial photodynamic therapy (APDT) is an alternative in the treatment of diseases caused by these bacteria. Aim: In this study the APDT response on growth, viability, formation of reactive oxygen species and adhesion of methicillin-sensitive strains of Staphylococcus aureus, strains of methicillin-resistant S. aureusand American-type culture collection (ATCC) of S. aureus were evaluated in vitro, after incubation with curcumin for 20min, and irradiated with LED. Materials & methods: Bacterial growth was assessed by the number of colony-forming units, viability and adhesion were evaluated by confocal microscopy and ROS quantification was performed by fluorimetry. Results: Was observed increase in the production of ROS in APDT groups, besides a decrease in the 4 log growth and loss of the bacterial adhesion. Conclusion: APDT with Curcumin may be an interesting therapeutic alternative, due to its in vitro response, in the control multiresistant clinical S. aureus strains.
