Bacterial viability after antimicrobial photodynamic therapy with curcumin on multiresistant .

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. In this study the APDT response on growth, viability, formation of reactive oxygen species and adhesion of methicillin-sensitive strains of , strains of methicillin-resistant  and American-type culture collection (ATCC) of were evaluated , after incubation with curcumin for 20 min, and irradiated with LED.
