Effect of erythrosine- and LED-mediated photodynamic therapy on buccal candidiasis infection of immunosuppressed mice and Candida albicans adherence to buccal epithelial cells.

Objective: This study evaluated the effects of photodynamic therapy (PDT) on buccal candidiasis in mice and on the adherence of yeast to buccal epithelial cells (BECs) in vitro.

Study Design: A total of 56 immunosuppressed mice with buccal candidiasis were subjected to PDT, consisting of treatment with erythrosine (400 μmol/L) followed by exposure to a green LED (14.34 J cm(-2)).

Susceptibility of Candida albicans and Candida dubliniensis to erythrosine- and LED-mediated photodynamic therapy.

The effect of erythrosine- and LED-mediated photodynamic therapy (PDT) on planktonic cultures and biofilms of Candida albicans and Candida dubliniensis was evaluated. Planktonic cultures of standardized suspensions (10(6)cells/mL) of C. albicans and C.
