Resumo: This study investigated the adhesion to human epithelial cells and polystyrene surface of viable yeasts recovered from Candida biofilms treated with silver nanoparticles (SN). Biofilm resuspended Candida cells were added to HeLa cells or to empty wells of microtiter plates and the adhesion was verified using crystal violet staining. The adhesion of Candida cells was significantly reduced, mainly when biofilms were pretreated with 54 μg/mL SN. These new findings allow to conclude that SN may induce changes in viable yeasts, which can decrease the dissemination of Candida infections, mainly in susceptible patients.
