Unexpected link between iron and drug resistance of Candida spp.: iron depletion enhances membrane fluidity and drug diffusion, leading to drug-susceptible cells.

Abstract excerpt

Inthis study, we show that iron depletion in Candida albicans with bathophenanthrolene disulfonic acid and ferrozine as chelators enhanced its sensitivity to several drugs, including the most common antifungal, fluconazole (FLC). Several other species of Candida also displayed increased sensitivity to FLC because of iron restriction. Iron uptake mutations, namely, Deltaftr1 and Deltaftr2, as well as the copper...
