  abstract     = {We investigated the cellular mechanisms responsible for the occurrence of miconazole-tolerant persisters in Candida albicans biofilms. Miconazole induced about 30\% killing of sessile C. albicans cells at 75 mu M. The fraction of miconazole-tolerant persisters, i.e., cells that can survive high doses of miconazole (0.6 to 2.4 mM), in these biofilms was 1 to 2\%. Since miconazole induces reactive oxygen species (ROS) in sessile C. albicans cells, we focused on a role for superoxide dismutases (Sods) in persistence and found the expression of Sod-encoding genes in sessile C. albicans cells induced by miconazole compared to the expression levels in untreated sessile C. albicans cells. Moreover, addition of the superoxide dismutase inhibitor N,N'-diethyldithiocarbamate (DDC) to C. albicans biofilms resulted in an 18-fold reduction of the miconazole-tolerant persister fraction and in increased endogenous ROS levels in these cells. Treatment of biofilms of C. albicans clinical isolates with DDC resulted in an 18-fold to more than 200-fold reduction of their miconazole-tolerant persister fraction. To further confirm the important role for Sods in C. albicans biofilm persistence, we used a Delta sod4 Delta sod5 mutant lacking Sods 4 and 5. Biofilms of the Delta sod4 Delta sod5 mutant contained at least 3-fold less of the miconazole-tolerant persisters and had increased ROS levels compared to biofilms of the isogenic wild type (WT). In conclusion, the occurrence of miconazole-tolerant persisters in C. albicans biofilms is linked to the ROS-detoxifying activity of Sods. Moreover, Sod inhibitors can be used to potentiate the activity of miconazole against C. albicans biofilms.},
