Oxidative stress and cell death in C. albicans. A. Effect of PMS on ROS generation in C. albicans cells determined by DCFH-DA staining. Cells were grown on YNBA with or without (control) 1 mM PMS, and with 10 mM H2O2 at 30°C. Fungal cells were harvested after 18 hours growth, washed and incubated with DCFH-DA for 30 minutes. Green fluorescence was evaluated by flow cytometry. B. C. albicans CAT1/CAT1 (WT CU2) or cat1/cat1 were grown on YNBA medium alone (control) and with PMS for 72 hours. Fungal survival determined by MB staining (n=3). Data are representative of at least two independent experiments ***P<0.01.
