(A) Growth of C. albicans strains SC5314 and ATCC10231 under different stress conditions (addition of itraconazole, ethanol, 5-FOA). Growth on SD plates served as a control. Both strains were tested at 30°C and at 37°C. (B) Invasion of SC5314 and ATCC10231 into carbon-depleted agar surface. After growth of the colonies, plates were washed with water removing the non-invasive cells and photographed. (C) Influence of different pH-values on the growth of SC5314 and ATCC10231 at iron- (150 μM BPS) and phosphate-limiting (0.15 mM Pi) conditions and under cation stress (1 M NaCl). Growth on YPD at pH 5 and pH 8, respectively, served as a control. Numbers under the single colonies represent the number of cells used for inoculation of each spot (also related to A and C).
