Influence of Culture Media on Biofilm Formation by Candida Species and Response of Sessile Cells to Antifungals and Oxidative Stress

Figure 4

Biofilms formed by Candida species as observed by SEM. Samples were observed with a LEICA F-420 SIGMA model and scanning electron microscope using a normal electrode SE detector at 10 kV under high vacuum conditions and at a working distance of 4 mm. (a) C. albicans in YPD/2%; (b) C. glabrata in YNB/0.2%, (c) C. krusei in YPD/2%, and (d) C. parapsilosis in YPD/2%. The scale bar is indicated for each microphotography. White arrows indicate yeast, hyphae, or pseudohyphae cells.
