C. albicans is the most common Candida species, which causesopportunistic infections in immunocompromised hosts. It forms the part of the normal flora of the mucous membrane of the gastrointestinal, genitourinary, and respiratory tract.
· C. albicans is ovoid or spherical yeast with a single bud.
· It forms the part of the normal flora of the mucous mem-brane of the gastrointestinal, genitourinary, and respira-tory tract. It produces pseudohyphae in the cultures and in tissues. Pseudohyphae are elongated yeast that may resemble hyphae morphologically, but are really not true hyphae. Candida grows readily on Sabouraud’s dextrose agar and onbacteriological culture media. C. albicans produces creamy white, smooth colonies with a yeasty odor (Color Photo 64).
· It can be differentiated from other Candida species by carbohydrate fermentation reaction and by characteristic growth properties.
· Only C. albicans produces chlamydospores on cornmeal agar culture at 25°C.
