Candida albicans can be differentiated from other Candida species on cornmeal agar by its unique ability to form which of the following
Correct Answer: Chlamydospores
Description: Although multiple Candida species may cause disease in humans, C.albicans is the most frequent species identified. Chlamydospores (chlamydoconidia) are round, thick-walled spores formed directly from the differentiation of hyphae in which there is a concentration of protoplasm and nutrient material. They may be intercalary (within the hyphae) or terminal (end of hyphae). Germ tubes appear as hyphal-like extensions of yeast cells, usually without a constriction at the point of origin from the cell. Approximately 75 percent of the yeasts recovered from clinical specimens are C. albicans, and the germ-tube test can usually provide identification within 3 hours. The morphologic features of yeasts on cornmeal agar containing Tween 80 allow for the differentiation of C. albicans from five other Candida species. Ref:- Baveja textbook of Microbiology
