Candida albicans can be differentiated from other Candida species on cornmeal agar by its unique ability to form which of the following
## **Core Concept**
Candida albicans is a type of yeast that can be differentiated from other Candida species based on its unique morphological characteristics on specific agar media. Cornmeal agar is one such medium used for this purpose. The differentiation is primarily based on the formation of specialized structures.
## **Why the Correct Answer is Right**
The correct answer, , refers to the formation of chlamydoconidia. Chlamydoconidia are a type of asexual, resting spore formed by some fungi, including Candida albicans. These structures are characteristic of C. albicans when grown on cornmeal agar or other specific media. The formation of chlamydoconidia is a key identifying feature for C. albicans, helping to distinguish it from other Candida species.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because, although some Candida species may form structures like blastoconidia, this is not unique to C. albicans and does not specifically differentiate it on cornmeal agar.
- **Option B:** This option is incorrect as it does not specify a known structure associated with the differentiation of C. albicans on cornmeal agar.
- **Option D:** This option is incorrect because, similar to option B, it does not accurately represent a structure used for the identification of C. albicans.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that the ability to form chlamydoconidia on cornmeal agar at 25°C is a classic method for identifying Candida albicans. This characteristic is particularly useful in the microbiology lab for species identification. Remember, "C. albicans makes chlamydoconidia."
## **Correct Answer:** . Chlamydoconidia
