Which medium supports morphological studies of Candida and produces chlamydospores in nutritionally deficient conditions?

• A. Czapek's Agar
• B. SABHI Agar
• C. Corn Meal Agar
• D. Mycosel Agar

Answer: (C)

Chlamydospore formation in Candida is best studied on a nutrient‑limited medium that nudges the organism into its developmental structures. Corn meal agar provides the low-nutrient environment and surface cues that promote the formation of chlamydospores—thick-walled resting spores that appear in association with hyphae. This makes it ideal for observing the distinctive Candida morphology used for identification, including these chlamydospores. Other media serve different purposes: Czapek’s agar is tailored for filamentous molds and doesn’t encourage Candida to form chlamydospores; Sabouraud dextrose agar supports general fungal growth but isn’t specialized for inducing those morphological features; Mycosel agar is selective to suppress contaminants, not to reveal Candida’s chlamydospore formation.
