Question

A female presented with curdy white discharge. Sample microscopy showed a budding yeast cell with pseudohyphae. Which medium is used to differentiate the species of the causative organism?

• A. Bird seed agar
• B. Chrome agar
• C. SDA
• D. PDA

Hint:

Chrome agar is useful for identifying and differentiating Candida species based on colony color changes.

Answer 1

The Correct Option is B

The medium used to differentiate the species of the causative organism in this case, which is likely to be Candida, is Chrome agar. This medium is designed to help identify different species of Candida based on their color change in the presence of specific chromogenic substrates. Other media like Bird seed agar, SDA (Sabouraud Dextrose Agar), and PDA (Potato Dextrose Agar) are also used for fungal growth, but Chrome agar is preferred for species differentiation.
