|A.||Culture on Sabouraud agar|
Calcofluor white stain
Answer: C) Löwenstein–Jensen agar
Explanation:This is a typical presentation of a fungal keratitis. Löwenstein–Jensen agar is used to help identify mycobacteria. Sabouraud agar is used to help identify fungi. Calcofluor white binds to the cell walls of fungi and Acanthamoeba, enhancing their visibility under a fluorescent microscope. Giemsa stains are useful for identifying fungi, bacteria, and intracytoplasmic inclusions in chlamydial infections by light microscopy.
