Enumerate four dimorphic fungi
Q122 marksShort Notes
Answer
Four dimorphic fungi (mould at 25°C, converting to a tissue-invasive yeast/spherule form at 37°C):
- Histoplasma capsulatum — causes histoplasmosis; small intracellular yeast in macrophages at 37°C.
- Blastomyces dermatitidis — causes blastomycosis; broad-based budding yeast at 37°C.
- Coccidioides immitis — causes coccidioidomycosis; forms a spherule (not a yeast) at 37°C.
- Sporothrix schenckii — causes sporotrichosis; cigar-shaped budding yeast at 37°C.
(Other valid examples: Paracoccidioides brasiliensis; Talaromyces (Penicillium) marneffei.)
