Which of the following is found in the yeast phase of Sporothrix schenckii on culture medium at 37 degrees C?

• A. Cigar-shaped yeast cells
• B. Yeast-like colonies
• C. Round yeast spores
• D. Filamentous structures

Answer: (A)

Sporothrix schenckii is a dimorphic fungus that can exist in two forms: as a filamentous mold at lower temperatures (around 25 degrees C) and as a yeast at warmer temperatures, specifically around 37 degrees C, which is significant for its pathogenicity in humans. When grown at 37 degrees C, Sporothrix schenckii converts to its yeast phase, which is characterized by the presence of cigar-shaped yeast cells. This particular morphology is a key diagnostic feature associated with this pathogen and is crucial for identifying it in clinical laboratory settings. Understanding the nature of these yeast cells is important for mycology and clinical microbiology since the presence of cigar-shaped cells in tissue or culture confirms the diagnosis of sporotrichosis, the disease caused by Sporothrix schenckii. The ability to recognize this distinct morphology helps differentiate it from other fungi and aids in the implementation of appropriate treatments.
