What is the characterisic morphology of Sporothrix schenckii yeast form?

• A. Spherical budding yeast
• B. Filamentous hyphae
• C. Cigar-shaped yeast
• D. Pseudohyphae

Answer: (C)

Sporothrix schenckii is a dimorphic fungus. In tissue at body temperature it grows as yeast, and the characteristic yeast cells are slender and elongated—cigar-shaped—about a few micrometers long. This distinctive morphology stands out from other yeasts that appear as round budding cells (like Candida or Cryptococcus), and from the mold form that shows filamentous hyphae in the environment. Pseudohyphae are a yeasty, elongated chain form seen with Candida, not Sporothrix. So the cigar-shaped yeast is the hallmark of the yeast form in Sporothrix schenckii.
