The Correct answer is B

  • Candida albicans is a dimorphic fungus, i.e. it can take two forms.
  • Most of the time it exists as oval, single yeast cells, which reproduce by budding. Most yeasts do not produce mycelia (a mass of branching, threadlike hyphal filaments), but Candida has a trick up its sleeve.
  • Normal room temperatures favour the yeast form of the organism, but under physiological conditions (body temperature, pH, and the presence of serum) it may develop into a hyphal form.
  • Pseudohyphae, composed of chains of cells, are also common.
  • Chlamydospores may be formed on the pseudomycelium.
Cryptococcus neoformans- Only yeast phase but unusual in that the cells are encapsulated as demonstrated by an India Ink stain.
