How are pseudohyphae formed
Web1 de jan. de 2001 · Pseudohyphae formation is induced by growth on a variety of solid media (Spider, milk-Tween, etc.) while true hyphae are formed in liquid media containing serum or in Lee’s medium at pH 6.7. The role of the MAP kinase pathway in the transition from yeast to pseudohypha in C. albicans has been well established.
