Introduction. Dimorphic fungi are organisms that have the ability to switch between two morphologies during their lifecycle: yeast and hyphae (Gauthier, 2015; Klein and Tebbets, 2007). Dimorphism can be induced by several stimuli, such as oxygen concentration, nutrient sources and enzymatic activity (Gauthier, 2015).
They share a common ancestor with animals in the eukaryotic supergroup Opisthokonta and have a deeper common ancestry with plants, yet several phenotypes, such as morphological, physiological, or nutritional traits, make them unique among all living organisms.
A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast. As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]
24 Ιαν 2018 · Dimorphic fungi can live in four different forms; mold, hyphal, filamentous or as a yeast. Many species of dimorphic fungi are pathogenic to humans and other organisms. In humans, temperature is the main regulator of the form the fungus takes.
7 Αυγ 2015 · Dimorphic switching requires the fungus to sense and respond to the host environment and is essential for pathogenicity. This review will focus on the role of dimorphism in fungi commonly called thermally dimorphic fungi, which switch to a yeast growth form during infection.
21 Νοε 2023 · Dimorphic fungi are defined as fungi that spend part of their life cycle as a yeast and part of their life cycle as a mold. What is dimorphism in fungi and what is its significance?
9 Μαρ 2023 · The morphology and life cycle of dimorphic fungi are complex and influenced by various factors, including temperature, carbon dioxide concentration, pH, nutrient availability, host factors, and genetic factors.
