: the condition or property of being dimorphic or dimorphous: as a (1) : the existence of two different forms (as of color or size) of a species especially in the same population (2) : the existence of an organ in two different forms b: crystallization of a chemical compound in two different forms.
The signature feature of systemic dimorphic fungi â a family of six primary fungal pathogens of humans â is a temperature-induced phase transition. These fungi grow as a mold in soil at ambient temperature and convert to yeast after infectious spores are inhaled into the lungs of a mammalian host. Seminal work 20 years ago established that a temperature-induced phase transition from mold to yeast is required for virulence.
