Dimorphic fungi

Dimorphic fungi are a unique group of fungi that can exist in two different forms: as molds (hyphal, filamentous structures) in the environment, and as yeasts (single-celled organisms) when they infect humans or animals. This ability to change forms depends on temperature and other conditions. They are responsible for certain infections, especially in immunocompromised individuals, including diseases like histoplasmosis and blastomycosis. Understanding their dual nature is important for diagnosis and treatment, as different forms are visible under different laboratory conditions, and their pathogenic forms often require specific medical interventions.
