- Fungi that exist in a mold form at lower temperatures in the environment, and a yeast form at higher temperatures in the host body
- Cryptococcus does exhibit dimorphism, though it is predominately yeast and its dimorphism is not likely related to disease
| Organism | Distribution | Diseases | Treatment |
|---|---|---|---|
| Blastomyces species | eastern US and Canada, with some reported in Africa | pulmonary infection, verrucous skin lesions, osteomyelitis, CNS infection | itraconazole (with amphotericin B induction if severe) |
| Coccidioides species | southwestern US and parts of South and Central America | pulmonary infection, verrucous skin lesions, osteomyelitis, CNS infection | fluconazole (with amphotericin B and flucytosine induction if severe) |
| Histoplasma capsulatum | worldwide, including eastern North America, Central and South America, sub-Saharan Africa, and parts of Southeast Asia | pulmonary infection, CNS infection | itraconazole (with amphotericin B induction if severe) |
| Paracoccidioides brasiliensis | South America | pulmonary infection | itraconazole (with amphotericin B induction if severe) |
| Sporothrix schenckii | essentially worldwide | nodular lymphangitis | itraconazole |
| Talaromyces marneffei | Southeast Asia | disseminated (common in advanced HIV), pulmonary infection, abdominal abscess, skin lesions, osteomyelitis | amphotericin B induction followed by itraconazole |
Distribution
- Endemic dimorphic fungi are widely distributed1
