4 Systemic Mycoses
- dimorphic fungi (mold in soil, yeast in tissue) except coccidiodomycosis
- Mold= cold; Heat=yeast
- all can cause PNEUMONIA and DISSEMINATE
- SYSTEMIC MYCOSES mimics TB (granulomas)
Tx: fluconazole or ketoconazole
1. Histoplasmosis- causes pneumonia
- Mississippi and Ohio R. Valleys
- bird or bat droppings
- intracellular (tiny yeast inside macrophages)
*** "Histo"="histiocyte" tissue macrophage
2. Blastomycosis= Big, Broad, Budding
3. Coccidiomycosis- California
- pneumonia and meningitis
- SPHERULE filled w/ endospores
- valley fever
