Systemic mycoses are fungal infections that can impact internal organs and spread throughout the body. Many of these infections are zoonotic, meaning they can be transmitted between animals and humans. Common examples include histoplasmosis, blastomycosis, cryptococcosis, and coccidioidomycosis. These infections are typically contracted by inhaling fungal spores from the environment, especially from soil contaminated with animal droppings. While some individuals may remain asymptomatic or experience mild symptoms, others can develop severe illness affecting the lungs, skin, bones, and central nervous system (CNS). Early diagnosis and prompt treatment with antifungal medications are crucial for effectively managing systemic mycotic zoonoses.
