What is the main reservoir for Histoplasma capsulatum in nature?

Explanation:
Histoplasma capsulatum is a dimorphic fungus that thrives in soil enriched with nitrogen from bird or bat droppings. In the environment, it exists as mold and produces tiny spores (microconidia) that become airborne when the soil is disturbed. Humans inhale these spores, which can lead to histoplasmosis. This makes soil with bird or bat guano the main natural reservoir, not freshwater, human skin, or undersea environments. Common contexts include caves with bat guano, chicken coops, and other places with large bird or bat populations in endemic regions.
