Which two diseases are commonly transmitted from contaminated soil?

Histoplasmosis and Cryptococcus are both diseases associated with contaminated soil.

Histoplasmosis is caused by the fungus Histoplasma capsulatum, which grows in soil that contains large amounts of bat or bird droppings. When the soil is disturbed, spores can become airborne and lead to respiratory infections upon inhalation.

Cryptococcus is primarily transmitted through the inhalation of spores found in soil, particularly in areas contaminated with bird feces, as the fungus Cryptococcus neoformans often thrives in those environments. It can lead to severe neurological diseases, particularly in immunocompromised individuals.

The other pairings mentioned do not primarily originate from contaminated soil. For example, Aspergillosis is associated with mold that can be found in various environments but is not soil-specific like the fungi causing histoplasmosis and cryptococcosis. Cocciodimycosis (coccidioidomycosis) is linked to soil as well, but it is not paired correctly with a soil-associated disease in the correct answer.

Hence, the pair of Histoplasmosis and Cryptococcus is proper and applicable in the context of diseases transmitted from contaminated soil.
