Final answer:
Bat and bird droppings can cause fungus disease in the lungs, such as histoplasmosis and cryptococcosis.
Step-by-step explanation:
Bat and bird droppings can lead to various diseases, including fungal diseases in the lungs. When droppings from these animals are inhaled, they can cause respiratory infections such as histoplasmosis, which is caused by the fungus Histoplasma capsulatum.
This fungus grows in soil that has been contaminated with bird or bat feces. When spores from this fungus are inhaled, they can multiply within the lungs, occasionally leading to chronic lung disease. Another example is cryptococcosis, which is a fungal pneumonia caused by the encapsulated yeast Cryptococcus neoformans, commonly found in bird droppings.
