Aspergillus mold is a very common type of fungus found virtually all over the world. Allergic aspergillosis is a condition that occurs when people inhale the microscopic spores of aspergillus, causing an immune response in the body that can include a high fever, asthma attacks, and coughing up blood and mucus.
Cladosporium mold is commonly found, in dying and dead plants, in the soil and on food. It thrives in a damp, dark, nonporous environment such as window frames and the inside of refrigerators. It will also multiply in houses with poor ventilation and in straw roofs built in low damp areas.
