Cladosporium

Habitat and Health Implications
Widely found as plant pathogens and saprobes. It is the most frequently
found fungus in outdoor air. It is often found indoors, usually in lesser
numbers than outdoors. It usually occurs at low concentrations in damp or
humid areas, but may be found in high concentrations in water-damaged
building materials. This fungus is often encountered in dirty refrigerators.
Frequently isolated as a contaminant in foods. It is commonly found on the
surface of fiberglass duct liners in the interior of supply ducts. It is also
found on dead plants, woody plants, food, straw, soil, paint, and textiles.
Cladosporium often discolors interior paint, paper, or textiles stored under
humid conditions. The ability to sporulate heavily, ease of dispersal, and
large spores makes this fungus the most important fungal airway allergen. It
is a common and important allergen causing hay fever, asthma, and HP. A
few species of this genus cause disease in humans; one species can cause
chronic subcutaneous infection. Some species produce Cladosporin and
Emodin.
