Origin: Found world wide. One of the most common fungal spores on air samples. Is often found in indoor air, damp walls, carpets, etc.. Certain species are food contaminants, others are found in woody rotting vegetation, soil, textiles, and cultivated and wild grasses.
Health effects: Some species are saprophytic and are not important in human or plant disease. Other species can cause systemic infections where initial inhalation leads to lung infections, which disseminates to other organs.The brain is sometimes involved. It is becoming more prevalent in patients with AIDS, organ transplants, leukaemia, autoimmune disease and Cushings Syndrome. Certain species can cause deep skin infections and can invade the central nervous system. They can cause sinusitis, respiratory diseases, and subcutaneous mycoses. May also cause keratomycosis and allergies.
Lesions can occur anywhere in the body if a puncture occurs with contaminated vegetation.
The species in air samples are impossible to differentiate microscopically. This makes it impossible to separate the non-pathogenic species from the potentially pathogenic ones. Cladosporium, however, can occur in such high numbers, that it probably should always be considered as a possible source of infection when fungi are suspected.
