[Mycoses caused by fungal spores in indoor air].

Fungal spores in indoor air may cause mycoses and allergies in man. The following different types of exposure are interesting from the epidemiological view-point: (a) the occupational exposure (work done with fungi-contaminated material), (b) the accidental exposure (formation and growing of fungi by constructive defects), and (c) the inconspicuous constant exposure (as part of lifestyle, e.g. by plants or small pets). It is stressed that the only way to characterize the indoor air quality with regard to its content of fungal spores is by uncontestable mycological diagnostics.
