Abstract:In the present work viable fungal spore counts and flora of indoor air were compared in various residences. Total viable spore counts were lowest in the urban/suburban residences and highest in the rural residences. Moisture problems in the urban environment did not increase total viable spore count, but affected composition of fungal flora. In the rural environment, spore counts were much higher in the old houses than in the new ones. Penicillium was the most prevalent fungus in the air of all the residences studied. Airborne Aspergillus, Cladosporium spores and yeast cells were more common in the damp residences and the old rural houses than in the other residences.
