RESUMO
The qualitative and quantitative mycological composition of indoor areas of three private residencies and an academic dormitory in Wroclaw, Poland was investigated. Seasonal fungal samples were obtained using a MAS-100 air sampler. The samples were cultured on three different media: Sabouraud Agar (SAB), Dichloran Glycerol Selective Medium (DG18) and Malt Extract Agar (MEA). The number of colony forming unit (CFU) values ranged from 10 CFU/m3 to 490 CFU/m3 depending on the culture medium, season, and sampling site. The identification of the cultured fungi was performed using macro- and microscopic observations and diagnostic keys. Eleven fungal genera were identified. The most common fungi were members of genera Cladosporium, Penicillium, Aspergillus, Alternaria, and Fusarium; the least common fungi were members of genera Geotrichum and Paecilomyces. Seasonal variations in the concentration of fungi were observed with the highest concentration of fungi in the spring and the lowest concentration of fungi in the winter. There were no statistically significant correlations between fungal concentrations and the temperature or the relative humidity of the sample sites.
