摘要：Aspergilli constitute a serious risk to the health of the inhabitants of infested rooms. Mycological analysis conducted in buildings infected with moulds in the area of the Lubuskie province (Poland) demonstrated the presence of 9 species of Aspergillus moulds: A. carbonarius A. clavatus, A. flavus, A. fumigatus, A. niger, A. ochraceus, A. terreus, A ustus and A. versicolor. The highest frequency (4 - frequently) was observed in the case of A. versicolor, while frequency 3 (fairly frequently) was characteristic of such species as A. flavus and A. niger. A. ustus was encountered with frequency 2 (individually), while frequency 1 (sporadically) referred to four species: A. carbonarius, A. clavatus, A. fumigatus and A. terreus. Because Aspergillus versicolor occurs with the highest frequency in buildings, and as a consequence of this, synthesizes toxic and carcinogenic sterigmatocystin (ST), it constitutes the greatest risk to the inhabitants of the infested premises. All species of Aspergillus present on building partitions are able to synthesise mycotoxins, are pathogens and may cause allergies.
