Background: The aim of the study was to analyse mycological state of buildings in Lodz and investigate associations between filamentous fungi contaminated flats and inhabitants health. Material and methods: 20 flats contaminated by moulds and 49 occupants were examined. Not-contaminated flats and their inhabitants were also examined. Air samples were collected in houses and outdoors. Moulds ability to producing mycotoxins was measured. SPT to common and fungal allergens as well as evaluation of total and serum specific IgE to moulds were performed. Results: 95% of investigated flats were excessively contaminated by moulds. High level of moulds contamination was found in the air of flats (average number of moulds - 4x 103 cfu/1m3) and in the diving walls (average - 4,7x 107 cfu/100m2). Species isolated from investigated rooms were: Penicillium (92%), Cladosporium (69%), Aspergillus (38%)and Alternaria (38%). The most frequent symptoms reported were rhinitis 29 (59,2%), conjunctivitis 29 (59,2%), chronic cough 24 (49%), dyspnea 15 (30,6%). 5 (10,2%) patients from moulds contaminated flats had positive SPT to moulds I or II and 8 (16,3%) with particular moulds. 3 persons (6,1%) had serum specific IgE to moulds. Conclusions: A numbers of fungal species are present in indoor air. A lot of symptoms are reported by occupants whereas the incidence of athopy is similar to that found in general population.
