The prevalence of mould genera and their association with the house dust mite Dermatophagoides pteronyssinus (Trt.) were investigated in the homes of 192 asthmatic patients and 125 healthy people in a Romanian town (Brasov) with a relatively high degree of humidity. The dominant moulds which developed in the culture media exposed on the bedroom floors were Cladosporium, Penicillium and Aspergillus. Living examples of D. pteronyssinus and their eggs were present mostly in the colonies of Cladosporium; in colonies of Penicillium, the mites were dead and disintegrated. It is concluded that allergy to D. pteronyssinus must not be connected with house dust as such but to the presence in the dust of certain mould spores.
