The aim of the investigation was to evaluate different methods to sample microbial cell wallagents (MCWA) indoors and to relate the results to clinical markers of inflammation amongpersons (n = 27), living in houses with suspected mould problems. Airborne particles weresampled for 8 h or by agitating floor dust. Sedimented particles were collected from floor dust.Analysis was done for endotoxin and (1?3)--D-glucan. Endotoxin was found only in a few ofthe agitated floor dust samples. There was a relation between airborne endotoxin levels and thesecretion of certain Th1-type cytokines from stimulated blood mononuclear cells and between(1?3)--D-glucan in floor dust and the total amount of IgE in serum. Boarder values were definedfor endotoxin at 0.2 ng/m3 and for (1?3)--D-glucan at 25 ng/mg floor dust.
