Fungal spores collection and analysis
Fungal spores collection and analysis was performed as previously described (Takahashi, 1997).
Air fungal spores were collected by a surface air sampler (AINEX BIO-SAS, International Pbi S.p.a., Italy) using dichloran 18% glycerol agar (DG-18) as cultural medium for 100 s, with an airflow rate of 1 l/s, at an air inlet height of 1.5m in the living room.
All fungal concentrations were expressed as colony forming units per cubic meter
of air (cfu/m3).
