Distribution of Dermatophagoides mite (Acari : Pyroglyphidae) antigens in homes of allergic patients in Japan.
Dust samples collected in 61 homes of patients with mite allergies and 11 homes of non-allergic people as controls were examined for antigen levels of Dermatophagoides farinae Hughes and Dermatophagoides pteronyssinus (Trouessart) to reveal the current distribution of allergenic mites in homes in Japan.
Patient homes had higher antigen levels than control homes in comforters and pillows but not in futons, carpets, tatamis and wooden floors.
Samples with antigen levels of = 10 mug m-2 were more frequent in and around summer (approximately April-October) than other seasons of the year in most materials and the differences between patient and control homes in comforters and pillows observed in yearly totals was also observed during this period.
Wooden structures showed higher antigen levels than concrete structures in comforters, futons, pillows, carpets and tatamis in patient homes.
Mite contamination in patient homes in relation to environmental factors was discussed.
