| Outline of Final Research Achievements |
Fungal and mite overgrowth in the living environment poses a risk of health hazards, such as allergies and infectious diseases, to the occupants. They are thought to increase or decrease as a result of indoor and outdoor temperature, relative humidity, house performance such as insulation, cleaning frequency by the residents, and other factors. Furthermore, they may also contribute to each other's growth. Therefore, we investigated the distribution of fungi and mite allergens in house dust collected from living environments. We also conducted co-culture experiments of fungi and mites in the laboratory to explore the relationship between fungal and mite growth, as well as the factors in the living environment that promote the growth of fungi and mites.
The results indicated a correlation between certain fungi and mite growth, as well as between factors associated with house performance and/or building materials and fungal and mite growth.

本研究の成果から、真菌とダニの増殖関連性および住宅に関連した因子と真菌やダニ増殖の関連性の一部を示すことができた。住環境の真菌・ダニそれぞれの増殖要因について言及した研究は多いが、住環境における両者の増殖の関連性については検討が進んでおらず、エビデンスはほとんど得られていない。真菌やダニは、日本人の居住空間に普遍的に分布する生物だが、様々な要因によって容易に増殖し、居住者の健康に大きな影響を与えることは多くの研究によって支持されている。住まいのダニと真菌の共増殖に関するエビデンスを得た意義は大きく、住環境衛生において有益な情報が得られ、居住者のＱＯＬの向上が期待できる。
