| Outline of Final Research Achievements |
Candida, an endemic fungus, is one of the causes of aspiration pneumonia in the elderly, and many cases recur even after treatment with antifungal agents. In order to develop a new fundamental treatment method, we investigated the application of antimicrobial photodynamic therapy (aPDT), which has recently been attracting attention in the treatment of periodontal disease.Irradiation of the dye, which is used as a dental plaque stain, showed bactericidal effects due to the production of reactive oxygen species (ROS) and oxidative damage to proteins. This study suggests the possibility of a new highly effective bactericidal treatment for Candida.

| Academic Significance and Societal Importance of the Research Achievements |
これまで,口腔内の真菌に対する治療は口腔ケアと抗真菌薬の治療のみであった。今回の検討によりカンジダ菌に対する新規の殺菌効果の高い治療法の可能性が示唆された。このことから、新たな真菌治療に対するセルフケアアプローチの可能性が見出された。しかしながら本研究は基礎検討であることから今後臨床応用に向けたさらなる検討も必要である。
