Outline of Final Research Achievements

Candida albicans is the most common species of Candida spp. And It is one of the main pathogens which cause catheter related blood stream infection by making biofilm on medical devises. PslG is one of the hydrolase which P. aeruginosa possesses. In this study, we evaluated and found the effect of hydrolase PslG on Candida biofilm in vitro and in vivo. We found that it binds to the mannan of C. albicans and interfere the Als-3 mediated aggregation of hyphae during biofilm formation.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、C. albicansによるカテーテル関連感染症の予防に有用なカテーテルコーティング剤の開発に有用である可能性がある。このような技術の報告は限られており、もし、今後臨床応用できれば、カンジダ関連血流感染症でもっとも多いC. albicansによるカテーテル関連感染症を減らすことができる可能性がある。それにより、カンジダ血症による死亡を抑制できる可能性があり、社会的意義は大きい。
