Research Abstract

抗生物質全盛の現代においても、感染症は依然として人類の脅威である。薬物耐性菌克服のための新たな方法論として、微生物を殺すのではなく、それらの定着を阻止することで感染を防御するという報告者らの独創的発想は実用化されると極めて有用となる。コンビナトリアルライブラリー技術は、有用物質の探索のための優れた先端テクノロジーとして期待されているが、方法論的に未完の部分が多い。本研究では、感染性心内膜炎の発症に関与する口腔細菌と生体組織との間の分子認識をモデル実験系として、この種のライブラリーを用いた細菌定着抑止物質の探索法とその効率を確保するための種々の用件を同定し、本方法論の実用化への道筋をつけた。
