Abstract

バンコマイシン(VCM)耐性黄色ブドウ球菌(VRSA)とVCMヘテロ耐性黄色ブドウ球菌(ヘテロVRSA)について,VCMに対する耐性メカニズムをVCM感性黄色ブドウ球菌(VSSA)と比較した結果,両者とも細胞壁合成系の亢進が確認された。この細胞壁合成系の亢進がVCM耐性の要因の1つであると考えられる。また,VRSAの細胞壁中にのみ散在するVCM結合可能なD-Ala-D-Ala(ヘテロVRSAとVSSAには存在しない)がVCMを消費し,本来の標的部位までの到達を妨げるため,VRSAはヘテロVRSAよりもVCM耐性が増強していると考えられる。また,ヘテロVRSAは見かけ上VCM感性菌であり,既存の検出方法では検出できない。しかし,ヘテロVRSAはVCMとβ-lactam剤の併用で拮抗が起きる特徴があるため,この現象を利用した検出方法を考案した。
