A quantitative method to determine glycocalyx production by strains of viridans group streptococci from patients with endocarditis is presented. There is good correlation between this new tryptophan quantitative assay and qualitative assays employing polysaccharide stains (ruthenium red, periodic acid-Schiff, and Cellufluor) or the Molisch test. The quantification of the glycocalyx production in glucose substrate in vitro by viridans group streptococci correlates with the size of cardiac vegetation and ease of antimicrobial sterilization in experimental endocarditis. The relationship of in vitro quantification of glycocalyx to maintenance of infection, morbidity of infection, and antimicrobial treatment is discussed.
本文介绍了一种定量测定心内膜炎患者草绿色链球菌菌株糖萼生成量的方法。这种新的色氨酸定量测定法与采用多糖染色法(钌红、过碘酸-希夫反应和纤维素荧光素)或莫利希试验的定性测定法之间具有良好的相关性。草绿色链球菌在体外葡萄糖底物中糖萼生成量的定量与实验性心内膜炎中心脏赘生物的大小以及抗菌药物杀菌的难易程度相关。文中还讨论了糖萼体外定量与感染维持、感染发病率及抗菌治疗之间的关系。
