项目摘要
In this study, I showed that chlorhexidine gluconate (CHX) and cetylpyridinium chloride (CPC) were effective against Porphyromonas gingivalis cells in biofilm, but extracellular matrix remained in biofilm after CHX and CPC application. In addition, extracellular matrix remained after CHX application was difficult to eliminate mechanically, suggesting that remaining extracellular matrix provides a scaffold for biofilm reformation.
在这项研究中,我表明,氯己定(CHX)和西酰吡啶丁基(CPC)在生物膜中有效抗性卟啉单胞菌细胞,但在CHX和CPC后,生物膜中仍保留了细胞外基质。此外,在施用CHX之后,难以机械消除CHX后仍保留细胞外基质,这表明剩余的细胞外基质为生物膜改革提供了脚手架。

A Porphyromo nas gingivais mutant defective in a putative glycosyltransferase exhibits defective biosynthesis of the polysac charide portions of lipopolysacharide, decreased gingipain activities, strong autoaggregation, and increased biofilm formation.
