生物膜是嵌入细胞外基质中的微生物群落,形成高度组织化的结构,导致许多人类感染。龋齿(蛀牙)是一种由饮食和固体表面上发生的微生物-基质相互作用驱动的多微生物生物膜疾病。糖促进了病原体的出现、基质的组装和生物膜微环境的酸化,促进了生态变化和多物种的协同努力,这有助于矿化牙齿组织的酸损伤。在这里,我们讨论了生物膜基质的作用和龋齿的发病机制中的机会致病菌和微生物之间的相互作用的最新进展。此外,我们强调了产生基质的生物体在培养病原体栖息地方面的重要性,在该栖息地中,种间竞争和协同作用发生以驱动疾病过程,这可能对与多微生物生物膜相关的其他感染产生影响。
Biofilms are microbial communities embedded within an extracellular matrix, forming a highly organized structure that causes many human infections. Dental caries (tooth-decay) is a polymicrobial biofilm disease driven by the diet and microbiota-matrix interactions that occur on a solid surface. Sugars fuel the emergence of pathogens, the assembly of the matrix, and the acidification of the biofilm microenvironment, promoting ecological changes and concerted multispecies efforts that are conducive for acid damage of the mineralized tooth tissue. Here, we discuss recent advances on the role of the biofilm matrix and interactions between opportunistic pathogens and commensals in the pathogenesis of dental caries. In addition, we highlight the importance of matrix-producing organisms in fostering a pathogenic habitat where inter-species competition and synergies occur to drive the disease process, which could have implications to other infections associated with polymicrobial biofilms
