變形鏈球菌中的次級代謝產(chǎn)物及其在口腔生物被膜中的生態(tài)功能
[Abstract]:Oral biofilm is a complex microbial community composed of hundreds of microorganisms. Streptococcus mutans, as an important member, is considered to be the main cause of caries. The ability of Streptococcus mutans to grow in the form of biofilm on the tooth surface and its acidogenic and acidogenic characteristics endow it with caries. Different strains of Streptococcus mutans retain a variety of secondary metabolic forms, which is the result of long-term co-evolution with the host. Up to now, the secondary metabolites reported in Streptococcus mutans include 10 bacteriocins and one polyketone / non-ribosomal peptide. The various active forms of these compounds imply that they are involved in interspecies and cross-boundary interactions in oral biofilms. With the increase of the number of Streptococcus mutans strains and the completion of the whole genome sequence of more strains, it can be predicted that there will be more new active secondary metabolites. The study of secondary metabolism of Streptococcus mutans is not only helpful for the treatment and prevention of oral diseases, but also of great significance for the development of new drugs.
