PBP1a-Deficiency Causes Major Defects in Cell Division, Growth and Biofilm Formation by Streptococcus mutans
Streptococcus mutans, a key etiological agent of human dental caries, lives almost exclusively on the tooth surface in plaque biofilms and is known for its ability to survive and respond to various environmental insults, including low pH, and antimicrobial agents from other microbes and oral care products. In this study, a penicillin-binding protein (PBP1a)-deficient mutant, strain JB467, was g...
متن کاملBiofilm Formation by Streptococcus mutans and Related Bacteria
Caries is a disease of human dentition characterized by the loss of mineralized surfaces of the toot di non-specific removal of plaque by mechanical means such as brushing, although it is difficu this method. Caries is also a widespread infection in children. Streptococcus mutans and S. gents of caries heres to the en ria.
متن کاملMutation of luxS affects biofilm formation in Streptococcus mutans.
Quorum sensing is a bacterial mechanism for regulating gene expression in response to changes in population density. Many bacteria are capable of acyl-homoserine lactone-based or peptide-based intraspecies quorum sensing and luxS-dependent interspecies quorum sensing. While there is good evidence about the involvement of intraspecies quorum sensing in bacterial biofilm, little is known about th...
متن کاملEvaluation of inhibitory effects of Chlorella vulgaris extract on growth, proliferation and biofilm formation by Streptococcus mutans and evaluation of its toxicity
Background & Objectives: Dental caries is the most important disease caused by some bacteria specially Streptococcus Mutans from Viridans family. The aim of this study is to evaluate the inhibitory effect of Chlorella vulgaris extract on growth, proliferation, and biofilm formation of Streptococcus mutans. Materials & Methods: Microalgae Chlorella vulgaris was extracted via maceration using ch...
متن کاملEffects of manganese on Streptococcus mutans planktonic and biofilm growth.
Streptococcus mutans, an agent of dental caries, was tested for growth in the presence or absence of manganese (Mn), since studies have linked Mn levels with cariogenic potential. Seven S. mutans serotype c strains were grown in chemically defined medium under different atmospheric conditions: 5% CO2, O2-enriched 5% CO2 (shaking) and anaerobic. There was significant strain variability with resp...
