Role of HtrA in surface protein expression and biofilm formation by Streptococcus mutans.
The HtrA surface protease in gram-positive bacteria is involved in the processing and maturation of extracellular proteins and degradation of abnormal or misfolded proteins. Inactivation of htrA has been shown to affect the tolerance to thermal and environmental stress and to reduce virulence. We found that inactivation of Streptococcus mutans htrA by gene-replacement also resulted in a reduced...

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 کامل[Assessment of gene associated with Streptococcus mutans biofilm formation].
Streptococcus mutans, the primary etiological agent of human dental caries and an obligate biofilm-forming bacterium, has developed a variety of mechanisms to colonize the tooth surface. Oral transmission of S. mutans through contact between mother and child is thought to be one of the risks of developing dental caries. In this study, I surveyed oral transmission frequency of S. mutans from mot...
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 کاملLactobacillus plantarum lipoteichoic acid inhibits biofilm formation of Streptococcus mutans
Dental caries is a biofilm-dependent oral disease and Streptococcus mutans is the known primary etiologic agent of dental caries that initiates biofilm formation on tooth surfaces. Although some Lactobacillus strains inhibit biofilm formation of oral pathogenic bacteria, the molecular mechanisms by which lactobacilli inhibit bacterial biofilm formation are not clearly understood. In this study,...
