Dextranase enhances nanoparticle penetration of <i>S. mutans</i> biofilms. [PDF]

J Oral Microbiol
Cariogenic biofilms possess a rich extracellular polysaccharide (EPS) matrix, which can reduce the penetration of anticaries agents such as nanoparticle-based technologies. The aim of this study was to assess the potential of dextranase, an EPS-degrading enzyme, to enhance nanoparticle penetration into Streptococcus mutans in vitro biofilms ...

Proline-rich protein from S. mutans can perform a competitive mineralization function to enhance bacterial adhesion to teeth [PDF]

Scientific Reports, 2022
A proline-rich region was found in Streptococcus mutans (S. mutans) surface antigen I/II (Ag I/II). The functions of this region were explored to determine its role in the cariogenic abilities of S.

Norspermidine changes the basic structure of S. mutans biofilm. [PDF]

Mol Med Rep, 2017
The factors regulating the assembly of the three-dimensional structure of Streptococcus mutans biofilms remain obscure. Polyamines are essential in biofilm formation of certain bacteria. Norspermidine, an unusual polyamine, has been a controversial polyamine that can lead to biofilm disassembly. However, the role of norspermidine in S.

SloR-SRE binding to the <i>S. mutans mntH</i> promoter is cooperative. [PDF]

J Bacteriol
ABSTRACT Streptococcus mutans is a commensal member of the plaque microbiome. It is especially prevalent when dietary sugars are available for S. mutans fermentation, generating acid byproducts that lower plaque pH and foster tooth decay.

Characteristics and influencing factors of amyloid fibers in S. mutans biofilm. [PDF]

AMB Express, 2019
There are signs that amyloid fibers exist in Streptococcus mutans biofilm recently. However, the characteristics of amyloid fibers and fibrillation influencing factors are unknown. In this study, we firstly used transmission electron microscopy (TEM) and atomic force microscopy (AFM) to observe the morphology of amyloid fibers in S. mutans.

Streptococcus mutans exacerbates gut microbiota dysbiosis in SHANK3 -/- autism model mice via the oral-gut axis [PDF]

Journal of Oral Microbiology
Background and objective Autism spectrum disorder (ASD) is associated with gut microbiota dysbiosis, yet the impact of oral pathobiont translocation via the oral–gut axis remains unclear. This study investigated how Streptococcus mutans (S.

cnm-positive Streptococcus mutans is associated with galactose-deficient IgA in patients with IgA nephropathy.

PLoS ONE, 2023
The presence of Streptococcus mutans expressing Cnm protein encoded by cnm (cnm-positive S. mutans) in the oral cavity is associated with immunoglobulin A (IgA) nephropathy (IgAN). However, the precise mechanism by which cnm-positive S.
