Molecule Targeting Glucosyltransferase Inhibits Streptococcus mutans Biofilm Formation and Virulence

, 2016
Dental plaque biofilms are responsible for numerous chronic oral infections and cause a severe health burden. Many of these infections cannot be eliminated, as the bacteria in the biofilms are resistant to the host's immune defenses and antibiotics ...

Insights Into the Antibiofilm Activity of Carbon Quantum Dots Against a Panel of Different Microorganisms: A Review

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carbon quantum dots (CDs) have emerged as versatile nanoplatforms for combating biofilm‐associated infections through multiple mechanisms, including EPS disruption, membrane damage, ROS generation, and quorum sensing inhibition. This review highlights how CD physicochemical properties and surface engineering strategies influence antibiofilm activity ...

Differential Regulation of Streptococcus Mutans Glucosyltransferases Gtf B/C/D Genes in Response to Copper Ions

, 2008
To persist in the oral cavity, bacteria must be able to tolerate environmental fluctuation, particularly in pH, nutrients, and essential elements. Glucosyltransferases B, C , and D of Streptococcus mutans synthesize glucans, and play essential roles in ...

Identification of a Nonribosomal Peptide Analog With Activity Against Multiple Gram‐Positive Bacteria via a Synthetic Bioinformatic Natural Product Discovery Approach

Advanced Science, Volume 13, Issue 50, 7 September 2026.
The genome of Rhodococcus erythropolis D‐1 was analyzed by bioinformatic tools to mine a novel nonribosomal peptide synthetase (NRPS) gene cluster. A nonribosomal peptide analog ZURJC5 associated with the NRPS was chemically synthesized. Through structure‐activity relationship studies, ZURJC28 was ultimately obtained and showed antibacterial activity ...

Genetic and Phenotypic Analysis of Genes Involved in Bacitracin Resistance in Streptococcus mutans

, 2012
Streptococcus mutans is considered to be the primary causative agent of dental caries in humans. In the oral cavity, S. mutans frequently exposed to antimicrobial compounds secreted from competing species and from the host.

A Blood‐Derived Double‐Network Hydrogel with Robust Wet Adhesion for Keratinized Mucosa Regeneration via Neutrophil Phenotype Reprogramming and Mechanophysical Niche Modulation

Advanced Science, Volume 13, Issue 51, 14 September 2026.
The iPRF‐MA/Alg‐NHS/Lut@EGCG (PGAE) double‐network hydrogel achieves durable wet adhesion in the oral environment. It simultaneously reprograms neutrophils from NETosis to phagocytosis for biofilm clearance, and activates the FAK‐RhoA‐YAP mechanotransduction pathway in gingival fibroblasts to drive extracellular matrix remodeling, thereby promoting ...

The Oral Microbiome of King Richard III of England

American Journal of Biological Anthropology, Volume 191, Issue 1, September 2026.
ABSTRACT Objectives Metagenomic investigations of ancient dental calculus provide insights into oral health, disease, and diet. Here, we analyze the dental calculus metagenome of King Richard III of England (1452–1485). Materials and Methods Dental calculus DNA was extracted from three teeth of King Richard III and shotgun sequenced to a depth of ...
