Methodological variations in the isolation of genomic DNA from Streptococcus bacteria

Brazilian Archives of Biology and Technology, 2010
In this work, genomic DNA of Streptococcus pyogenes, S. mutans and S. sobrinus was isolated using two methods: either using the detergent cetyltrimethylammonium bromide (CTAB) at 65ºC; or by applying ultrasound to a mixture of silica and celite in CTAB ...

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, Volume 13, Issue 36, 29 June 2026.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Four gbpC Gene Homologues in Streptococcus sobrinus [PDF]

Journal of Oral Biosciences, 2007
We previously identified the glucan-binding protein C gene, gbpC, solely involved in dextran-dependent aggregation (ddag) of Streptococcus mutans. Recently, we identified two gbpC gene homologues, gbpC and dbl, in Streptococcus sobrinus, and suggested that the dbl gene was very likely responsible for ddag of this species.

Onosma armenum Extract Loaded Mesoporous Silica Nanoparticles for the Prevention of Biofilm‐Associated Infections

ChemistryOpen, Volume 15, Issue 4, April 2026.
Bioactive mesoporous silica nanoparticles (MSNPs) loaded with O. armenum extract were developed to evaluate their antibiofilm activity against biofilm‐forming Staphylococcus aureus ATCC 25923. The phytochemical content of the extract was analyzed via liquid chromatography–electrospray ionization tandem mass spectrometry.
