Salivary biotypes of mutans Streptococci levels in schoolchildren aging 6-8 year old having a socioeconomic base

Brazilian Journal of Oral Sciences, 2015
There is still little information on the mutans Streptococci biotypes in South America, specifically in Brazil, including regional and local information, associated to different socioeconomic categories. In this paper, the Streptococcus mutans levels and

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

233 nm far‐UV‐C radiation for biofilm inactivation

Photochemistry and Photobiology, EarlyView.
Based on tests to assess biofilm formation potential (crystal violet staining, color of colonies grown on Congo red agar and calcofluor agar), three bacterial genera/species/strains (Staphylococcus (S.) epidermidis, S. aureus, Pseudomonas (P.) aeruginosa) were selected for analysis of their biofilm matrix composition.

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 ...

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
