Evaluation of the Antimicrobial Effect of Thymoquinone against Different Dental Pathogens: An In Vitro Study

open access: yesMolecules, 2021
This study aimed to evaluate the antimicrobial effect of Thymoquinone (TQ) on four different oral microorganisms. Minimum Bactericidal Concentration (MBC), Minimum Inhibition Concentration (MIC), Broth microdilution, and Well diffusion tests were used to

Potential of Prebiotic D-Tagatose for Prevention of Oral Disease

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Recent studies have shown phenotypic and metabolic heterogeneity in related species including Streptococcus oralis, a typical oral commensal bacterium, Streptococcus mutans, a cariogenic bacterium, and Streptococcus gordonii, which functions as an ...

Isolation and characterisation of sialidase from a strain of Streptococcus oralis [PDF]

open access: yesJournal of Medical Microbiology, 2000
Streptococcus oralis, the most virulent of the viridans streptococci, produces a sialidase and this exo-glycosidase has been implicated in the disease process of a number of pathogens. The sialidase of S. oralis strain AR3 was purified in order to understand the characteristics of this putative virulence determinant.

Infection of Streptococcus oralis NCTC 11427 by pneumococcal phages [PDF]

open access: yesFEMS Microbiology Letters, 1989
We have found a group of pneumococcal bacteriophages (Cp-1, Cp-7) that can successfully infect and replicate in Streptococcus oralis, whereas Dp-1 was unable to infect this species. We have also developed conditions that allowed transfection of S. oralis using Dp-1 DNA.

Highly Variable Streptococcus oralis Strains Are Common among Viridans Streptococci Isolated from Primates

open access: yesmSphere, 2016
Viridans streptococci were obtained from primates (great apes, rhesus monkeys, and ring-tailed lemurs) held in captivity, as well as from free-living animals (chimpanzees and lemurs) for whom contact with humans is highly restricted. Isolates represented

Construction of a DNA probe for the specific identification of Streptococcus oralis [PDF]

open access: yesJournal of Clinical Microbiology, 1988
A DNA probe for the specific detection and identification of Streptococcus oralis was isolated from HindII-digested DNA of S. oralis NCTC 11427 and cloned in Escherichia coli. The plasmid pOS1 hybridized only to DNA of S. oralis and not to that of other viridans group streptococci.

Antimicrobial Effects of Garcinia Mangostana on Cariogenic Microorganisms [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Garcinia mangostana commonly called as Mangosteen fruit has been used as an antibacterial agent since age old times. The mangosteen pericarp has proven to have antibacterial effect, but the effect of the same on cariogenic organisms has ...
