Potential of Prebiotic D-Tagatose for Prevention of Oral Disease

Frontiers 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 ...

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

mSphere, 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

Re-evaluation of boundaries of <i>Streptococcus mitis</i> and <i>Streptococcus oralis</i> and demonstration of multiple later synonyms of <i>Streptococcus mitis, Streptococcus oralis</i> and <i>Streptococcus thalassemiae:</i> description of <i>Streptococcus mitis</i> subsp. <i>carlssonii</i> subsp. nov. and emended description of <i>Streptococcus mitis</i>. [PDF]

Int J Syst Evol Microbiol
The commensal species Streptococcus mitis and Streptococcus oralis are genetically diverse to a degree that challenges traditional definitions of species. This causes automatic identification based on DNA sequences or cellular extract profiles problematic.

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

Journal 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.

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

Journal 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.

Detection and expression analysis of tet(B) in Streptococcus oralis. [PDF]

J Oral Microbiol, 2019
Tetracycline resistance can be achieved through tet genes, which code for efflux pumps, ribosomal protection proteins and inactivation enzymes. Some of these genes have only been described in either Gram-positive or Gram-negative bacteria. This is the case of tet(B), which codes for an efflux pump and, so far, had only been found in Gram-negative ...

Susceptibility of cariogenic microorganisms to phytoconstituents

Brazilian Journal of Biology, 2018
This study aimed to evaluate the in vitro antibacterial activity of the phytochemicals thymol, linalool, and citronellol against Streptococcus mutans, Streptococcus salivarius and Streptococcus oralis.

Antimicrobial Effects of Garcinia Mangostana on Cariogenic Microorganisms [PDF]

Journal 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 ...

Mitis group streptococci express variable pilus islet 2 pili. [PDF]

PLoS ONE, 2011
Streptococcus oralis, Streptococcus mitis, and Streptococcus sanguinis are members of the Mitis group of streptococci and agents of oral biofilm, dental plaque and infective endocarditis, disease processes that involve bacteria-bacteria and bacteria-host
