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.

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 ...

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.

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 ...

Molecular Relationships and Classification of Some Viridans Streptococci as Streptococcus oralis and Emended Description of Streptococcus oralis (Bridge and Sneath 1982) [PDF]

International Journal of Systematic Bacteriology, 1985
Nucleic acid hybridization studies together with a chemical cell wall analysis and physiological data indicated that some strains designated as Streptococcus sanguis II, Streptococcus sp. (“S. mitior”-S. sanguis), and “S. viridans” I, II, and IV are closely related to the type strain of S. oralis.
