Antibody binding to Streptococcus mitis and Streptococcus oralis cell fractions [PDF]

Archives of Oral Biology, 2008
To determine which cell fraction(s) of Streptococcus mitis biovar 1 serve as the best source of antigens recognized by salivary SIgA antibodies in infants.Whole cells of 38 reference and wild-type isolates of S. mitis, Streptococcus oralis, Streptococcus gordonii, Enterococcus casseliflavus, and Enterococcus faecalis were fractionated into cell walls ...

Defining antibody targets in Streptococcus oralis infection [PDF]

Infection and Immunity, 1996
Immunoblotting of sera from 12 neutropenic patients with Streptococcus oralis septicemia and 18 patients with endocarditis due to viridans group streptococci revealed immunodominant S. oralis antigens at 85 and 180 kDa. The former cross-reacted with a mouse monoclonal antibody to hsp90.

Bidirectional effects of neutrophils on Streptococcus oralis biofilms in vitro. [PDF]

J Oral Microbiol
Streptococcus oralis is a commensal bacterium and an early biofilm coloniser found in the human oral cavity. One of the biofilm matrix constituents is bacterial extracellular DNA (eDNA). Neutrophils are innate immune cells that respond to biofilms, employing antimicrobial mechanisms such as neutrophil extracellular trap (NET) and reactive oxygen ...

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.

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

Molecules, 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

Streptococcus gallinarum sp. nov. and Streptococcus oralis sp. nov. [PDF]

International Journal of Systematic Bacteriology, 1982
A numerical taxonomic survey of numerous strains of streptococci showed the presence of two clusters of strains that are distinct from the presently named species of Streptococcus. One group, from chicken intestines, is named S. gallinarum and the other, from the human mouth, is named S. oralis.
