Title: Streptococcus gordonii : Normal human oral flora      
ID:
PRJNA35081
description:
Streptococci. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. The genus is classified on the basis of colony morphology, hemolysis, biochemical reactions, and serologic specificity. They are divided into three groups by the type of hemolysis on blood agar plates: beta-hemolytic, alpha-hemolytic or gamma-hemolytic. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Streptococcus gordonii. This organism is a commensal member of the human oral flora. It initiates the formation of biofilms on tooth surfaces known as dental plaque, which is strongly associated with the development of dental cavities (caries) and gum disease. It is a frequent causative agent of bacterial endocarditis (inflammation of the membrane lining the heart) which often occurs as a result of oral trauma, allowing S. gordonii to invade the bloodstream and colonize the heart.
