		Streptococcus pneumoniae and viridans ("green") streptococci are α hemolytic.
		Group A streptococci in the absence of fibrinogen fix complement to the peptidoglycan layer and, in the absence of antibodies, are not phagocytosed.

	Relationship among sucrose, mutans streptococci and caries
		The purpose of this study was to investigate the relationship among frequency of sucrose exposure, mutans streptococci levels and dental caries.
		The data show that there was a tendency for higher counts of mutans streptococci in dental plaque and higher enamel mineral loss according to frequency of sucrose exposure.
		An increase of mutans streptococci would be expected according to sucrose exposure considering that a frequent low pH in dental plaque would be an ecological factor for its growth (4).

		The in vitro study revealed that streptococci from the mutans group were more susceptible to the bactericidal activity of the essential oil mouthrinse than streptococci from the mitis group.
		The streptococci were aggregated by parotid and whole saliva, and S. sanguis aggregation was less with whole saliva from the elderly than from the young participants.
		Major detachment of streptococci adhering to the substratum occurred when adhesion was mediated through a salivary conditioning film on the glass, while detachment of adhering actinomyces and streptococci co-adhering with them remained low.

		The number of salivary mutans streptococci was monitored for 11 wk after the gel treatment using both mitis-salivarius-bacitracin agar plates and the chairside method based on the adhesion of mutans streptococci on plastic strips (Dentocult-SM Strip mutans).
		In the groups receiving placebo varnish-sealant combinations, the mean log number of mutans streptococci of the subjects was reduced only by approximately 0.5 log (32%), and none of the subjects experienced loss of their detectable mutans streptococci for four weeks, although one subject did so for three weeks.
		Mutans streptococci on root surfaces were suppressed significantly (p less than 0.05) during the whole experimental period in the chlorhexidine varnish group, but not in the fluoride varnish group.

		Nearly all medically important streptococci have multiple nutritional requirements (auxotrophies) that include vitamins, amino acids, and nucleic acids, and are therefore not free-living in the environment.
		The most common classification system for streptococci used everyday in the clinical microbiology lab is based on the appearance of colonies grown on the surface of blood-agar media.
		The ß-hemolytic streptococci are further classified on the basis of a scheme developed by Rebecca Lancefield (1895-1981) that tests the serologic reactivity of carbohydrate antigens (C substance) derived from acid extraction of the bacterial cell walls.
