	Streptococcus viridans - Wikipedia, the free encyclopedia
		Viridans streptococcus is a pseudo-taxonomic term for a large group of generally non-pathogenic, commensal streptococcal bacteria that are either α-hemolytic and produce a green (hence the name viridans) coloration on blood agar plates, or non haemloytic.
		Viridans streptococci can be differentiated from Streptococcus pneumoniae using an optochin test, as Viridans Streptococci is optochin resistant.
		Viridans streptococci also lack either the polysaccharide-based capsule typical of S.

		The gene sequence for the circular chromosomes of twelves pecies of streptococci have been sequenced: Streptococcus pneumoniae, Streptococcus agalactiae 2603 V/R, Streptococcus mutans, Streptococcus thermophilus CNRZ1066, Streptococcus thermophilus LMG 18311, and Streptococcus pyogenes.
		The capsule of Streptococcus pyogenes is chemically similar to that of it's host's connective tissue, and therefore, is nonantigenic, and it's cytoplasmic membrane has antigens similar to human cardiac skeletal and smooth muscle.

		Among the viridans streptococci, production of the exopolysaccharide (glycocalyx) is associated with the ability to adhere to the cardiac valves and to form vegetations on the valve leaflets.

		Thus the "Mutans streptococci" were born and the name Streptococcus mutans was retained to describe the most common of the two main human strains, the other being called Streptococcus sobrinus.
