The pseudo-taxonomic term Streptococcus viridans is often used to refer to this group of species, but writers who do not like to use the pseudotaxonomic term (which treats a group of species as if they were one species) prefer the terms viridans streptococci,[1] viridans group streptococci (VGS), or viridans streptococcal species. • These species possess no Lancefield antigens.[2] In general, pathogenicity is low.[3] • • Streptococcus vidridans full lecture in details • Long chain appearance,Clinical Manifestations, Laboratory Diagnosis
