streptococcus is a member of what group of organisms
- The Streptococcus anginosus group ( SAG ), also known as the anginosus group streptococci ( AGS ) or the milleri group streptococci ( MGS ), are a group of several species of streptococci with clinical similarities. The group is named after a principal member species, Streptococcus anginosus . The older name Streptococcus milleri (as well as Streptococcus milleri group, SMG) is now pseudotaxonomic, as the idea that these streptococci constituted a single species was incorrect. The anginosus group streptococci are members of the viridans streptococci group.
