Streptococcus Intermedius
''Streptococcus intermedius'' is an aerotolerant anaerobic commensal bacterium and a member of the ''Streptococcus anginosus'' group. The ''S. anginosus'' group, occasionally termed “''Streptococcus milleri'' group” (SMG) display hemolytic and serologic diversity, yet share core physiological traits. Despite being commensal organisms, members of the ''S. anginosus'' group display wide pathogenic potential. ''S. intermedius'' has been isolated from patients with periodontitis and fatal purulent infections, especially brain and liver abscesses.Claridge, J. E., III, S. Attorri, D. M. Musher, J. Hebert, and S. Dunbar. 2001. ''Streptococcus intermedius'', ''Streptococcus constellatus'', and Streptococcus ''anginosus'' (“''Streptococcus milleri'' group”) are of different clinical importance and are not equally associated with abscess.

Streptococcus Anginosus Group
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. They have been implicated as etiologic agents in a variety of serious purulent infections, but because of their heterogeneous characteristics, these organisms may be unrecognized or misidentified by clinical laboratorians. The unique characteristic of them from other pathogenic streptococci, such as ''S. pyogenes'' and ''S. agalactiae'', is their ability to cause abscesses.
