Together with Streptococcus constellatus
and Streptococcus intermedius
they constitute the anginosus group, which is sometimes also referred to as the milleri group after the previously assumed single but later refuted species Streptococcus milleri.
Streptococcus anginosus is part of the human bacteria flora, but can cause diseases including brain and liver abscesses under certain circumstances.

and Streptococcus intermedius
Streptococcus intermedius
Streptococcus intermedius is a commensal bacterium and a member of the Streptococcus anginosus group. The S. anginosus group, occasionally termed “Streptococcus milleri group” display hemolytic and serologic diversity, yet share core physiological traits. Despite being commensal organisms, members...
