Streptococcus anginosus is a species of Streptococcus.[1] 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.
