Streptococcus milleri group

Streptococcus milleri is the name of a no longer recognized species of the bacteria genus Streptococcus. The name goes back to Otto Guthof, the Streptococcus milleri 1956 erstbeschrieb. He defined it as non- haemolytic, hydrolyze from purulent abscesses of the oral cavity isolated streptococci, the arginine and esculin and grow at 45 ° C on bile agar, but can not metabolize sorbitol and mannitol.

In more recent molecular biological studies have shown that Streptococcus milleri is not a separate species, but that the isolates designated as attributable to one another closely related species Streptococcus anginosus, Streptococcus intermedius and Streptococcus constellatus. These are therefore referred to as Streptococcus milleri Streptococcus anginosus or group.
