Abstract

IntroductionOrganisms of the Streptococcus milleri group consists of Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus. Though they are commonly associated with abscesses, bacteremia with subsequent septic shock and mortality is infrequent.Case presentationWe report a case of a 27-year-old Chinese man who presented with Streptococcus constellatus bacteremia following an incomplete tooth extraction resulting in septic shock.ConclusionBacteremia from the Streptococcus milleri group is infrequent but must trigger the search for an underlying abscess. Knowledge of each member's predilection for different clinical presentations can aid in determining the location of the underlying source of infection.

Highlights

Organisms of the Streptococcus milleri group consists of Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus
Though they are commonly associated with abscesses, bacteremia with subsequent septic shock and mortality is infrequently described in the literature
Our patient illustrates the unusual presentation of severe septic shock from Streptococcus constellatus bacteremia

Summary

Conclusion

Our patient illustrates the unusual presentation of severe septic shock from Streptococcus constellatus bacteremia. The knowledge of the different clinical associations of S. intermedius, S. constellatus, and S. anginosus aid in the management of the patient in directing the search for an associated infection or occult abscess.
