Investigating the Role of Invasive Streptococcus Constellatus Infection in Severe Systemic Disease Manifestations: A Case Report.

We hope to add to the literature evidence regarding the increasing morbidity associated with an invasive infection by a normal body commensal,  (). An increasing amount of literature documentation of intra- and extracranial disease manifestations following a systemic infection by this micro-organism is noted. We describe the findings of severe, necrotizing right lung disease and possible septic brain emboli in a 54-year-old gentleman in whom microbiological investigations suggest , and mixed anaerobes as possible culprit micro-organisms causing his severe disease state.
