Streptococcal anginosus infections (S. constellatus, S. anginosus, and S. intermedius) are characterized by their severity, linked to high mortality and frequent infectious complications. Several studies in the literature highlight this severity, with mortality rates estimated at around 15%.

The aim of this research is to identify the factors associated with mortality in Streptococcal anginosus bacteremia.
