About

Enterococcus faecalis is a germ frequently responsible for bacteremia which can be severe with 15-25% risk of mortality and 26% risk of infectious endocarditis. There is no recommendation for the treatment of "simple" Enterococcus faecalis bacteremia (meaning without infectious endocarditis at diagnosis), nor studies comparing monotherapy versus combination antibiotic therapy.

Our main objective is to study the impact on mortality of bacteriostatic monotherapy and bactericidal combination antibiotic therapy in patients with Enterococcus faecalis bacteremia. We aim to also study the mortality up to three months, the failures of treatment, the modalities of treatment, the renal toxicity and the bacterial resistance.
