Peptostreptococcus infective endocarditis and bacteremia. Analysis of cases at a tertiary medical center and review of the literature.

Peptostreptococcus infective endocarditis is rare but associated with high morbidity. We report two cases and evaluate all positive blood cultures for Peptostreptococcus at our institution, followed by a review of the literature. This organism causes a subacute presentation and cardiac valve pathology is a risk factor. Penicillin remains the treatment of choice.
