title: Propionibacterium acnes as a cause of prosthetic valve aortic root abscess.
abstract: Propionibacterium acnes isolates usually have relatively low virulence and are often classified as contaminants when isolated from blood and tissue cultures. We report a patient with Propionibacterium acnes bacteremia and late prosthetic valve endocarditis, complicated by an aortic root abscess.
