Late-Onset Prosthetic Endocarditis with Paraaortic Abscess Caused by .

, an integral component of the skin's customary bacterial flora, represents a Gram-positive anaerobic bacterium characterized by its low virulence. Despite its low virulence, the pathogen can cause profound-seated infections as well as infections linked to medical devices. We report a case study of a prosthesis endocarditis accompanied by a paraaortic abscess caused by , a development occurring five years prior to composite aortic root and valve replacement.
