Granulicatella adiacens Endocarditis of a Bioprosthetic Aortic Valve

Infective endocarditis (IE) is relatively uncommon; however, when it diagnosed, usually among those with known cardiac valvular abnormalities. The most common pathogens that cause are streptococci (mainly viridans), enterococci, and other species. An extremely rare pathogen could IE Granulicatella. This gram-positive coccus classically inhabits human mucosal surfaces only rarely causes disease. We present an incredibly case of a 74-year-old female bioprosthetic aortic valve replacement, who presented headache weakness was subsequently found to have recurrent Granulicatella adiacens infective endocarditis.
