ABSTRACT: Granulicatella adiacens (G. adiacens), formerly classified as a nutritionally variant streptococci (NVS), is a commensal organism in the mouth. It is known to be a rare cause of infective endocarditis (IE). This case report presents a case of IE caused by G. adiacens in a 63-year-old man with mitral valve prolapse (MVP), severe mitral regurgitation (MR), and dual vessel disease (DVD). G. adiacens was isolated from two of three blood cultures, and the organism was sensitive to penicillin, vancomycin, cefotaxime, and gentamicin. He was successfully treated with a combination of ceftriaxone and gentamicin. Prompt identification of the organism and determination of antibiotic sensitivity pattern led to successful treatment. This case report showcases the challenges in diagnosis, and treatment, giving insight to healthcare providers on a rare entity.
