Rare Case of Infective Endocarditis Due to Gemella Morbillorum in Patient with Bicuspid Aortic Valve

Abstract

Infective endocarditis caused by Gemella morbillorum is one of the rare causative microorganisms of endocarditis and only a few cases have been reported in the literature so far. We describe a case of Gemella morbillorum endocarditis in a 37-year-old Moroccan man who had a congenitally bicuspid aortic valve. He presented to our institution with a 1.5-month history of fever, and the onset of a motor deficit in the right hemibody one day prior to consultation. A transthoracic echocardiogram showed two large, echogenic and mobile vegetations (30×8 mm) with perforation of the left cusp and fistulized abscess of the anterior mitral leaflet measuring approximately 16x20mm. Blood cultures of the patient grew pan-sensitive Gemella morbillorum. The patient fulfilled the Duke’s criteria for infective endocarditis. The patient was successfully treated with antibiotics and aortic and mitral valves replacement.
