[Lethal aortic endocarditis due to Gemella morbillorum in a Djiboutian khat user].

We report a 22-year-old man who presented in January 2009 in Djibouti for an aortic-abscessed endocarditis due to Gemella morbillorum (G. morbillorum). A voluminous aortic abscess that extended to the perimembranous ventricular septum was fistulized into the right atrium. Atrioventricular conduction abnormalities were observed. The portal of entry was dental with multiples caries and a periodontitis attributed to khat chewing. The patient died within few days. Diagnosis, severity and management of endocarditis due to this rare bacterium are discussed.
