We report a case of non-complicated endocarditis due to nontoxigenic Corynebacterium diphtheriae that occurred on a native valve. The patient had no known risk factors for endocarditis, but he had poor social circumstances. He received penicillin in conjunction with an aminoglycoside therapy. Evolution was marked by the sterilization of blood cultures but persistence of small vegetation with mild mitral regurgitation. The patient was discharged and followed in consultation twice per month during 3 months and twice year after with good clinical and biological status.
