A case of infective endocarditis (lE) in a 51/ 2-yearold boy in whom blood and bone marrow cultures yielded an unusual organism, a non-toxigenic strain of Corynebacterium diphtheriae, is reported. This proved fatal, and at autopsy congenital valvar aortic stenosis was found, but the vegetations occurred on an anatomically normal mitral valve. Organisms suchas C. diphtheriae should not be ignored when isolated from blood cultures in suspected cases of lE.
