title: Infective endocarditis due to Streptococcus sanguis I occurring on a normal mitral valve.
abstract: We report a 64 year old lady in whom infective endocarditis of the mitral valve occurred with no previous underlying heart disease. Streptococcus sanguis I was isolated on blood culture and 2-D echo cardiography showed a vegetation on the anterior mitral leaflet. The viridans group of streptococci are classically associated with subacute endocarditis occurring on structurally abnormal valves, but involvement of a normal valve by these organisms is rare.
