We describe a case of infective endocarditis due toMoraxella lacunata involving the native mitral and aorticvalves, complicated by cerebral emboli and resultanthemiparesis. The patient was treated with ceftriaxone andgentamicin and improved. This appears to be the first casereported in the medical literature of native multivalvularendocarditis produced by this rare organism.
