There is Bartonella henselae（B. henselae） leads to cat-scratch disease and causes infective endocarditis, but shows as negative in blood cultures. We performed aortic valve replacement in a patient with aortic valve infective endocarditis which was regative on blood cultures. The patient had a contact history with a cat prior to admission. Thus, we suspected B. henselae and made a definitive diagnosis by PCR method and Warthin-Starry（WS）stain. A correct diagnosis was possible by detailed history taking and the use of appropriate antibiotics.
