Infective endocarditis associated with Bartonella henselae: A case series

Organisms in the genus Bartonella are cause of blood culture-negative endocarditis. Bartonella infective endocarditis is being increasingly reported worldwide; however, reports from Japan are limited. Here, we report five cases of infective endocarditis associated with Bartonella henselae. All patients had a history of contact with cats or fleas; this information helped achieve an appropriate diagnosis. Keywords: Infective endocarditis, Blood culture-negative endocarditis, Bartonella henselae, Infection, Bartonella, Endocarditi
