Detection of Cardiobacterium valvarum in a patient with aortic valve infective endocarditis by broad-range PCR

Cardiobacterium valvarum , a fastidious Gram-negative bacterium, was detected in the aortic valve of a previously healthy 63-year-old man by broad-range PCR and 16S rRNA gene sequencing. In contrast to the patients in five previously published cases, our patient had neither a congenital bicuspid nor a prosthetic aortic valve. Here, we present a case of C. valvarum native tricuspid aortic valve infective endocarditis and a review of the...
