Native aortic valve endocarditis caused by Brevibacterium epidermidis in an immunocompetent patient.

Abstract Although Brevibacterium species used to be considered as nonpathogenic microorganisms until recently, it seems that they can cause a wide variety of clinical diseases by acting mostly as opportunistic pathogens. The present case is the second reported case of infective endocarditis by Brevibacterium species; however, it is the first reported infected native aortic valve in an immunocompetent patient.
