Native Aortic Valve Endocarditis Caused by Brevibacterium epidermidis in an Immunocompetent Patient

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.
