A Case Report of Aerococcus urinae Prosthetic Valve Infective Endocarditis Initially Misidentify

Abstract

Infective endocarditis (IE) is most commonly caused by species such as staphylococci, streptococcus and enterococci. When IE is caused by organisms such as Aerococcus urinae, misidentification of the organism in culture is common, resulting in misdiagnosis. We present a case of IE caused by Aerococcus urinae in a 67-year-old male with a bioprosthetic aortic valve whose culture initially grew micrococcus.
