title: Native valve endocarditis due to Micrococcus luteus: a case report and review of the literature.
abstract: BACKGROUND
  Micrococcus luteus endocarditis is a rare case of infective endocarditis. A total of 17 cases of infective endocarditis due to M luteus have been reported in the literature to date, all involving prosthetic valves. To the best of our knowledge, we describe the first case of native aortic valve M luteus endocarditis in an immunosuppressed patient in this report.
  
  
  METHODS
  A 74-year-old Greek-Cypriot woman was admitted to our Internal Medicine Clinic due to fever and malaise and the diagnosis of aortic valve M luteus endocarditis was made. She was immunosuppressed due to methotrexate and steroid treatment. Our patient was unsuccessfully treated with vancomycin, gentamicin and rifampicin for four weeks. The aortic valve was replaced and she was discharged in good condition.
  
  
  CONCLUSIONS
  Prosthetic infective endocarditis due to M luteus is rare. To the best of our knowledge, we report the first case in the literature involving a native valve.
