Prosthetic valve endocarditis due to Kocuria varians

摘要

Gram positive cocci were isolated from the blood culture of a 39 year old man with prosthetic valve endocarditis . He had a past history of aortic valve replacement 8 years ago and was now admitted to the hospital with a two week history of fever. The isolate was identified as Kocuria varians, an organism seen as a colonizer on the skin surface and formerly classified as Micrococcus species. To the best of our knowledge this is the first case report of prosthetic valve endocarditis due to Kocuria varians. Despite aggressive treatment, the patient died of neurological complications.
