The First Case of Native Mitral Valve Endocarditis due to Micrococcus luteus and Review of the Literature

الملخص EN

Gram-positive cocci species, notably Staphylococcus, Streptococcus, and Enterococcus account for 80 to 90% of infective endocarditis cases.

HACEK microorganisms (Haemophilus spp., Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) account for approximately 3% of cases and Candida species account for 1-2% of cases.

Micrococcus luteus is a rare cause of endocarditis.

To our knowledge, only 17 cases of prosthetic valve endocarditis have been described due to M.

luteus and a single case of native aortic valve endocarditis has been described.

The following case is the only documented case of native mitral valve endocarditis.

A review of the literature pertaining to Micrococcus endocarditis was performed to further characterize the entity.
