Staphylococcus warneri endocarditis after implantation of a lumbar disc prosthesis in an immunocompetent patient.

In a 48-year-old immunocompetent man with recurrent fever since 21 months, endocarditis of the native aortic valve due to Staphylococcus warneri was diagnosed. Twenty-six months before, a prosthetic lumbar disc had been implanted in L 4/5. The lack of typical other infectious sources favours the hypothesis of a disc-prosthesis-induced bacteraemia.
