[Polymicrobial endocarditis. Report of a case and review of the literature].

We describe a case of polimicrobial endocarditis in a patient with congenital aortic stenosis and end-stage renal failure in treatment with steroids and chronic haemodialisis. The blood culture grew e.coli, enterobacter sp, and s.epidermidis. Only a few papers in the literature have been devoted to this entity. Its frequency seems to be progressively higher. The present case is a good example to talk about the predisponent factors. The review of literature has shown that the occurrence of this entity is specially high among addicts, the most frequent bacteria are s.aureus, streptococci and pseudomonas and the mortality can be as high as 80%.
