Peritonitis due to Staphylococcus sciuri in a patient on continuous ambulatory peritoneal dialysis.

Among the coagulase-negative staphylococci, Staphylococcus sciuri has rarely been described as the aetiology of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. It has been reported in 1 case of endocarditis and has been isolated from peritoneal dialysis fluid in 2 patients. The case reported here describes CAPD peritonitis due to S. sciuri shortly after a previous episode due to S. aureus, showing the necessity to identify coagulase-negative staphylococci to find new species that cause CAPD peritonitis.
