Successful treatment of Prototheca peritonitis complicating continuous ambulatory peritoneal dialysis.

We describe the second reported case of peritonitis caused by the alga Prototheca wickerhamii in a patient on continuous ambulatory peritoneal dialysis (CAPD). This organism, which grows slowly on agar media, is recognised as a race cause of other infections. The condition is clinically similar to cases of fungal peritonitis, but there are important differences, particularly when choosing the best treatment.
