Continuous ambulatory peritoneal dialysis complicated by Aureobasidium pullulans peritonitis.

We describe a case of peritonitis caused by Aureobasidium pullulans in a patient on continuous ambulatory peritoneal dialysis (CAPD). This dematiaceous fungus rarely causes infection in humans and to date has not been reported as an etiology of CAPD-associated peritonitis. The patient was managed successfully with peritoneal catheter removal and a prolonged course of intravenous amphotericin B, allowing resumption of CAPD. In vitro susceptibility testing confirmed sensitivity of this organism to amphotericin B.
