The authors present a case of a patient undergoing continuous ambulatory peritoneal dialysis (CAPD) who developed peritonitis with Curvularia lunata and gram negative Enterobacteriaceae. A review of the literature indicates that human infections caused by Curvularia are uncommon despite the ubiquity of the organism in the environment. In this case, the organism was present in the Tenckhoff catheter, lacking attachment to it, but obstructing the flow. Treatment of fungal peritonitis during CAPD is discussed.
