chelonae-like organism) is a recently characterized, rap-idly growing, atypical nontuberculous mycobacterium (NTM) that occasionally causes human infection (1). We present a patient on continuous ambulatory peritoneal dialysis (CAPD) who experienced peritonitis because of an atypical mycobacterium identified as m. mucogenicum. A 52-year-old diabetic man on CAPD (2.5-L exchanges 3 – 4 times daily) for 3.5 years presented with nausea, vomiting, abdominal pain, and altered sensorium for 2 days, together with cloudy effluent. He had a history of left ventricular failure, with intermittent atrial fibrilla-tion, and of 6 previous episodes of peritonitis (recurrent gram-negative Escherichia coli peritonitis, and 1 episode of Staphylococcus aureus peritonitis), which were success-fully treated. He weighed 98 kg
