Peritoneal dialysis-related peritonitis remains a major complication of peritoneal dialysis in patients with end-stage renal disease. Chryseobacterium indologenes is a rare organism that has been reported to cause infections mostly in hospitalised patients with severe underlying diseases. We report the first case of C indologenes peritonitis in a patient on peritoneal dialysis outside of Asia. Our patient with end-stage renal disease on peritoneal dialysis grew C indologenes from peritoneal fluid when he presented with abdominal pain and cloudy effluent. The patient responded well to intraperitoneal antibiotic therapy. Tenckhoff catheter did not require removal. This case demonstrates the importance of considering rare causes of peritonitis, such as C indologenes, in patients on peritoneal dialysis. Given the resistance of such organisms to commonly used broad-spectrum antibiotics, antimicrobial susceptibility testing must be assessed as early as possible to assure appropriate antibiotic coverage to avoid untreated peritonitis leading to peritoneal dialysis failure.
