Uncommon Pathogen, Common Complication: Rhizobium radiobacter- Induced Peritonitis in Peritoneal Dialysis

Rhizobium radiobacter is an uncommon opportunistic pathogen commonly found in soil. To date, only a few cases have reported R. radiobacter as a cause of PD-related peritonitis. Our patient developed R. radiobacter peritonitis after gardening, presenting with cloudy dialysate without pain or febrility. The infection was successfully treated with cefepime. However, it relapsed one month later, ultimately leading to catheter removal. Physicians must remain vigilant for this rare pathogen despite the much more common causes of peritonitis. Education of patients about the connection between Rhizobium radiobacter, soil exposure, and non-sterile conditions is crucial for prevention of relapses and avoiding the need for catheter removal.
