Rhizobium radiobacter, a Rare Cause of Peritonitis

Rhizobium radiobacter is a Gram­‑negative bacteria known to cause peritonitis in peritoneal dialysis (PD) patients since 1985. Although it has low virulence, it is known to adhere to medical devices, raising concern for PD catheter removal. Currently, there are no guidelines as to the best practice when dealing with this agent, despite the growing number of published cases. We present a challenging and unexpected case of a 36­‑years­‑old male under PD who was diagnosed with Rhizobium radiobacter peritonitis.
