Serratia marcescens (SM) is an opportunistic Gram-negative bacterium. It can cause technique failure or severe sepsis despite being a rare agent causing peritonitis. We present a case of a 40-year-old woman with end-stage renal disease secondary to chronic glomerulo-nephritis on continuous ambulatory peritoneal dialysis (PD). She presented with severe abdominal pain and a cloudy peritoneal fluid. The fluid was cultured according to our unit protocol. The organism isolated was identified as SM; this was after the patient was treated for SM peritonitis one week earlier. The response to treatment with ceftazidime was poor despite being sensitive in vitro. The peritoneal catheter was removed due to rapid clinical deterioration. Piperacillin-tazobactam (PIP/TAZ) monotherapy was successfully administered subsequently. Eventually, she was transferred to hemodialysis (HD). SM is an uncommon cause of PD-related peritonitis. It may cause catheter loss and even death. In our case, the infection could be controlled only after catheter removal, and she was transferred to HD. Cephalosporins should rapidly be changed to PIP/TAZ when SM is isolated from the peritoneal fluid.
