Peritonitis caused by gram-negative organisms is a significant complication encountered in patients undergoing peritoneal dialysis and is associated with high morbidity and mortality. There has been recognition of peritonitis caused by uncommon organisms because of improved microbiological detection techniques. In this article, we report a rare case of peritonitis caused by Pasteurella multocida. We present a 58-year-old male on peritoneal dialysis with fever and abdominal pain. The peritoneal fluid was cloudy, and the analysis was consistent with peritonitis. The peritoneal fluid culture grew Pasteurella multocida. The patient was treated with a 3-week course of intraperitoneal ceftazidime, which resulted in the resolution of infection with the salvation of the peritoneal dialysis catheter. Patient education plays a very critical role in the prevention of peritonitis from Pasteurella multocida, particularly if patients have pets at home. The domestic pets should be kept away from the dialysis equipment and should not be allowed into the room during dialysis treatment. Incorporating the education in handing pets during the training session is the key aspect.
