Peritoneal dialysis-related peritonitis due to Pasteurella multocida in Australia

Domestic animals are common in Australian households; however, there is little research into the potential risks these animals pose to patients undergoing in-home peritoneal dialysis (PD). Cats and dogs are known to carry many potential pathogens, including Pasteurella multocida. We reviewed the ANZDATA Peritoneal Dialysis Peritonitis Registry for cases of peritonitis due to Pasteurella multocida between 2011 and 2023. Cases identified were younger and more likely to be female compared with the Australian PD population who developed peritonitis due to other organisms. Of the total 32 episodes, 75% were using automated PD with glucose-based solutions. Two cases requiring removal of the PD catheter and transfer to haemodialysis and no deaths were reported. Whilst outcomes were largely favourable, it is likely that many of these cases could have been prevented. Education for people undergoing PD should include information about the potential infectious hazards of domestic animals.
