A Case Report of Pasteurella multocida Peritoneal Dialysis-Related Peritonitis: Your Pet Cat May Be a Source of Disease!

Background: Pasteurella multocida is a gram-negative coccobacillus commonly found in the oropharyngeal flora of various animals, including domestic pets such as cats and dogs. Transmission of Pasteurella to humans usually occurs through close contact and can cause soft tissue infections, pneumonia, peritonitis, and meningitis. Case Report: We present a case of peritonitis in a 52-year-old male patient who had been undergoing home peritoneal dialysis for four years due to chronic renal failure. Peritoneal fluid culture identified the causative agent as P. multocida using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Upon analyzing the patient's medical history, it was determined that the patient had a pet cat. It was hypothesized that close contact with the cat and contamination of dialysis equipment were the likely sources of transmission. Conclusion: Educating patients at risk about the dangers of pet contact is crucial for preventing P. multocida-related peritonitis.
