Pet-Related Pasteurella Multocida-Induced Peritonitis in Peritoneal Dialysis: A Case Report

Abstract

Pasteurella multocida is a small, Gram-negative cocco-bacillus usually found in the oral cavities of most healthy cats and dogs as part of their natural oral flora. This zoonotic pathogen can cause a variety of infections in humans. The number of reported cases of peritoneal dialysis-associated peritonitis caused by P. multocida has been limited worldwide. We report here the case of a 38-year-old woman on continuous peritoneal dialysis (PD) that presented to the emergency department with abdominal pain and vomiting lasting for two days. A sample of peritoneal dialysis fluid was explored in the microbiology laboratory where grown microorganisms was identified by the VITEK2 system as P. canis with 90% accuracy. Then whole genome sequencing concluded that the species is rather P. multocida and that the strain was sensitive to all antibiotics tested and harbored various virulence genes. Patient was treated by intraperitoneal antibiotic course with cefotaxime for 3 weeks.
