Abstract
Peritonitis remains a serious complication in patients undergoing peritoneal dialysis, often caused by common organisms such as Staphylococcus aureus. However, rare pathogens may also play a role. We report a case of peritonitis in a 41-year-old female on continuous ambulatory peritoneal dialysis, in whom Pluralibacter gergoviae was identified as the causative organism. The patient presented with abdominal pain and cloudy dialysate but remained hemodynamically stable. Peritoneal fluid analysis revealed elevated white cell counts, and culture Pluralibacter gergoviae, which was sensitive to multiple antibiotics. Initial empiric therapy was adjusted accordingly, leading to clinical and laboratory improvement. This is the second reported case of Pluralibacter gergoviae-related peritonitis in the literature. This case underscores the importance of recognizing uncommon pathogens in peritoneal dialysis-related infections and the role of prompt microbiological diagnosis in guiding targeted therapy. Increased awareness and reporting of such cases are essential to enhance understanding and optimize patient management.
