Successful treatment of peritonitis associated with Campylobacter fetus subspecies fetus in peritoneal dialysis patients: a case report and literature review.

Campylobacter fetus subspecies fetus was identified in the peritoneal dialysate of a 42-year-old patient undergoing continuous ambulatory peritoneal dialysis (CAPD). The patient initially received intraperitoneal ceftazidime and cefazolin sodium for 10 days, which led to significant symptom relief. However, bacterial cultures of the peritoneal dialysate remained positive. Further history revealed that the patient frequently dined at her father’s home, where turtles were kept, suggesting that turtle feces might be the source of infection. Subsequently, the treatment regimen was changed to oral amoxicillin-clavulanate potassium for 3 days, and the patient was advised to avoid contact with turtles. One week after discharge, follow-up cultures of the peritoneal fluid showed no bacterial growth. This case, combined with a review of the literature, provides valuable insights into the diagnosis and management of this rare infection.
