Peritonitis is a major cause of morbidity in continuous ambulatory peritoneal dialysis (CAPD) patients. Achromobacter xylosoxidans is a rarely reported cause of peritonitis in CAPD patients. In this report, a peritonitis case due to Achromobacter xylosoxidans in a 60-year-old male patient with end-stage renal failure receiving CAPD for 7 years, has been reported. White blood cell (WBC) count in peritoneal fluid was 3,160/mm3 with 95% neutrophil. Gram staining of the peritoneal fluid yielded gram negative rod. Empirical antibiotic therapy with ceftriaxone was initiated intraperitoneally. But drug sensitivity test revealed these regimens were resistant. On fourth hospital day, Achromobacter xylosoxidans was cultured from peritoneal effluent, the antibiotic regimen was switched to piperacillin/tazobactam intraperitoneally. The patient rapidly recovered and the WBC count of the peritoneal effluent decreased. The therapy was continued for 14 days and then the patient was discharged. The peritoneal catheter was not removed.
