Comamonas testosteroni has rarely been implicated as a human pathogen. We here present a case of peritonitis due to this organism in a patient on continuous ambulatory peritoneal dialysis (CAPD). A 32-year-old woman was admitted with abdominal pain and cloudy peritoneal effluent. Empirical intraperitoneal (IP) treatment with cefazolin and ceftazidime was started. The culture was positive for C. testosteroni and antibiotic was changed to ceftazidime IP. Four days after the ceftazidime treatment, the patient became asymptomatic. The follow-up culture from peritoneal effluent at 7th day was negative. This treatment was maintained for 21 days. After that, culture negative peritonitis occurred twice for 2 months in this patient, so CAPD catheter had to be removed. This is the first reported case of CAPD peritonitis caused by C. testosteroni. It is important for clinicians to recognize that CAPD peritonitis is caused by this organism which has been largely overlooked as a potential pathogen.
