Comamonas testosteroni (C. testosteroni) has been rarely observed as an infectious agent in clinical practice. Few reports described its potential pathogenicity in bloodstream and abdominal infections. Here, we report our experience in the treatment of a C. testosteroni-associated peritonitis in a four-year-old girl receiving chronic peritoneal dialysis (PD). The organism was shown to be highly susceptible to appropriate antibiotic therapy. Infection responded promptly and the patient was managed conservatively without withdrawal from PD.
Core tip:Comamonas testosteroni (C. testosteroni) has been largely overlooked as a potential pathogen in humans. This case reports not only the first description of a C. testosteroni-associated peritonitis in a pediatric patient, but also emphasizes the risk of uncommon causes of bacterial peritonitis especially in peritoneal dialysis children with severe comorbidities.
