title: A rare case of peritoneal dialysis-related peritonitis caused by goldfish water tankderived Aeromonas hydrophila.
abstract: METHODS
  A 62-year-old man was diagnosed with peritoneal dialysis (PD)-related peritonitis following diarrhea and determination of a dialysate leukocyte count of 10,224/μL. We cultured peritoneal effluent and started intraperitoneal antibiotic therapy. Peritonitis immediately improved. Peritoneal effluent culture yielded Aeromonas hydrophila. The medical interview revealed that the patient kept goldfish as pets. We suspected that the fish tank water was the source of the infection, considering the association of A. hydrophila with aquatic environments. Culturing of tank water confirmed the presence of Aeromonas. Furthermore, we observed that one of the goldfish was suffering from lepidorthosis, which is commonly caused by Aeromonas, and we then confirmed that the fish's infection was caused by an aeromonad.
  
  
  CONCLUSIONS
  Aeromonas species have rarely been identified as the pathogens in PD-related peritonitis; to our knowledge, there hitherto have been no reports identifying the source of this organism. We present here the process of this infection as elucidated through investigation of the living environment of the patient.
