Abstract:
We describe a case of recurrent peritonitis caused by Pseudomonas mesophilica in a diabetic man receiving continuous ambulatory peritoneal dialysis. Stagnant water on a bath rail used for support by the patient while showering was implicated as the probable source of these infections. We believe this to be the first report of the isolation of this water-associated bacterium in such infections.
Insights
Recurrent peritonitis in a diabetic patient on peritoneal dialysis was linked to Pseudomonas mesophilica. The probable source was stagnant bath water, marking the first report of this bacterium in such infections.
Area of Science:
- Infectious Diseases
- Nephrology
- Microbiology
Background:
- Continuous ambulatory peritoneal dialysis (CAPD) is a treatment for kidney failure.
- Peritonitis is a serious complication of CAPD.
- Pseudomonas species are known causes of CAPD peritonitis.
Observation:
- A diabetic patient on CAPD experienced recurrent peritonitis.
- The causative agent was identified as Pseudomonas mesophilica.
- Stagnant water on a bath rail was identified as the likely source.
Findings:
- This is the first report of Pseudomonas mesophilica causing peritonitis in a CAPD patient.
- The bacterium was isolated from the patient's peritoneal fluid.
- Environmental sampling implicated stagnant water as the reservoir.
Implications:
- Highlights the importance of environmental hygiene in CAPD patients.
- Suggests Pseudomonas mesophilica as a potential pathogen in CAPD-associated infections.
- Emphasizes the need for vigilance regarding water-associated bacteria in healthcare settings.
