Background:
Peritonitis continues to be a major problem for peritoneal dialysis patients. The incidence of peritonitis has decreased in recent decades but uncommon organisms are inceasingly being reported.
Case report:
We report an 83 year old man with history of diabetes mellitus, arterial hypertension, coronary artery disease and end stage renal disease on peritoneal dialysis, who developed recurrent peritonitis due to simultaneous presence of two uncommon organisms, Pasturella multocida and Capnocytophag. The patient was treated with antibiotics but he did not respond well and therefore his peritoneal dialysis catheter was removed. We discuss the microbiology of both organisms and review the literature.
Conclusions:
Peritonitis is a major problem for peritoneal dialysis patients and although improved technology has decreased the incidence of peritonitis, unusual organisms are increasingly reported. Pet owners who are on peritoneal dialysis, should be aware of the risks of association with animals.
