{diamondsuit} Background: The micro-organisms involved in continuous ambulatory peritoneal dialysis (CAPD) peritonitis are usually gram-positive cocci of cutaneous origin. Campylobacter species are rarely implicated as a cause of CAPD peritonitis.

{diamondsuit} Methods: A retrospective review of 100 consecutive episodes of peritonitis was carried out in patients undergoing CAPD or automated PD in our hospital from June 2004 to December 2007. Collection of dialysate and microbial examination was done according to ISPD guidelines. Identification of the organism was made on the basis of Gram smear morphology, positive oxidase test, and biochemical reactions using API Campi (BioMérieux, Marcy l'Étoile, France). Susceptibility testing was performed using E-test (AB Biodisc, Solna, Sweden) and confirmation was done by molecular techniques.

{diamondsuit} Results: The causative organisms in 23 of these episodes were gram-negative bacteria, 3 of which were identified as Campylobacter species using special culture techniques. The clinical presentation in our patients with Campylobacter peritonitis (CP) was different from that of patients with peritonitis from other organisms in that all 3 had diarrhea at presentation. Among patients with CP, no subspecies-specific feature was identified. Good response to the antibiotic treatment was observed; there was no relapse/recurrence of peritonitis, catheter loss, or death.

{diamondsuit} Conclusion: Incidence of CP remains low and, regardless of the subtype, clinical outcomes are better than those seen with other gram-negative bacteria such as Pseudomonas. The presence of diarrhea at presentation and the finding of curved or spiral gram-negative bacilli in the Gram smear of peritoneal dialysis effluent should make one think of CP. The use of appropriate microbiology techniques in this situation will increase the isolation of this organism.
