Peritonitis with CDC group IVc-2 bacteria in a patient on continuous ambulatory peritoneal dialysis.

A case of CDC group IVc-2 peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD) is described. To the authors' knowledge, this is the first case reported of CAPD peritonitis in which a member of this unusual group of bacteria was isolated as the sole microorganism. As this microorganism is usually resistant to most antibiotics commonly used to treat peritonitis in patients on CAPD, microbiological investigations with identification and antimicrobial susceptibility tests are mandatory.
