Mycobacterium fortuitum infection in continuous ambulatory peritoneal dialysis

Abstract

Mycobacterium fortuitum group species is an atypical rapidly growing nontuberculous mycobacterium. It has been increasingly recognized as a potential pathogen mostly encountered in skin and soft tissue infections. Rarely, however, it has been associated with catheter-related infections, either central venous lines or peritoneal dialysis catheters. In this report we describe 2 patients maintained on continuous ambulatory peritoneal dialysis who developed Mycobacterium fortuitum peritonitis and a catheter tunnel abscess, respectively. Molecular biology identification of the isolates was performed in both cases. The literature is reviewed regarding all similar cases.
