Two possibly related cases ofMycobacterium fortuitum peritonitis associated with continuous ambulatory peritoneal dialysis

This paper describes two possibly related cases of hospital-acquiredMycobacterium fortuitum peritonitis associated with continuous ambulatory peritoneal dialysis (CAPD). To our knowledge these are the first reported cases of CAPD peritonitis with possible cross-contamination by such a microorganism. Investigations for mycobacteria should be performed in all cases of culture-negative peritonitis, especially those which do not respond to the usual antimicrobial therapy.
