Brevibacterium casei isolated as a cause of relapsing peritonitis

We report a case of relapsing peritonitis in a 33-year-old woman on automated peritoneal dialysis. End-stage renal disease was secondary to systemic lupus erythematosus complicated with lupus nephritis. The organism isolated was Brevibacterium casei that was not readily identified, delaying appropriate management with an extended antibiotic course. Definite management of B casei peritonitis was peritoneal dialysis catheter removal. Copyright 2014 BMJ Publishing Group. All rights reserved.
