Mycobacterium immunogenum is a member of the rapidly growing non-tuberculous mycobacteria and is a relatively new species identified within this group. An 81-year-old immune-competent male was diagnosed with M. immunogenum infection of his peritoneal dialysis catheter exit site and surrounding soft tissue. To our knowledge, this is the first reported case of M. immunogenum infection of a peritoneal catheter. Treatment included catheter removal, local surgical debridement, and combination antimicrobial therapy. Herein, we review literature describing antibiotic management of M. immunogenum, an organism for which optimal therapy is not defined.
