Peritoneal dialysis-associated peritonitis caused by .

Peritonitis remains a common and serious complication of peritoneal dialysis. Peritonitis caused by gram-positive organisms includes coagulase-negative staphylococci, spp and spp. We present a rare case of peritoneal dialysis-associated peritonitis, where persisting abdominal pain and worsening laboratory findings despite antibiotic therapy led to the identification of , requiring Tenckoff catheter removal and temporary transfer to haemodialysis. The available literature reports only few cases where peritonitis is caused by this agent, underlining the need to consider atypical microbial agents when heterogeneous clinical course is presented.
