Acute Peritonitis Caused by Staphylococcus capitis in a Peritoneal Dialysis Patient

Abstract

Acute peritonitis remains the most common complication of peritoneal dialysis (PD), with coagulase-negative staphylococci (CoNS) reported to account for more than 25% of peritonitis episodes ( 1 ). Staphylococcus capitis is a gram-positive, catalase-positive CoNS that was originally identified as a commensal on the skin of the human scalp ( 2 ). Advancement of microbiological technologies for bacterial identification enables diagnosis of previously unknown causes of acute peritonitis. This is the first reported case of acute peritonitis in a PD patient caused by S. capitis.
