Rothia Mucilaginosa Peritonitis Complicating Peritoneal Dialysis

For the 11% of dialysis patients worldwide who receive peritoneal dialysis (PD) to treat their end-stage kidney disease (ESKD), recent PD-associated peritonitis is estimated to contribute to 5-30% of reported mortality.1,2 These infections are most commonly caused by coagulase-negative Staphylococcus (32%), followed by culture-negative peritonitis (16%), and the timely identification and targeted treatment of peritonitis is critical to avoid complications such as PD catheter removal.3 Here, we present a case of atypical Rothia mucilaginosis peritonitis in a PD patient.
