Unusual Cause of Peritonitis in Peritoneal Dialysis Patient Related to Streptococcus salivarius

Peritonitis remains the most common serious complication associated with peritoneal dialysis (PD). The Gram-positive peritonitis with Staphylococcus aureus and coagulase-negative Staphylococcus are the most frequent causes, whereas Gram-positive and Gram-negative species remain less frequent. We report an uncommon case of PD-related peritonitis due to Streptococcus salivarius, known as nonpathogen Gram-positive bacteria of oral flora.
