Streptococcus salivarius peritonitis in an infant receiving chronic peritoneal dialysis

摘要

Peritonitis is the most common infectious complication of chronic peritoneal dialysis in children and the most common reason for hospitalization. Although the most common organisms responsible for peritonitis are gram-positive bacteria, peritonitis has not previously been reported secondary to Streptococcus salivarius, one of the 26 species in the Streptococcus viridians group. We describe a 4-month-old male who developed S. salivarius peritonitis while receiving automated peritoneal dialysis and who was successfully treated with a 14-day course of intraperitoneal vancomycin. Subtyping episodes of S. viridans-related infection is essential for the identification of S. salivarius.
