Neisseria sicca, previously classified as a ''nonpathogenic'' organism
, has now been recognized as a cause of many infections, including end
ocarditis and meningitis. However, it has not been reported as a cause
of peritonitis. We present a case of documented N. sicca peritonitis
immediately following an episode of Staphylococcus aureus peritonitis
in a pediatric chronic peritoneal dialysis (CPD) patient. N. sicca sho
uld be considered as a possible pathogen in CPD-associated peritonitis
.
