Neisseria mucosa is part of the normal nasopharyngeal flora and rarely pathogenic in humans. Reports of serious infections associated with this pathogen are very unusual. A 17-year-old boy with end-stage renal disease due to IgA nephropathy presented with acute, spontaneous, symptomatic peritoneal, dialysis-associated peritonitis without reported break in sterility or PD catheter exit site infection. β-lactamase-negative N. mucosa was isolated from the dialysate effluent. Intraperitoneal antibiotic treatment with cephalothin/gentamicin for 5 days and subsequent ceftriaxone led to complete resolution of the infection. This case demonstrates that "non- pathogenic" Neisseria species can cause clinically severe peritonitis with high intraperitoneal neutrophil counts, elevated C-reactive protein levels in the peritoneal effluent (in the presented case, 27,600/μl and 3.6 mg/l, respectively) and impaired peritoneal membrane transport function. To our knowledge, this is the first case of N. mucosa peritonitis complicating chronic peritoneal dialysis in an adolescent patient.
