A case of asymptomatic urinary tract infection with Neisseria subflava biovar perflava in a 10-year-old male patient with congenital structural abnormalities of the urinary bladder is presented. The organism was recovered from three catheter urine specimens collected over a seven-month period. A brief review of the role of saprophytic Neisseria species in infectious processes is presented and the likely source of this unusual urinary tract isolate is discussed.
