Urinary tract infection by Trichomonas vaginalis in a newborn baby.

Abstract
A female infant of approximately 28 weeks'' gestation was noted to have abdominal distension and readily palpable kidneys on the 19th day of life. T. vaginalis was present in the urine and was associated with significant pyuria. These findings persisted until the 64th day when oral treatment with metronidazole 50 mg. t.d.s. [3 times daily] for 7 days was started, and proved rapidly effective in eradicating the parasite and the pyuria. The infant was normal at a follow-up examination at 4 months.
