Abstract
Aerococcus urinae (A. urinae) infection, primarily observed in elderly patients, is a rare yet emerging occurrence in the pediatric population. Advances in laboratory techniques have facilitated the increased identification of these bacteria in human infections. There have been only a few recent cases reported among children. The scarcity of literature on the clinical presentation and management of such infections in children presents a challenge for pediatricians. Here, we present the case of a 15-month-old male child with Down syndrome who presented with malodorous urine but lacked other typical symptoms of urinary tract infection. Upon investigation, urine analysis revealed pyuria, and urine culture confirmed A. urinae infection. The patient also exhibited underlying bilateral mild to moderate hydronephrosis. Successful treatment was achieved with a three-day course of amoxicillin, leading to symptom resolution. This case underscores the significance of promptly identifying A. urinae infection in pediatric patients presenting with malodorous urine, as a timely intervention with a short course of treatment may avert more severe and invasive infections.
