Case #486 – February, 2019

A 10-year-old female patient from Argentina was taken to the hospital by her parent with complaints of “not feeling well.” A urine sample was collected and examined as part of the routine checkup. Microscopic examination of the urine sediment using the 40x objective lens revealed the following: 0-1 WBC and 0-2 RBC per field and a motile organism shown in the video that was sent to the DPDx team for identification. Still images of the organism were made by capturing screenshots at different points of the video (Figures AC). What is your diagnosis? Based on what criteria?

This case and video was kindly provided by the Hospital Clinicas de Cordoba/Universidad de Cordoba, Argentina.
