CWBCs > 10 per high power field

DMotile trichomonads

3

A 28-year-old woman presents with a malodorous vaginal discharge and itchiness that have lasted for 15 days. She reports that the smell of the discharge is worse after intercourse and is accompanied by a whitish-gray fluid. She has no significant past medical or gynecological history.

BVaginal fluid pH < 4.5, lactobacilli predominance on the microscopic examination of the vaginal secretions, which are scant and clear

CVaginal fluid pH > 5.0, motile flagellated pyriform protozoa seen on the microscopic examination of the vaginal secretions
