Correct answer: C — Trichomonas vaginalis

A strawberry cervix (punctate haemorrhages on the cervix visible on speculum — pathognomonic but present in only ~2% of cases) with motile flagellated protozoa on wet mount is diagnostic of Trichomonas vaginalis. Treatment is oral Metronidazole — either 400 mg BD for 5–7 days or 2 g single dose. Partners must be treated simultaneously. Test of cure is recommended at 3 weeks. Patients should avoid alcohol during and for 48 hours after Metronidazole (disulfiram-like reaction). T. vaginalis increases HIV transmission risk.
