Trichomonas vaginalis (15-20 µm) on vaginal smear (phase contrast examination)

France, CHU Angers Parasitologie-Mycologie

Undulating membrane, 4 anterior flagella and the posterior part of axostyle are quite apparent. Undulating membrane stops the 3d posterior part of trophozoite, unlike that of Trichomonas intestinalis (differential diagnosis feature).
