FIG. 9.16. A: Trichomonad in the vaginal discharge of a 17-year-old patient with gonococcal pelvic inflammatory disease. The flagellated protozoan is elliptical and somewhat larger than the adjacent polymorphonuclear leukocytes (2253 magnification). B: After suspension in saline solution for microscopy, trichomonads gradually become swollen and immobile. This balloon-shaped trichomonad is barely recognizable (2253 magnification).
