The aim of this study was to observe morphological changes of Trichomonas vaginalis after contact with human vaginal epithelial cells, by scanning electron microscope. The vaginal epithelial cells (VEC) (menstrual, days $5\sim10$) from normal women were mixed with T. vaginalis (VEC/trichomonads ratio of 1 : 10), and incubated for 30 min. The parasitic body was changed to a more elongated shape with pseudopodia or was flattened to ameboid transformation showing highly adherence to VEC.
