On the ultrastructure of Trichomonas vaginalis: cytoskeleton, endocytosis and hydrogenosomes

This paper is focused on the study of the ultrastructure of Trichomonas vaginalis in liquid cultures. Its cytoskeleton, the morphology of its hydrogenosomes, and endocytosis phenomena have been observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). For the present...
