Order of Mastigophora.

General Information

Apart from the genera Histomonas (one free flagellum) and Dientamoeba (no flagellum), the trichomonadids listed in Table 1 are provided at their apical pole with 4, 5, or 6 free flagella and an additional recurrent flagellum (Figs. 1, 2) which runs along a surface wave giving rise to the aspect of an undulating membrane (Fig. 1, RF). Further characteristics of trichomonads are the axostyle, pelta, costa, and parabasal bodies, which serve as cytoskeleton (Figs. 1, 2).
