Part I Medical Parasitology Prof Dr Ahmed Ali Mohammed II The flagellates The flagellates are a group of protozoa distinguished by having one to several threadlike extensions from the ectoplasm in their trophozoite stage called flagella single flagellum The flagellate protozoa that parasitize man primarily divided to.
