Haemoflagellates 

Live in blood and tissue of human, some other vertebrates and in the gut of insect vectors.
Two hosts are necessary for the completion of their life cycle :


Definitive
Intermediate


Haemoflogellates occur in various morphological forms :


Amastigote
Promastigote
Epimastiogte
Trypomastigote


These morphological forms are differentiated on the basis of


Size and shape of the cell
Position of the blepharoplast in relation with nucleus.
Presence of an external flagellum
Presence of an undulating membrane 

​Hemophlagellates are
