A

amastigote –> promastigote –> epimastigote –> trypomastigote

17
Q

Where do amastigotes live?

A

inside host’s muscle cell

18
Q

At what stage does the undulating membrane form?

A

epimastigote

19
Q

What characterizes the different morphological forms of trypanosoma?

A
  • flagellum

- kinetoplast

20
Q

T. lewisi flagellum and kinetoplast

A
  • little flagellum free of undulating membrane

- kinetoplast is posterior, but not terminal

21
Q

T. cruzi flagellum and kinetoplast

A
  • flagellum emerges from kinetoplast to opposite end

- kinetoplast is at the end

22
Q

T. gambiense flagellum and kinetoplast

A
  • flagellum present

- kinetoplast is at one end

23
Q

T. carassii flagellum and kinetoplast

A
  • flagellum is anterior after it passes through kinetoplast and body
  • kinetoplast is at posterior end
24
Q

T. rotatorium flagellum and kinetoplast

A
  • little flagellum free of undulating membrane
