1)
Trypanosome cruzi. High power
view of reduviid bug (vector).
2)
T. cruzi – trypomastigote,
infective stage.
3) T. cruzi – amastigote, intracellular multiplicative stage.
4)
T. cruzi in heart. Amastigotes form pseudocyst in muscle cells
(Myocardium).
5)
Close up view of T. cruzi
pseudocyst in the heart.
6)
(Same as 5)
7)
After T cruzi pseudocysts burst
open.
8)
Leishmania – (amastigote
stage) in macrofage. [Promastigotes
are
infective of humans]
9) Trophozoite (replication stage).
Endosome + food vacuoles seen.
10)
(same as 9)
11)
Metacyst (four nuclei – cysts have only one nuclei). Infective stage
2 cromatoidal bars seen.
12)
Cysts
– infective stage.
13)
Trophozoite
in stool.
14)
Cyst in stool.
15)
Two cysts.
16) Trophozoite.
