pleomorphic - different sizes and may be seen dividing
slender or stumpy
nucleus stains darkly
kinetoplast at posterior end
flagellum at anterior end
undulating membrane
Trypanosoma cruzi - chagas disease
very little size variation
flagellum at anterior
large kinetoplast at posterior
c formation
nucleus stains darkly
undulating membrane
amastigote of T. cruzi
muscle fibres of smooth muscle forces apart
amastigotes in pseudocysts
no dividing forms in peripheral blood as divide in smooth muscle
nucleus stains darkly
oval shape
Leishmaniasis - Leishmania spp - structurally similar amastigotes
nucelus and rod shaped kinetoplast stain dark purple
closely associated due to rupture of the cell
