A relationship between 2 species
when any 2 organisms live in close

in or on the body of another.
What is a symbiotic
relationship?
These parasites live within the
body and tissues of host (Ex.
Plasmodium inside RBC)
What are endoparasites?
This group of parasites includes
flatworms; such as flukes and
tapeworms.
What is Platyhelminthes?
A type of commensalism where
one organism attaches to another
and “hitches a ride”
What is phoresy?
This is characterized by a constant
number of pathogens.
What is infestation?
This genera goes through the
epimastigote, promastigote, and
amastigote stages during its life
cycle.
What is Leishmania?
The site where Leishmania
amastigotes replicate.
What is a macrophage?
This parasite is transmitted by a
stercorarian vector.
What is Trypanosoma cruzi?
The site where Tyrpanosoma
brucei replicate.
What is the Tsetse fly gut?
This parasite causes Kala Azar,
which is the systemic infection of
reticulo-entothelial cells
throughout multiple internal
organs and the blood.
What is Leishmania donovani?
Glossina is the vector of this
parasite.
What is T. brucei?
The pinworm is in a
commensalistic relationship with
this parasite.

Phlebotomidae is the vector of this
parasite.
What is Leishmania?
Triatoma gerstaickeri is the vector
of this parasite.
What is T. cruzi?
A monogamous insect that gives
live birth.
What is Glossina?
A cresent shaped structure that is
found in Opilina sp.
What is a falx?
A DNA containing compartment
located with the single
mitochondrion and associated
with the flagella base.
What is a kinetoplast?
The ability of a parasite to change
the proteins it presents to the
host’s immune system.
What is Antigenic Variation?
A flexible structure found in
Trichomonads that commences at
the nucleus and bisects the
parasite.
What is an axostyle?
A structure that is present in
anaerobic and aero tolerant
organisms that is involved in
carbohydrate metabolism and
drug therapy.
What are hydrogenosomes?
A bulls eye rash that appears in a
person with Chagas disease.
What is a chagoma?
A local inflammation caused by
Trypanosoma brucei.
What is a chancre?
This amoeba is found in the
mouth.

An enlargement of the lymphtic
glands (especially the posterior
triangle of the neck).
