Parasitology Ch. 10 and 11
1. What type of organism are protozoans?: They are unicellular
2. What are the three most important phyla of protozoans?: Sacromastigophora, Cilio-
phora, Apicomlexa
3. Contains flagelates and amoebae?: Sarcomastigophora
4. Contains the ciliates?: Ciliophora
5. Contains the coccidia, malarial organisms, and piroplasms: Apicomplexa
6. What does Trophozoite form mean?: the moving or motile form/stage (flagellates)
7. These protozoans possess at least one flagellum in their trophozoite form.
Trophozoite means motile.: Mastigophora (flagellatetes)
8. Some important genera of Mastigophora are?: Leishmania, Trypanosoma, Trichomonas,
Histomonas, Giardia
,9. What do Sarcodina (amoebae) portozoans move by?: pseudopodia
10. What is the main characteristic of Sarcodina protozoans?: They are poorly defined, or
blob-like in shape
11. What are the 2 forms of Scarcodina (amoebae)?: Trophozoite form (motile) and Resistant
cyst form (can survive in adverse conditions in the external environment)
12. Protozoan Ciliphora move by what?: cilia
13. Ciliphora (ciliates) also have a Trophozoite form and a resistant cyst form.
True/False?: True
14. What is unique about Ciliophora protozoans?: They have 2 types of nuclei: the macronucleus
and the micronucleus
15. What characteristic of Apicomplexa protozoans allows it to move?: organelles that
are not visible and are internal
16. What protozoans are the most divers and complicated and found in almost
, every animal phylum and are often comma or banana shaped?: Apicomplexa (Apicom-
plexans)
17. Eimeria, Cystoisospora, Toxoplasma, Sarcocystis, Cryptosporidium, Plas-
modium, Haemoproteus, Leukocytozoon, Babesisa, Therileria, Cytauxzoon,
Hepatozoon are all imporant genera of?: Apicomplexans
