Taxonomy of protozoa

1. Taxonomy of Protozoa Prepared by: NOE P. MENDEZ CENTRAL MINDANAO UNIVERSITY (CMU) [email protected]

2. Protozoa Unicellular Eukaryote Binary Fission Replication Motile

3. Taxonomy is the science of naming, describing and classifying organisms

4. Classification of Protozoa Protozoa as a subkingdom Contains 7 phyla Phylum Sarcomastigophora Phylum Labyrinthomorpha Phylum Apicomplexa Phylum Microspora Phylum Ascetospora Phylum Myxozoa Phylum Ciliophora

5. Phylum Sarcomastigophora Protists that have a single type of nucleus and possess flagella Both Sexual and Asexual reproduction Subphylum Mastigophora and Sarcodina Mastigophora Sarcodina

6. Subphylum Mastigophora Contains both phytoflagellates and zooflagellates Class: Zoomastigophora Examples: Trypanosoma , Giardia, Trichomonas , Leishmania , Trichonympha

7. Trypanosoma brucei Giardia lamblia Trichomonas vaginalis

8. Subphylum Sarcodina Contains amoeboid protist Found in both fresh and salt water Class Rhizopoda Examples: Amoeba, Elphidium , Coccodiscus , Naegleria , Entamoeba

9. Amoeba Entamoeba histolytica Naegleria floweri

10. Phylum Labyrinthomorpha Consist of protists that h ave spindled-shaped Example: Labyrinthula Labyrinthula

11. Phylum Apicomplexa Often called sporozoans Spore-forming stage in their life cyle Lack special locomotory organelles Examples: Plasmodium, Taxoplasma , Eimeria , Cryptosporidium

12. Plasmodium falciparum Taxoplasma gondii Cryptosporidium parvum

13. Phylum Microspora Obligatory intracellular parasites lacking mitochondria Examples: Nosema Nosema apis

14. Phylum Ascetospora Small phylum Consists exclusively of parasitic protist Example: Haplosporidium Haplosporidium costale

15. Phylum Myxozoa All parasitic Found in freshwater and marine Example: Myxosoma Myxosoma cerebralis

16. Phylum Ciliophora Largest phyla 8,000 species Cilia as locomotory organelles Example: Didinium , stentor , Vorticella, T etrahymena , Paramecium, T okophrya , E ntodinium , N yctotherus , B alantidium , I chthyophthirius

17. Paramecium Stentor Entodinium Nyctotherus ovalis

18. Balantidium coli Ichthyophthirius multifiliis
