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 have
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, Tetrahymena,
Paramecium, Tokophrya,
Entodinium, Nyctotherus,
Balantidium, Ichthyophthirius

17. Paramecium Stentor
Entodinium Nyctotherus ovalis

18. Balantidium coli Ichthyophthirius
multifiliis
