5. kingdom : Protista (Protozoa)
Only a few of the many tens of thousands of protozoa species are pathogenic for humans
(I) Pathogenic protozoa:
1- Intestinal:
Entamoeba histolytica (Ameba).
Giardia lamblia (Flagellate).
Cryptosporidium parvum (Sporozoan).
2- Urogenital:
 Trichomonas vaginalis.
3- Blood and tissues:
 Plasmodium species (Sporozoan).
 Toxoplasma gondii (Sporozoan).
 Trypanosoma species (Flagellate).
 Leishmania species (Flagellate).

6. The subkingdom protozoa contains the following phyla:
1- Phylum: Sarcomastigophora: (a) Subphylum: Sarcodina e.g. Amoeba
(b)Subphylum: Mastigophora e.g. Trypansoma
 Digestive and genital tracts
 Blood and tissues.
2- Phylum: Ciliophora (Ciliates): Balantidium coli Intestinal parasite of man.
3- Phylum: Apicomplexa: Class: Sporozoa: Asexual and sexual generations (All are parasitic). (e.g. Malaria).

7. Moving:  Amebas : Move by extending cytoplasmic projections.
 Flagellates : Move by rotating whip – like flagella.
 Ciliates : Move by synchronous beating of hair – like cilia.
 Sporozoa : Generally have non-motile adult forms.

12. Intestinal Infections
There are three principal protozoal intestinal parasites: the ameba Entamoba histolytica, the flagellate, Giardia lamblia and several varieties of sporozoa, Cryptosporidium parvum. Each causes a dysentry which although similar, differs in the site of infection, the severity and secondary consequences.
