5. 5 kingdom : Protista (Protozoa) Only a few of the many tens of thousands of protozoa species are pathogenic for humans 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). (I) Pathogenic protozoa:

6.  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.   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. 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.
