Represented by :- FANIT YADAV

2. Pathogenic
protozoa
Intestinal urogenital
Blood and
tissue

3. Intestinal

4. • A. amebas - Move by extending cytoplasmic projections.
• B. flagellates -Move by rotating whip-like flagella.
• C. ciliates- Move by synchronous beating of hair-like cilia.
• D. sporozoa- Generally have nonmotile adult forms.

5. INTESTINAL PROTOZOAL
INFECTIONS
• A. Amebic dysentery (Entamoeba histolytica)
• B. Giardiasis (Giardia lamblia)
• C. Cryptosporidiosis (Cryptosporidium species)
• D. Balantidiasis (Balantidium coli )

7. Urogenitals

8. Trichomonas vaginalis
(Flagellate)
• Trichomoniasis is the most common protozoal urogenital tract infection
of humans.
• Pear-shaped flagellates.
• No cyst form in the life cycle of Trichomonas.
• Higher then normal ph favours disease.

9. • In females - it causes inflammation of the mucosal tissue of the
vagina, vulva, and cervix, accompanied by a copious, yellowish,
malodorous discharge.
• In males (less commonly) - it infects the male urethra, prostate, and
seminal vesicles, producing a white discharge.
• Diagnosis is made by detection of motile trophozoites in vaginal or
urethral secretions.

10. BLOOD AND
TISSUE
PROTOZOAL
INFECTIONS

11. A. Malaria (Plasmodium falciparum
and other species)

13. B. Toxoplasmosis (Toxoplasma
gondii)
• Toxoplasma gondii is an intracellular sporozoan
• Infects all vertebrate species
• Definitive host is the cat.
• Humans can become infected by the accidental ingestion of oocysts
present in cat feces, by eating raw or undercooked meat, congenitally
from an infected mother, or from a blood transfusion.

14. • C. Trypanosomiasis (various trypanosome species)
• D. Leishmaniasis (various Leishmania species)
• F. Babesiosis (Babesia microti )
