• 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.

• D. Balantidiasis (Balantidium coli )
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.

9. • In females - it causes inflammation of the mucosal tissue of the
vagina, vulva, and cervix, accompanied by a copious, yellowish,
malodorous discharge.

• Diagnosis is made by detection of motile trophozoites in vaginal or
urethral secretions.

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)
