    Study Notes

    Flagellates and their Characteristics

    • Trichomonas is associated with the urogenital tract.
    • The ventral disk is the primary organelle of attachment in Giardia lamblia.

    Giardia lamblia Characteristics

    • Excystation in Giardia lamblia can occur at a pH of 2.
    • Giardia lectin, also known as taglin, has a molecular weight of approximately 30-32 kDa.
    • Trichomonas is associated with oral infections.

    Giardia lamblia Attachment and Activation

    • Giardia lamblia can attach intimately to the intestinal epithelium.
    • The prolectin found within the trophozoite of Giardia lamblia can be activated by phospholipids.
    • The lectin taglin is distributed throughout the parasite surface in Giardia lamblia.

    Excystation in Giardia lamblia

    • Excystation in Giardia lamblia occurs in the small intestine.
