This is a very common parasite in human especially in children and can cause a disease giardiasis. The trophozoite is pear shaped.

It has two nuclei between which lie 8 basal bodies giving rise to 8 flagellae by means of which the parasite can swim.

The cysts are discharged in faeces and infection occurs via faeces contaminated drinking water.
