Which organism is the causative agent of giardiasis?

Giardiasis is caused by Giardia lamblia, a flagellated protozoan parasite that lives in the small intestine. People ingest cysts from contaminated water or food, which then release trophozoites that cause symptoms such as bloating, cramps, and greasy, foul-smelling diarrhea due to malabsorption. This organism is distinct from Entamoeba histolytica (which causes amebic dysentery), Vibrio cholerae (the bacterium that causes cholera), and Cryptosporidium parvum (which causes cryptosporidiosis). So, Giardia lamblia is the causative agent of giardiasis.
