Giardiasis is caused by the Giardia parasite, which is a tiny parasite. It has a direct life cycle and lives in the upper part of its host's small intestine. The trophozoites emerge from the cysts in the duodenum and attach to the small intestine mucosa after the host consumes cysts, which constitute the infective stage.
