What are the stages of Giardia lamblia?
Giardia has one of the simplest life cycles of all human parasites. The life cycle is composed of 2 stages: (1) the trophozoite (see the first image below), which exists freely in the human small intestine; and (2) the cyst, which is passed into the environment. No intermediate hosts are required.
What is the feeding stage of Giardia lamblia?
Life Cycle When Giardia cysts are swallowed, they pass through the mouth, esophagus, and stomach into the small intestine where each cyst releases two trophozoites through a process called excystation. The Giardia trophozoites then feed off and absorb nutrients from the infected person.
What is the diagnostic stage of Giardia lamblia?
Laboratory Diagnosis Giardiasis is diagnosed by the identification of cysts or trophozoites in the feces, using direct mounts as well as concentration procedures. Cysts are typically seen in wet mount preparations, while trophozoites are seen in permanent mounts (i.e. trichrome).
