Giardia
Giardia
Giardia (/dʒiːˈɑːrdiə/ jee-AR-dee-ə) is a genus of anaerobic flagellated protozoan parasites of the phylum Sarcomastigophora that colonize and reproduce in the small intestines of several vertebrates, causing giardiasis. The parasite attaches to the epithelium by a ventral adhesive disc or sucker, and reproduces via binary fission.
Etymology
The term "Giardia" is derived from the name of French biologist Alfred Mathieu Giard, who first described the organism in the late 19th century.
