Giardia(jē-ar'dē-ă), Avoid the misspelling/mispronunciation Girardia.
A genus of parasitic flagellates that parasitize the small intestine of many mammals, including most domestic animals and humans; for example, Giardia bovis in cattle, Giardia canis in dogs, and Giardia cati in cats. Many species have been described, but current research suggests that these should be reduced to only two or three.

Etymology: Alfred Giard, French biologist, 1846-1908
a common genus of flagellate protozoans and a major cause of nonbacterial diarrhea in North America and of intestinal disease globally. Many species of Giardia normally inhabit the digestive tract and cause inflammation in association with other factors that produce rapid proliferation of the organism. See also giardiasis.
A genus of flagellates that parasitize the small intestine of human beings, domestic and wild mammals, and birds.
A genus of flagellates that parasitizes the small intestine of human beings, domestic and wild mammals, and birds.
a genus of flagellate protozoa parasitic in the intestines of most animals. They are capable of causing protracted, intermittent diarrhea suggestive of malabsorption, sometimes dysentery, but many infections may be non-symptomatic. Includes G. bovis (cattle), G. canis (dogs), G. caprae (goats), G. cati or G. felis (cats), G. caviae (guinea pigs), G. chinchillae (chinchillas), G. duodenalis (rabbits), G. equi (horses), G. felis (cats), G. intestinalis (G. lamblia; found in humans, pigs, budgerigars, monkeys), G. muris (mice, rats).
