Giardia

 [je-ahr´de-ah]
a genus of flagellate protozoa parasitic in the intestines of humans and other animals, which may cause protracted, intermittent diarrhea with symptoms suggesting malabsorption. G. lamb´lia (called also G. intestina´lis) causes giardiasis.

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.
[Alfred Giard, Fr. biologist, 1846-1908]

Giardia

/Gi·ar·dia/ (je-ahr´de-ah) a genus of flagellate protozoa parasitic in the intestinal tract of humans and other animals, which may cause giardiasis; G. lam´blia (G. intestina´lis) is the species found in humans.

giardia

(jē-är′dē-ə, jär′-)
n.
Any of various flagellated, usually nonpathogenic protozoa of the genus Giardia that may be parasitic in the intestines of vertebrates including humans and most domestic animals.

Giardia

[jē·är′dē·ə]
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.

The presence of Giardia in the gut causes the intestinal epithelial barrier to lose proper function, although scientists are still trying to figure out the precise biochemical mechanisms responsible for this.
El diagnostico de la presencia de Giardia spp se realiza por la observacion directa de trofozoitos y quistes en heces por el metodo del frotis directo [12, 39] y el metodo de flotacion con sulfato de zinc [39], en el cual se evidencia la presencia de quistes, la cuantificacion se realiza por conteo de formas quisticas y trofozoitos en una escala cualitativa dada en cruces [6, 12, 35].
