Giardiasis is a parasitic disease caused by Giardia duodenalis (also known as G. lamblia and G. intestinalis). [3] Infected individuals who experience symptoms (about 10% have no symptoms) may have diarrhea, abdominal pain, and weight loss. [1]
Giardia duodenalis, also known as Giardia intestinalis and Giardia lamblia, is a flagellated parasitic protozoan microorganism of the genus Giardia that colonizes the small intestine, causing a diarrheal condition known as giardiasis. [1] [2] [3] The parasite attaches to the intestinal epithelium by a ventral disc (syn.
About 40 species have been described, but most of them are probably synonyms. [11] Currently, five to six morphologically distinct species are recognised. [12] Giardia duodenalis (=G. intestinalis, =G. lamblia) infect humans and other mammals, G. microti infects voles, G. muris is found in other mammals, G. ardeae and G. psittaci in birds, and G. agilis in amphibians.

Giardia lamblia, an infectious protozoan. Protozoan infections are parasitic diseases caused by organisms formerly classified in the kingdom Protozoa. These organisms are now classified in the supergroups Excavata, Amoebozoa, Harosa (SAR supergroup), and Archaeplastida. They are usually contracted by either an insect vector or by contact with ...
Giardia lamblia: lumen of the small intestine: stool worldwide? ingestion of water containing deer or beaver feces Isosporiasis: Isospora belli: epithelial cells of small intestines: stool worldwide – less common than Toxoplasma or Cryptosporidium: fecal oral route – ingestion of sporulated oocyst Leishmaniasis: Leishmania spp.
The common intestinal parasite Giardia duodenalis (synonyms Giardia lamblia, G. intestinalis) was once considered to be a descendant of a protist lineage that predated the emergence of meiosis and sex. However, researchers found G. duodenalis to have a core set of genes that function in meiosis and that are widely present among sexual ...

Giardia lamblia is most common, but Entamoeba histolytica, Cryptosporidium spp., and other species have also been implicated. [13] [34] As a group, these agents comprise about 10% of cases in children. [24] [34] Giardia occurs more commonly in the developing world, but this type of illness can occur nearly everywhere. [36]
