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.
Giardia (/ dʒ iː ˈ ɑːr d i ə / or / ˈ dʒ ɑːr d i ə /) is a genus of anaerobic flagellated protozoan parasites of the phylum Metamonada that colonise and reproduce in the small intestines of several vertebrates, causing the disease giardiasis.
Advocates claim that antigen tests are less expensive and can be scaled up more rapidly than PCR tests. [8] Antigen tests are available for a variety of conditions, including streptococcus, [15] influenza, giardia, [16] Ebola and Helicobacter pylori. [17] Antigens can be detected via blood, urine or stool. [citation needed]
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 ...

Cryptosporidium, sometimes called crypto, is an apicomplexan genus of alveolates which are parasites that can cause a respiratory and gastrointestinal illness (cryptosporidiosis) that primarily involves watery diarrhea (intestinal cryptosporidiosis), sometimes with a persistent cough (respiratory cryptosporidiosis).
Importance of T helper cells in an immune response: T helper cells recognize antigens from antigen-presenting cells (APCs) and then release cytokines and activate other immune cells. Parasitic worms influence what kinds of T helper cells are activated.
