Antibodies inhibit parasite replication and also induce parasite death via the classical pathway of complement. [citation needed] Infection with Giardia typically results in a strong antibody response against the parasite. While IgG is made in significant amounts, IgA is believed to be more important in parasite control.
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.

The parasite is responsible for the disease known as river blindness in Africa. Sample was chemically fixed and critical point dried, then observed using conventional scanning electron microscopy. Magnified 100×. Parasitology is the study of parasites, their hosts, and the relationship between them.
“When you’re bitten, the tick transfers that molecule, galactose-α-1,3-galactose, to the body,” explains William Schaffner, M.D., an infectious disease specialist and professor at the ...
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 ...
