GIARDIASIS FACT SHEET Overview Giardiasis is a protozoan infection which causes acute, diarrheal illness. Giardia, a flagellate protozoan, is a microscopic parasite that feeds off the human or animal host once ingested. This microscopic parasite lives in the intestines of the host and can be passed in the feces Giardiasis Overview 1, 2, 3 Giardiasis is the most common intestinal parasitic infection of humans. Giardia intestinalis (G. intestinali) formerly Giardia lamblia or Giardia duodenalis is a flagellate protozoan that exists as a trophozoite and in cyst form; the infective form is the cyst. Once a person or animal (e.g., cats giardiasis? Giardia are found in soil, food, water, or surfaces that have been contaminated with the feces from infected humans or animals. Infection occurs after accidentally ingesting the parasite. How does giardiasis affect my animal? Most animals with giardiasis show no signs of disease. Diarrhea can occur, most commonly in younger animals The diagnosis of giardiasis is commonly made by the identification of trophozoites or cysts in stool specimens. The organism can either be directly visualized on routine ova and parasite (O&P) testing or visualized using a direct fluorescent antibody test. Enzyme immunoassays (EIA) are also commonly used to diagnose giardiasis. Man

Giardia Classification, Cell Biology, Life Cycle and Microscopy Overview. Giardia is a genus consisting of a number of flagellated species with similar morphological characteristics. Members of this genus can be found in various environments (water, soil etc) and are responsible for giardiasis (a diarrheal illness) in both human beings and other vertebrates Giardia lamblia is recognized as a one of the most prevalent protozoa and a frequent cause of gastroenteritis, but there is also increasing evidence of extra-intestinal manifestations and long-term complications after its clearance. Additionally, giardiasis has also been associated with a reduction in zinc absorption and other essential minerals

Giardia lamblia, a flagellate waterborne protozoan parasite, is a common cause of gastrointestinal disease in industrialized and unindustrialized countries ().Most information on risk factors for giardiasis has come from investigation of outbreaks. Water is the most frequently identified route of transmission (1,2), through drinking contaminated tap water (3,4) or recreational exposure in. Giardiasis affects the body's ability to absorb fats from the diet, so the diarrhea contains unabsorbed fats. That means that the diarrhea floats, is shiny, and smells very bad.
