Explanation / Answer
1. It is best done by antigen testing of the stool. It can also be done by examining the stool under the microscope for cysts or trophozoites.
2. There are various drugs available like furazolidone and metronidazole.
3.By using clean water for watering the crops. Fresh fruits and vegetables come in contact with water during various stages of the production process. Contaminated water that is used during crop production, harvesting, and processing can lead to health issues.
4. Giardiasis is transmitted with infected water with the faeces of the infected individual. If you seem to drink or consume that infected water then you will be at the risk of getting giardiasis. It can be prevented by
1. Giardia cysts are the infective stage of G. intestinalis. As few as 10 cysts can cause infection.
2. These cysts are ingested by consuming contaminated food or water, or fecal-orally. They can survive outside the body for several months, and are also relatively resistant to chlorination, UV exposure and freezing.
3. When cysts are ingested, the low pH of the stomach acid produces excystation, in which the activated flagella breaks through the cyst wall. This occurs in the small intestine, specifically the duodenum.Excystation releases trophozoites, with each cyst producing two trophozoites.
4. Within the small intestine, the trophozoites reproduce asexually (longitudinal binary fission) and either float free or are attached to the mucosa of the lumen.
5. Some trophozoites then encyst in the small intestine. Encystation occurs most likely as a result of exposure to bile salts and fatty acids, and a more alkaline environment. Both cysts and trophozoites are then passed in the feces, and are infectious immediately or shortly afterward . Person-to-person transmission is possible. Animals can also be infected with Giardia, and beavers have been associated with giardia outbreaks, although not definitively.
6. When irrigation water supply mixes with the sewage or by leakage of sewage in the irrigation water supply.
