bacteria‚ virus‚ or parasite. Giardia is protozoan and also flagellated. Flagellated means using appendages in a whip-like movement to propel. Giardia attaches to the host through the lining of the upper intestines. Once it attaches itself‚ it begins to feed and reproduce causing the giardiasis to commence. Giardia reproduces by dividing itself‚ which defines it as a trophozoite. This process of division is known as binary fission. Because Giardia reproduces asexually‚ a single parasite can result in

Food Borne Illness: Giardia When generally thinking of parasites and food-borne illnesses‚ we tend to think about the poorest and dirtiest places on Earth. In Reality‚ parasites can be found almost anywhere on this planet. One type of common food-borne illness is a giardia infection. This infection is in the intestine and caused by microscopic giardia parasites. If given the opportunity this vicious creature will infect anybody regardless of sex‚ age‚ living conditions‚ and body types. Surprisingly

Giardiasis is a parasite that affects the digestive system. As a parasite‚ it feeds off another organism in order to survive. While it is uncommon in the developed world‚ it can be found in every region of the United States and around the world. It is frequently seen in developing and poor countries where it can affect a number of people due to poor hygiene and unsanitary conditions. As a parasite that can so lethally attack people‚ it displays a plethora amount of signs and symptoms in a patient

The Amoeba called the Sarcodines and the Flagellates called the Mastigotes are sometimes linked into one group called the Sarcomastigotes because of similar features. The Ciliates are about as complicated as single cells can be. The Sporozoans tend to be tiny parasites‚ often living inside other cells‚ but are also pretty complicated.

Keith Foy McDowell Bio 101 04/09/2012 Amoeba The amoeba falls under the classification Euklaryota. It is part of the Protista kingdom which is made up of the simplest known eukaryotes. These organisms are single celled with a membrane surrounding the nucleus. The amoeba genus has over 290 million species. The amoeba cell is described as riged with extending pseudopods located at the anterior side of the cell. The pseudopods are used to move the cell around. It also has extensions
