Amoeba parasites Definition: Amoeba parasites is a microscopic parasite called Entamoeba histolytica (E. histolytica) which causes internal inflammation. It is a single-celled organism and that is how the illness got its name – amebiasis. When the cysts survive the acidic stomach it transforms back to trophozoites in the small intestines then migrates to the large intestines where they multiply and live. Obtaining the parasite: Amoeba parasites are transmitted by eating and drinking something

Parasites and Humans: Why Can’t We All Just Get Along? Introduction The definition of a parasite is: “an organism that lives on or in an organism of another species‚ known as the host‚ from the body of which it obtains nutriment.” (Dictionary.com‚2012) There are several kinds of parasitic relationships in the world. Mutualism is one of them. This occurs when each member of the association benefits the other. Can humans and parasites have a mutualistic relationship in medicine?

Parasites: Uncovering the Role of the Parasite Host Relationship According to the CDC around seventeen percent of Americans are infected with only one type of parasite. This figure did not take into account all the species of parasites‚ nor the percentage of the undeveloped world infected‚ and when taken into consideration the figures are staggering. Parasites are organisms that make their living by residing attached to or within another organism. They use the organism for food‚ shelter‚ and

About seventy-five percent of cases do not have any symptoms‚ even though the bacteria are present in their feces for 7-14 days post infection and are shed back into the environment‚ potentially infecting other people. Approximately 5% of infected persons will have severe disease characterized

Parasites have evolved in a very specific and selective way throughout generations. Specific parasites have specific factors that influence their site selection process and that work in favor for the parasites. One important component that influences the parasite to become site specific is being host specific‚ which in turn affects the ability of extracting resources. The more efficient it is in extracting resources the better the chance of reproducing‚ which then increases the fitness of the parasite
