Parasite refers to a kind of biological, most of the time his life living in another kind of animal, called on the host, and at the same time, to be parasitic animal damage.Women Supra Shoes, For example, the virus, and made g times austenitic, bacteria and parasites permanent or long-term or temporarily live on the plants, animals and people of the body surface or the body for nutrition, survival, and damage to each other, this kind of a parasitic life of biological collectively referred to as parasites; Over the life of the parasitic many cells invertebrates and unicellular protoctist said the parasite. A mention parasites, people usually associate with them to a variety of diseases, actually parasites sometimes use opportunely. British researchers have recently use a kind of parasites in cattle life for the carrier, to the ox vaccinal can prevent related diseases of the vaccine.

British Edinburgh university researchers institutions such as a new phase in an online journal of the public library of science pathogenic volume "report, this can be used as a vaccine carrier parasite called" tiger's eansi ". It is a harmless parasites, the researchers of the gm, make it has the effect of vaccine with material and able to release in the body. Because it can be on the bull's blood in the long-term breeding, the "parasites vaccine" with a protective effect. air jordan shoes,According to introducing, this "parasites vaccine" can be used to prevent DuoZhong cow diseases, such as foot-and-mouth disease and cattle TB, etc. Researchers think that not only can be used to give parasites carrier cattle vaccines, after the improvement may also could be used to deliver drugs to cow body directly, some disease treatment. Leading the study Keith Matthews professor says, this new method in cattle disease prevention and control has great potential, the hope can so as to help control even destroy some common cow diseases.

Nature, along with the long evolution process, biological and the relationship between biological more complex shape. Two creatures who live together in the phenomenon, collectively referred to as "symbiosis. In symbiosis phenomena according to two of the interest relationship between organisms can be roughly hair for commensalism, mutualism, parasitism, etc. Parasitic is in certain conditions appear in the parasites and host a specific relationship between. The parasites travel to the host, the host to produce different damage; At the same time to host the parasite reaction is produced different degree of resistance to try to make it clear. The results in the parasites may lead to form and function of the change, the host that appear in pathology. supra shoes online,Parasites and the interaction between the host, is often comprehensively in the role of each other, through long-term evolution process, parasites and host of interaction between some of the characters are preserved, and to reflect on both sides of the population genetic material.
