Vírus
Virus, the enemy public number 1 He doesn''t measure more than 30 millionth of mm. Cause influenza, measles, paralysis,
variola, AIDS and etc. he/she doesn''t feed breathes, nor it produces thing some, but it is capable to multiply. For that, he/she takes advantage of the mechanisms of the cells where he/she stays, later it sacrifices them. They are known about 1000 virus species, responsible for 60% of the diseases in animals and plants. To each step, he/she is discovered the virus presence where was not suspected. One was found in the spinal liquid of 17 of the schizophrenic 50 examined. The antibodies are a threat of the organism against strange agents, they are as operated by remote control missiles. Viral diseases in general stayed a mystery until the invention of the electronic microscope in the decade of 1940. The equipment allows to see the virus, that means poison in Latin and that it was isolated and photographed for the first time in the decade of 1950. Many antibodies live and they die ingloriamente without to find the antigen for which you/they were done and to lock with him a life battle or death. The vaccine is always composed of inactive virus or lessened, whose function is to call the attention of the antibody, that wakened up fight with the false virus. When unaware, the cell receives the virus in a friendly way, without noticing that this is a stranger full of bad intentions. The guest betrays the host, he/she runs for the nucleus, a type of brain of the cell and it takes him/her the commands. The cell starts to manufacture compulsivamente more and more virus, until that of so flood, she bursts, more virus, that invade neighboring cells proliferating. We that you/they possess RNA retrovírus are called, where a located enzyme inside of an involucre of the virus he/she has to transform RNA in DNA, because that is the only acid capable to enter in the nucleus. Drugs like AZT look for to hinder the life of the retrovírus of AIDS, eliminating such enzyme. The organism, when feeling the presence finds strange, he/she sends white globules of the blood, called macrófagos that swallow the infected cell. The cells existent T in the blood begin to manufacture the antibodies under measure that you/they kill or they neutralize the viruses. The production of these delay from 3 to 7 days, the virus of AIDS attacks the cells exactly T. That happening, he/she opens up space for a series of infections opportunists. They would not appear case the cells T worked usually. The virus of the influenza is one of the more mutants, only losing for the one of AIDS, where each generation doesn''t at least last one month
