There is no super virus can infect all life forms ?

Studies have shown that early in our ancestors, “Homo sapiens” period, human viruses that fight harmful microorganisms and it has kicked off, in this long process, humans paid a painful price, while also exposing step by step open the mystery virus.

Sci-fi movie “Resident Evil” in the T-virus and G-virus are very afraid of chemical and biological weapons, which were developed a new type of virus transmission between humans and animals, humans eventually lost control of the wanton destruction of the human world in the film , viruses, human history than the history of this ancient creature much longer, not so easy to be human manageable.

Studies have shown that early in our ancestors, “Homo sapiens” period, human viruses that fight harmful microorganisms and it has kicked off, in this long process, humans paid a painful price, while also exposing step by step open the mystery virus. Virus as the only one class does not have cellular structure beings, are parasites. For the choice of the host cell should not be picky, but in how to choose the natural host of this process, the virus but reveals the “personality.”

Although almost every individual viruses are branded with unique imprint of the family, such as the “head” is very small, the structure is extremely simple, have a strong variation capability, however, each family member has its own “flavor.” Some viruses like parasites in the same microbial bacteria cells, called bacteriophages; Some viruses are “vegetarian”, but why can not move freely to the erosion of plants such as tobacco mosaic virus, known as the plant virus; Some viruses even more preferred animal cells, parasitic on animals known animal viruses, such as smallpox virus, HIV, etc.

In other words, the genetic code of a virus, it has decided to attack specific cell types and species. Animal and plant viruses can not attack it sick. Furthermore, a plant virus can not infect all plants. Such as polyoma virus double-stranded DNA comprising a polyoma virus, can infect birds, rodents and primates, it is in terms of a particular virus has its own optimum range of hosts, a viral high efficiency of infection is usually only one or a certain type of host, the formation of proliferative infection, the infection efficiency of the host low distantly related, can not be formed proliferative infection.

Another example is the first virus of human knowledge – the tobacco mosaic virus (Tobacco mosaic virus, TMV). It is a specialized plant RNA viral infection. As a very wide host range of pathogens, monocots are now known for 22 families of 198 kinds of plants with parasitic. However, the tobacco mosaic virus infection in tobacco and other specialized Solanaceae.

Tobacco mosaic virus is mainly spread through juice can make the infected leaves mottled look defaced. Healthy leaf disease caused slight friction micro-wound, the virus can invade. After the invasion in the parenchyma cells multiply, infect the whole plant into the vascular tissue. The locusts Tobacco, tobacco budworm and other chewing insects can also be disseminated TMV virus. So, even if the tobacco fields of locusts, tobacco budworm carrying the virus, but the tobacco mosaic virus and can not make it as a plant virus infection. On the other hand, tobacco mosaic virus, but can not make it pathogenic parasitic within 198 kinds of plants, but only infect tobacco and other Solanaceae.

We should feel lucky and did not appear a super virus that can “size takes all” infected all other life forms. Like the scientific community does not develop a universal solvent, as, otherwise, we take what container to save it? This is not consistent with the laws of nature.

A large number of scientific investigations and experiments have confirmed that bats are the natural hosts a variety of viruses. In the past 40 years, were isolated from a variety of bats to about 40 kinds of viruses. There rabies virus and rabies-related virus, Hendra virus, Menem high-virus, etc., and although no further confirmed.

But some researchers suspect that, at present, the spread of the Ebola virus in Africa’s natural host is the bat. In these viruses carried by bats among a considerable part belongs zoonosis viruses, their distribution and diffusion may be much more than people estimated to have wide. Therefore, bats for animal and human health poses a potential hazard, it seemed like a natural virus database.
