Virus found in pig droppings raises many questions
A new type of virus has now been identified in Japan, which could redefine our complete understanding of viruses, their proliferation and spread.
The recent study by the Tokyo University of Agriculture and Technology (TUAT) found that a new type of virus could revolutionize our understanding of how viruses multiply and spread. The results of the study were published in the English-language journal "Infection, Genetics and Evolution".
How are viruses structured?
Unlike most other living organisms, viruses have no cells. Viruses are just a particle of genetic material (RNA or DNA) in a protein shell. A virus is able to infect a cell before replication.
Virus identified in pig droppings
In pig droppings, the researchers from Japan were able to identify a new type of virus called EV-G, which could change our complete understanding of viruses. The newly discovered virus is very different from everything that has previously been assumed about the infectious agents. The virus found during the examination has no structural proteins. This means that the recombinant virus cannot form virus particles.
Virus had no protein envelope
The special virus variant even lacked the protein envelope of other viruses. So the virus would not be able to penetrate a host alone, which raises the question: How can this virus actually survive?
New treatment options through the discovery?
The team theorized that this virus, and any potential imitators in nature, could exploit other viruses to transport and help target infections. However, more research is needed to better understand exactly how the newly identified virus works. Nevertheless, the discovery of the new virus could turn our understanding of viruses in general upside down. The research team hopes the results of the new study could open up ways to tackle some of the greatest biological threats to humanity.
More research is needed
The new findings open up insights into a completely new system of viral evolution. However, it is unclear to researchers how exactly this new virus originated, how it infects cells or how it develops. Future research should now explore these secrets of viral evolution. (as)
