What are the viruses
Usually the smallest creatures on the planet are bacteria. But, if you plunge deeper into the world of dwarfs among living organisms, it becomes clear that the smallest should not be considered bacteria, but viruses. Just imagine that about a hundred thousand are placed on the tip of a sewing needle of viruses!
The question is, why are bacteria considered the smallest creatures?
The fact is that viruses, before they enter a living organism, behave like a large organic molecule.
Only after viruses enter the living organism of a plant, animal or human, it begins to multiply and, like all living things, pass on their inherent properties by inheritance.
Viruses are a mystery to scientists. Some scientists consider them living organisms, while others are not inclined to attribute them to the world of wildlife. The sizes of these mysterious creatures range from 20 to 300 and even 500 nanometers, and a nanometer is equal to one billionth of a meter. Normal sized viruses cannot be seen with a light microscope. Giant viruses, that is, viruses whose dimensions exceed the norm of 200 nanometers, can already be examined using a conventional light microscope. In 1992, in England, scientists were faced with a virus, the size of which struck them. The virus was hiding in the body of amoebae and was so large that initially scientists thought it was a bacterium. Thus, the virus received the name mimivirus. Mimivirus was the source of an outbreak of pneumonia in England in 1992. However, later it turned out that mimivirus is not a giant in the world of viruses. A new virus called mamavirus has replaced mimivirus among giants. The size of this virus is much larger than the size of some bacteria.
More recently, scientists have discovered a group of giant viruses that are many times superior to previous “champions”. These viruses are called Marseleviruses.
