VIRUSES ARE FROM LATIN, THAT IS POISON
The virus comes from the Latin language, which is poison. The discovery of the virus began when a German scientist, Adolf Mayer, in 1883 conducted research on tobacco mosaic disease. Mayer sprayed mosaic diseased tobacco leaf extract into healthy tobacco plants. Then the tobacco plants will stunt and appear striped on the color of the leaves. Mayer considers that the disease was caused by very small bacteria. In 1982, Russian scientist Dimitri Ivanowsky retested Mayer’s research. Ivanowsky filters tobacco leaf extract with a bacterial filter. However, the filtrate obtained keeps the healthy tobacco plants from being infected by mosaic disease. Ivanowsky also suspected that tobacco mosaic disease was caused by a very small bacteria or the bacteria produced a poison that could pass through the filter. A few years later, Martinus W. Beijenrinck conducted the same research as ivanowsky. Beijenrinck assumed that there was an infectious agent that reproduced and attacked the tobacco plant. However, Beijenrinck suspects that the infectious agent is different from bacteria because it cannot be propagated in agar medium. The Beijenrinck hypothesis was strengthened by research by Wendell Stanley, an American scientist, who can crystallize the infectious agent, the Tobacco Mosaic Virus (TMV). Viruses cannot be classified as cells because the virus does not have a nucleus and cytoplasm. Viruses can be said as inanimate objects and living things. Viruses are said to be living things while living in cells that reproduce, whereas as inanimate objects, viruses are called virions. Virion is a condition when a virus outside a host cell is only a microscopic particle that can crystallize. Virus originates from the Latin language, which is poison.
