Question

what are viruses? How do they differ from other microbes?​

Answer 1

• A virus is a submicroscopic infectious agent that multiplies solely within an organism's live cells.
• Viruses infect all living things, from animals and plants to bacteria and archaea.
• Since Dmitri Ivanovsky's 1892 publication revealing a non-bacterial pathogen infecting tobacco plants and Martinus Beijerinck's 1898 discovery of the tobacco mosaic virus, more than 9,000 viral species have been characterized in detail out of the millions of varieties of viruses in the environment.
• Viruses are the most common sort of living organism and may be found in practically every environment on Earth.
