AI overview

A virus is a tiny infectious agent that can only reproduce by entering living cells and taking over their machinery to make copies of itself. Viruses matter because they infect virtually all life on Earth—from humans and animals to plants and bacteria—making them one of the most important biological forces to understand for human health and ecology.

A virus is a small infectious agent that can replicate only inside the living cells of an organism. Viruses can infect all types of organisms, from animals and plants to bacteria and archaea (Koonin et al. 2006). Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants, and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, about 5,000 viruses have been described in detail(Dimmock et al. 2006), although there are millions of different types (Breitbart & Rohwer 2005). Viruses are found in almost every ecosystem on Earth and are the most abundant type of biological entity (Edwards & Rohwer 2005, Lawrence et al. 2009). The study of viruses is known as virology, a sub-speciality of microbiology. Virus particles (known as virions) consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information; a protein coat that protects these genes; and in some cases an envelope of lipids that surrounds the protein coat when they are outside a cell. The shapes of viruses range from simple helical and icosahedral forms to more complex structures. The average virus is
