Virus endocytosis image.  A virus is a submicroscopic agent that replicates only inside the living cells of an organism. Viruses interact with all life forms, from animals and plants to microorganisms, including bacteria and archaea.  Virus endocytosis is a cellular process in which substances are brought into the cell. The majority of animal virus families use the essential cellular process of endocytosis to transfer their genetic material into the inside of the cell.  The several endocytosis mechanisms that are dominated by viruses include caveolae, macropinocytosis, clathrin-mediated endocytosis, and nonclathrin, noncaveolae routes.
