Virusesare tiny agents that reside inside of living cells. These cells are the host. cells. In order to reproduce or replicate a virus has to have a host cell. There are
Pathogenesis is the process by which an infection leads to disease. Pathogenic mechanisms of viral disease include (1) implantation of virus at the portal of entry (2) local replication (3) spread to target organs (disease sites) and (4) spread to sites of shedding of virus into the environment. Factors that affect pathogenic mechanisms are (1) accessibility of virus to tissue (2) cell susceptibility to virus multiplication and (3) virus susceptibility to host defenses.
Some viruses may have evolved from bits of DNA or RNA that “escaped” from the genes of a larger organism. The escaped DNA could have come from plasmids (pieces of naked DNA that can move between cells) or transposons (molecules of DNA that replicate and move around to different positions within the genes of the cell).
For MHV-2 the endocytosis mechanism was further characterized: the virus is internalized by a clathrin-dependent pathway that does not depend on the eps15 adaptor . Endosomal pH acidification is a fusion trigger for many viruses such as influenza virus and vesicular stomatitis virus (VSV).
Virus replication. 1. Attachment: Viral proteins on the capsid or phospholipid envelope interact with specific receptors on the host cellular surface. This specificity … 2. Penetration: The process of attachment to a specific receptor can induce conformational changes in viral capsid proteins or …
The short answer to these questions is that viruses evolve. That is the “gene pool” of a virus population can change over time. In some cases the viruses in a population—such as all the f…
