The key difference between serum and antiserum is that serum is the straw coloured fluid component of blood without blood cells and clotting factors, while antiserum is antibody-rich serum obtained from an immunized animal or human. Viral proteins have replaced the ancestral bacterial RNA/DNA polymerases and primase during mitochondrial evolution. Beijerinck first surmised that the virus under study was a new kind of infectious agent, which he designated contagium vivum fluidum, meaning that it was a live. It is a single-stranded RNA virus with an icosahedral capsid and contains a protein envelope made of glycoproteins. All viruses are encased in a viral membrane. The virus uses the host cell's machinery to produce new copies of itself, and as it does so, it incorporates some of the host cell's plasma membrane into its own. They have a membrane-like outer covering. It can survive inside gastrointestinal tract 5. Non enveloped viruses: 1. Viruses can be divided into two main categories; enveloped viruses, which have a lipid membrane (envelope) that is derived from the host cell; and non-enveloped viruses, which lack a membrane. Envelope Glycoproteins and Viral Fusion. A. Viruses can have a lipid "envelope". Non-enveloped viruses require some form of membrane "perforation".
