In this article we will discuss about the replication of influenza viruses. Influenza virus is transmitted from infected mammals through the air by sneezing. Sneezing creates aerosols which consist of several virus particles. Besides, influenza is also transmitted by saliva, nasal secretions, blood and faeces. Moreover, it also spreads through droppings of infected birds. These bodily fluids or contaminated surfaces [...]
In this article we will discuss about the replication of reoviruses. The virus can enter the host cell via a receptor on the cell surface. The receptor is not known but is thought to include sialic acid (haeinagglutination, broad cell tropism), and junctional adhesion molecules (JAMs). Virus particles are internalized and partially uncoated by proteases in the endo-lysosomes/lysosomes in the [...]
In this article we will discuss about the replication of herpesviruses. Sequential interaction takes place between specific viral membrane glycoproteins and cell membrane receptors (e.g. cell surface proteoglycans which are heparin sulphates). On the basis of complementary residues present on host cell and viral membrane, binding between virus and host cell membrane takes place before entering the virus within the [...]
