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 [...]
In this article we will discuss about the structure of adenoviruses (explained with diagram). All adenovirus particles are similar; particles are medium-sized, non-enveloped having 90-100 nm diameters (Fig. 17.5). The particles have icosahedral symmetry which can easily be visible in the electron microscope by negative staining. Viral particles are composed of 252 capsomers: 240 hexons forming the faces and 12 [...]
