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 discus about the classification of animal viruses. Baltimore (2008) classified the animal viruses in the following seven groups according to the relationships between virion, nucleic acid and mRNA transcription Table (17.1). The RNA within the virion is known as plus (+) or sense strand because it acts as mRNA, whereas the newly synthesized RNA which [...]
In this article we will discuss about the entry of adenovirus in host cell through attachment and endocytosis steps. The virus enters into the host cell through the steps as given below: (a) Attachment: Attachment to cells is rather slow and takes several hours to reach a maximum. Viral entry occurs into the two stages. An initial interaction of the [...]
