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 [...]
In this article we will discuss about the assembly, evolvement and release of herpesviruses. Assembly of Herpesviruses: There are more than 30 HSV-1 gene products that act as the structural components of the virion. These are expressed with late kinetics. Capsid assembly i.e. enveloping is a complex process. The general outline of the process was established by careful electron microscopic [...]
