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 [...]
In this article we will discuss about the structure and replication of pox viruses. Structure of Pox Viruses: Oval or brick-shaped 200-400 nm long particles can be visualized by the best light microscopes. The external surface is ridged in parallel rows, sometimes arranged helically (Fig. 17.17). Viral particles (virions) are generally enveloped (external enveloped virion-EEV). The intracellular mature virion (IMV) [...]
