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) [...]
In this article we will discuss about:- 1. Meaning of Poliovirus 2. Morphology of Poliovirus 3. Replication 4. Cultivation. Meaning of Poliovirus: Poliovirus is a member of the enterovirus subgroup, family Picornaviridae. Picornaviruses are small, ether- insensitive viruses with an RNA genome. There are three poliovirus serotypes: serotype 1, 2, and 3. Serotype 1 is the common epidemic type, serotype [...]
