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 [...]
The following points highlight the six main stages involved in the replication of animal viruses. The stages are: 1. Adsorption 2. Penetration 3. Un-Coating 4. Replication of Viral Genome 5. Synthesis and Assembly of Virus Capsids 6. Release of New Virus. Stage # 1. Adsorption: Adsorption to the host cell surface is the first step in reproduction cycle of animal [...]
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 [...]
