In this article we will discuss about the replication cycle of rabies viruses. The infection process is initiated with adsorption of virus on the host cell. Interaction takes place between spike G protein and specific cell surface receptors. It results in fusion of the rabies virus envelope with the host cell membrane. After adsorption, the virus penetrates the host cell [...]
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 [...]
