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 discuss about the replication of adenoviruses. Adenovirus replicates inside the nucleus (Fig. 17.9). By the DNA replication process, the adenovirus multiplication cycle is separated into two phases i.e., an early phase and a late phase. In both phases a primary transcript is formed which is spliced to produce monocistronic mRNA which is compatible with the [...]
In this article we will discuss about the structure of influenza viruses (explained with diagram). Particles of influenza virus are highly pleomorphic, mostly spherical having 80-120 nm diameter. But it also occurs in other form like long filamentous particles (2,000 nm long, and 80-120 nm diameter). They have helical symmetry also. The outer surface of the viral particle consists of [...]
