Togaviruses: Structure and Replication | Microbiology

In this article we will discuss about the structure and replication of togaviruses. Structure of Togaviruses: The virus is enveloped and forms spherical particle of 65-70 nm diameter. It includes icosahedral capsid, which is made up of 240 monomers (Fig. 17.26). It has a triangulation number of (74). Envelope consists of 80 trimer spikes; dimension of each spike is 3xE1/E2 [...]

Structure of Influenza Viruses (With Diagram) | Microbiology

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 [...]

Structure of Herpesviruses (HSV) | Microbiology

In this article we will discuss about the structure of herpesviruses (explained with diagram). All of them are morphologically identical. They are large with a varying diameter from 140-170 nm. The nucleocapsid is spherical icosahedral and of about 100 nm diameter which is enclosed in a 30 nm thick glycoprotein lipid envelope. Thickness of the envelope indicates for the presence [...]
