In this article we will discuss about the structure of rabies viruses (explained with diagram). Rhabdo-viruses have a unique bullet-shaped appearance measuring about 180 × 75 nm. They have an envelope with prominent spikes on surface but not very variable in appearance. Spikes are made up of G protein that haem-agglutinate RBCs. The envelope is lined by the matrix protein [...]
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 [...]
In this article we will discuss about the structure of reoviruses (explained with diagram). Non-enveloped, icosahedral virion with a double capsid structure (e.g. rotavirus and orthoreovirus) where iuter capsid has an icosahedral T=13 symmetry, and inner capsid an icosahedral 7=2 symmetry. The outer capsid is positioned upon the virion in such a way that the capsomeres of each capsid layer [...]
