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 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 [...]
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 [...]
