Rod shaped virus- Tobacco mosaic virus
Tobacco mosaic virus is a rod-shaped virus with a helical capsid.



Respiratory infections- Adenovirus
Adenoviruses are icosahedral shaped DNA viruses that cause a range of diseases related to the respiratory tract, for example- bronchitis, pneumonia.




Proteinaceous infectious agents- Prions
Prions are misfolded proteins that can cause diseases like bovine spongiform encephalopathy (BSE) or mad cow disease.



Bacterial virus- Bacteriophage
Bacteriophages are viruses that infect bacteria. The structure contains
Head, collar and ends with a base plate containing long tail fibres.
