The fourth step in the viral cycle is replication, which is defined by the rapid production of the viral genome. How a virus undergoes replication relies on the type of genetic material the virus possesses. Based on their genetic material, viruses will hijack the corresponding cellular machinery for said genetic material.
Rabies virus is estimated to cause around 55,000 deaths per year across the world [13] and has a death rate of nearly 100%. [14] These statistics coupled with the fact that there is currently no specific treatment, or antiviral drug [ 13 ] makes research on the virus of vital importance for the scientific community in order to possibly lower ...
Transmission electron micrograph of Tobacco mosaic virus, the first virus to be discovered and a ribovirian. Diseases caused by viruses in Riboviria have been known for much of recorded history, though their cause was only discovered in modern times. Tobacco mosaic virus was discovered in 1898 and was the first virus to be discovered. [56]
Replication cycle of vesicular stomatitis virus (VSV) Viral replication is cytoplasmic. The replication cycle is the same for most rhabdoviruses. All components required for early transcription and the nucleocapsid are released to the cytoplasm of the infected cell after the first steps of binding, penetration and uncoating take place. [9]
Rabies is caused by a number of lyssaviruses including the rabies virus and Australian bat lyssavirus. [4] Duvenhage lyssavirus may cause a rabies-like infection. [33] The rabies virus is the type species of the Lyssavirus genus, in the family Rhabdoviridae, order Mononegavirales.
After completing this process and infecting a dog with the resulting virus, Pasteur realized that the virus was less virulent. [7] Mostly, Pasteur worked with the rabies virus in rabbits. [8] Ultimately, to create his vaccine for rabies, Pasteur used a simple method that involved drying out tissue. As is described in his notebook:
To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.
A virus can induce changes in composition and organization of host cell cytoskeletal and membrane compartments, depending on the step of the viral replication cycle. [1] This process involves a number of complex interactions and signaling events between viral and host cell factors.
