Why do antibiotic not affect viruses?

why do antibiotic not affect viruses? (like DNA, host cell?)



Why do antibiotic not affect viruses?anti virus protection



The bulk of antibiotics work by affecting cellular metabolism and or disrupting chemical processes in living organisms. a virus is inert outside of a cell. and anything that can kill a host cell can kill a host. thus antibiotics have no affect on a virus..



anti virals tend to disrupt the viral DNA processes to stop Viral replication within the host cell.

Because they are meant to work on bacteria, thats why we have antivirals (they aren't very good compared to the original effectivness of most antibiotics). Antibiotics work on bacteria machinery, like their cell wall and other parts that they have that we do not have. If we damage these parts, we will not be affected nor anything else without those parts. Viruses do not have these parts and so are not affected.
Antibiotics are taken for a specific living things. However, viruses are actually not a living organism and not specific ones, it is impossible to class them in groups. It is experimentally claimed that viruses can change their own genome (that can be RNA or DNA) into host genomes. For example, when HIV virus infects a cell, it directly comes into a host nucleus and adds its own genome to the host genome, therefore it creates a new host DNA. Thus it also leads to change the host genome sequence. For this infection it can not be possible to find appropriate antibiotics because the antibiotics can not be produced for each person. So our body has its own specific protein,MHC class proteins, to prevent to spread this deadly infection. (immune system)
