NEET BIOLOGY

Detailed explanation-1: -Why don’t antibiotics work on viruses? Viruses are different to bacteria; they have a different structure and a different way of surviving. Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat.

Detailed explanation-2: -Antibiotics damage the cell wall of living organisms leading to their death. The viruses do not have a cell wall. Antibiotics are produced by bacteria and fungi that treat bacterial infections, not viral infections because viruses use host cells to perform their activities. So, they cannot kill viruses.

Detailed explanation-3: -Antibiotics do not kill viruses. Viral infections are almost always cured by your body’s own immune system. Based on your history and physical examination, it is likely that your illness is caused by a virus. Your illness is unlikely to be helped by an antibiotic.

Detailed explanation-4: -The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis.

Detailed explanation-5: -Antibiotics work by destroying the cell wall of bacteria or targeting the machinery of the growth of bacteria. Antibiotics are used against bacterial infection and cannot kill viruses. The mode of replication and structure of viruses are different from that of bacteria.
