Why are antibiotics important?

Antibiotics are type of drugs that are used to treat many diseases. These drugs attack microorganisms like bacteria which cause many infections like tonsillitis and boils. Antibiotics damage the multiplying bacteria and are harmless to the human cells. Bacteria have a thick cell wall that can fight against our body's defense mechanism.


They reproduce by dividing and re-forming their cell walls into new cells. The antibiotics stop this reproduction process of the bacteria by either killing them, or weakening them so that they get destroyed by the body s defense system. Penicillin was the first antibiotic to be discovered. Antibiotics work very well against all bacteria, but not against all viruses.
