How do antibiotics fight infection?

Antibiotics fight bacterial infections either by killing bacteria or slowing and suspending its growth. They do this by: attacking the wall or coating surrounding bacteria. interfering with bacteria reproduction.

Why do antibiotics work on virus?

Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.

What do antibiotics kill bacteria?

Antibiotics can kill bacteria by interfering with their normal intracellular functions (RNA, DNA and protein synthesis) or by weakening the bacteria’s cellular structure, causing the cell to break open or lyse. Unlike animal cells, bacterial cells have both a plasma membrane and a stiff outer cell wall.

How long to take antibiotics?

Most antibiotics should be taken for 7 to 14 days. In some cases, shorter treatments work just as well. Your doctor will decide the best length of treatment and correct antibiotic type for you.
