Bacteria live in or on every one of us. Most are useful to us, for example, they help to digest our food. But some bacteria can make us ill. We sometimes need antibiotics to make us better again. Antibiotics are drugs that kill bacteria or slow their growth. This helps the body to heal itself. A major disadvantage of antibiotics is that bacteria can become invulnerable to them. We call this resistance. That's why doctors need to be reluctant to prescribe antibiotics. The more often you use antibiotics, the greater the risk that bacteria will become resistant. Infections with resistant bacteria are more difficult to treat.
