Antibiotic resistance is the ability of bacteria to resist the effects of an antibiotic â that is, the bacteria are not killed, and their growth is not stopped. Resistant bacteria survive exposure to the antibiotic and continue to multiply in the body, potentially causing more harm and spreading to other animals or people.
Bacteria become resistant more quickly when antibiotics are used too often or are not used correctly (such as not taking a full course of antibiotics as prescribed by your doctor). Bacteria that are resistant to one antibiotic can sometimes be treated with other antibiotics.ntibiotics are strong medicines used to treat infections, including life-threatening contagious diseases. But antibiotics can cause more harm than good when they aren't used the right way. You can protect yourself and your family by knowing when you should use antibiotics and when you should not.
