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.
How does antibiotic resistance happen? When bacteria come in contact with an antibiotic or antibacterial, the weaker bacteria die, but stronger ones survive. When the strong bacteria multiply, more and more strong bacteria are produced that are resistant to the antibiotic.
