Antibiotic Resistant Bacteria

Medically reviewed by Last updated on Apr 2, 2024.

How do bacteria become resistant?

Antibiotic medicines kill bacteria. When antibiotics are not used correctly, they may not kill all of the bacteria. The bacteria that an antibiotic does not kill can grow stronger. The antibiotic may not be able to kill the new bacteria. Bacteria can become resistant when the wrong type, wrong dose, or wrong treatment length of antibiotic is used. They can also become resistant to more than one type of antibiotic. This has made it harder to cure infections that used to be easily treated.
