Antibiotic Resistance

Antibiotic Resistance

Antibiotic drugs can save lives. But some germs get so strong that they can resist the drugs. This is called resistance. The drugs don't work as well. Germs can even pass on resistance to other germs.
Antibiotics normally work by killing germs called bacteria. Or they stop the bacteria from growing. But sometimes not all of them are stopped or killed. The strongest ones are left to grow and spread. A person can get sick again. This time the germs are harder to kill.
The more often a person uses an antibiotic, the more likely it is that the germs will resist it. This can make some diseases very hard to control. It can make you sick longer and more doctor visits.You may need to take drugs that are even stronger.
