Antibiotics are important for fighting infections, but their overuse can lead to antibiotic resistance. This happens when bacteria develop ways to survive the effects of antibiotics. Scientists have found that the genes responsible for antibiotic resistance in harmful bacteria originally came from other bacteria that produce antibiotics naturally. The more antibiotics are used, the more likely it is for resistance to develop. Researchers have studied how bacteria protect themselves from antibiotics and have found some combinations of antibiotics that work well together to combat resistance. By understanding how antibiotic resistance develops, we can better manage and prevent it in the future.
