How bacteria become resistant to antibiotics
1. Bacteria can reproduce every 30 minutes, allowing for rapid evolution under ideal conditions
2. Doctors began using antibiotics in the 1940s to treat bacterial diseases
3. Antibiotics kill bacteria, but certain strains have evolved to be resistant
4. Mutation can make a bacterium resistant to antibiotics
5. Antibiotic-resistant bacteria survive and reproduce without competition, leading to the rise of the resistant strain
6. Resistant strains spread as people are not immune to them and there's no effective treatment
