If you are sick with a bacterial infection, the doctor will most likely prescribe you antibiotics. This type of medicine targets bad bacteria in your system so that you can feel better. Unfortunately, many antibiotic medications have a negative effect on healthy bacteria as well. The more we use antibiotics though, however positive the outcome may be, the more bacteria evolve. This creates strains of bacteria called superbugs, which can sometimes be resistant to antibiotics altogether. Medical researchers are looking into new treatments that control the spread of bacteria, but also prevent them from evolving.
- Our immune systems are good at fighting a variety of infections, and when they can’t antibiotics are prescribed.
- Antibiotics inhibit the growth, or kill the bacteria that is attacking the inside of the body.
- For a cold or flu, these are not prescribed, because we don’t know what type of bacteria we are dealing with.
“Before the development of antibiotics for widespread use, about 70 years ago, there was a high mortality rate from bacterial infections, such as tuberculosis, pneumonia, and sexually transmitted contagions.”
