Many soil-dwelling bacteria produce molecules that can be naturally synthesized and kill other species of bacteria. What are these bacteria-killing molecules called antibiotics
Antibiotics are effective pills which can be usually safe. Although they are very helpful in fighting disease, antibiotics can actually be harmful. Important Facts About Antibiotic Safety: Antibiotics can cause side effects such as allergic reactions and severe and potentially life-threatening diarrhea caused by the bacterium Clostridium difficile (C. diff).
Antibiotics can also interfere with other medications you may be taking. Antibiotic side effects account for nearly one-fifth of emergency room visits. These conditions are the most common reasons for emergency room visits for children under the age of 18. Taking antibiotics you don't need unnecessarily exposes you to the drug's side effects and denies you the benefits.
