Study Notes
Antibiotics: History and Use
- Antibiotics are medications that fight microbes, including bacteria, viruses, fungi, and parasites.
- Broad-spectrum antibiotics work against many types of microbes, while narrow-spectrum antibiotics target a few.
- Antibacterials are the most common antibiotic type. Examples include ampicillin and penicillin.
Importance of Careful Use
- Antibiotics have significantly reduced illness and death from serious diseases, like meningitis, strep throat, and ear infections.
- Prior to antibiotics, these diseases often caused severe complications or death.
- Overuse and inappropriate use of antibiotics can lead to antibiotic resistance, diminishing their effectiveness.
Discovering Penicillin
- Alexander Fleming discovered penicillin inadvertently in 1928.
- He noticed that mold prevented bacterial growth on a petri dish.
- Penicillin's ability to kill bacteria was explored by researchers and tested on humans starting in 1941.
- It proved highly effective in treating bacterial infections.
- Its discovery won Fleming a Nobel Prize.
The Antibiotic Era
- Penicillin's success spurred further antibiotic development.
- Many types of antibiotics are now available.
- Millions of antibiotic prescriptions are written annually in the U.S., many for children.
Challenges with Antibiotics
- Antibiotic resistance is a growing problem.
- Some bacteria now resist penicillin and other antibiotics.
- Resistance makes some infections harder to treat, potentially requiring multiple antibiotic treatments.
- Doctors now carefully prescribe antibiotics to lessen resistance.
- Surveys show a drop in antibiotic prescriptions for common childhood respiratory infections.
Important Note
- Antibiotics should only be used as directed by a doctor.
- Following medical guidelines helps preserve their effectiveness in the longer term.
