Answer :
The correct statement regarding antibiotic resistance in bacteria is:
- Humans are using antibiotics more frequently, and that is causing the development of more antibiotic resistant strains.
Explanation
What is Antibiotic Resistance?
- Antibiotic resistance occurs when bacteria change in a way that reduces or eliminates the effectiveness of antibiotics designed to cure or prevent infections. The bacteria survive and continue to multiply, causing more harm.
Why Does Antibiotic Resistance Happen?
- Overuse and Misuse of Antibiotics: The frequent use of antibiotics, even when not needed, can lead to antibiotic resistance. For example, taking antibiotics for viral infections like the common cold or flu, where they have no effectiveness, contributes to this problem.
- Incomplete Courses of Antibiotics: Not completing prescribed antibiotic courses allows some bacteria to survive and become resistant.
- Use in Agriculture: Antibiotics are often used in livestock to promote growth and prevent disease in crowded conditions, which contributes to the development of resistant strains.
Consequences of Antibiotic Resistance:
- Treating infections becomes more difficult, leading to longer hospital stays, higher medical costs, and increased mortality.
- Resistant infections can spread to others, making it a public health issue that demands international attention.
How to Combat Antibiotic Resistance:
- Appropriate use of antibiotics: Only using antibiotics when prescribed by a healthcare professional.
- Public Awareness: Educating the public about the appropriate use of antibiotics and the dangers of resistance.
- Research and Development: Encouraging the development of new antibiotics and alternative treatments.
In summary, option 3 is the most accurate representation of the current situation regarding antibiotic resistance. Increased use and misuse of antibiotics directly drive the emergence of resistant bacterial strains.
