Governments must enforce stricter regulations on how antibiotics are prescribed and sold. Medical professionals require continuous training on antibiotic stewardship, while public awareness campaigns must educate patients that antibiotics do not cure viral illnesses.
Using viruses to combat bacterial infections is a completely new concept discovered in the 21st century. Questions 6–10
Explanation: Paragraph B describes complacency in the 1980s, resistance increasing due to overuse, and reaching a point where some infections have no available agents. This traces the historical evolution of the resistance problem.
The discovery of penicillin instantly removed all global anxiety regarding bacterial diseases. Bacteria reproduce rapidly
Explanation: Paragraph C contains Joe Cranston's direct quote: "'Whenever antibiotics are used, there is selective pressure for resistance to occur. More and more organisms develop resistance to more and more drugs,' says Joe Cranston." This perfectly matches the statement..
For your post, you can highlight these four critical areas covered in the passage:
While resistance is a natural evolutionary phenomenon, human activity has accelerated the process to a catastrophic pace. The primary driver is the misuse and overuse of antibiotics in both human medicine and agriculture. vulnerable organisms are eradicated
Passages frequently state: "Antibiotic resistance is a natural phenomenon." This is TRUE . The problem is that human activity accelerates it.
However, the euphoria surrounding these miracle drugs fostered a dangerous complacency. Fleming himself, during his 1945 Nobel Prize acceptance speech, issued a prophetic warning: the public misuse of penicillin could easily educate microbes, rendering them resistant to treatment. Decades later, this warning has manifested as a stark global reality. The pipeline for novel antibiotic development has largely dried up due to low economic returns for pharmaceutical companies, while the efficacy of existing first- and second-line treatments continues to erode at an alarming velocity. Section 2: Mechanisms of Bacterial Defiance
An explanation of how industrial farming practices contribute to drug resistance. resistance increasing due to overuse
The Growing Global Threat of Antibiotic Resistance The rise of drug-resistant bacteria is one of the most pressing public health crises of the twenty-first century. Often referred to as a "silent pandemic," antibiotic resistance threatens to undo decades of medical progress, turning once-treatable infections into fatal diseases. In the context of academic examinations like the International English Language Testing System (IELTS), this topic frequently appears in the Academic Reading component due to its complex vocabulary, scientific relevance, and argumentative nature.
To comprehend the scale of the threat, it is essential to understand the evolutionary biology that drives bacterial adaptation. Bacteria reproduce rapidly, often dividing every twenty minutes under optimal conditions. This accelerated lifecycle allows for a high frequency of genetic mutations. When a population of bacteria is exposed to an antibiotic, vulnerable organisms are eradicated, leaving behind a resilient minority possessing genetic traits that shield them from the drug's mechanism of action.
