A description of how farming practices contribute to environmental contamination.
The overuse of antibiotics has led to the development of antibiotic-resistant bacteria, which are bacteria that can survive and thrive despite the presence of antibiotics. According to the World Health Organization (WHO), antibiotic resistance is one of the biggest threats to global health, food security, and development. This article explores the core concepts of this
2. Causes of Antibiotic Resistance (Common IELTS Reading Themes)
An explanation of how resistant traits are shared between different species of bacteria.
Patients often stop taking antibiotics once they feel better, allowing the hardiest bacteria to survive and develop resistance.
The crisis extends beyond hospitals and into the food chain. Livestock are frequently fed antibiotics, which has turned farms and abattoirs into breeding grounds for inter-species infection. Resistant bacteria can survive on animal carcasses, contaminating meat purchased by consumers. Furthermore, animal faeces used as manure can spread these resilient bacteria to crops, creating a cycle of contamination that is difficult to break. Over-prescribing for viral infections (like colds) fuels the
The economic implications of this biological threat are catastrophic. When first-line antibiotics fail, doctors must resort to second- or third-line drugs. These alternative medications are frequently significantly more expensive, require longer hospital stays, and carry a higher risk of severe side effects. For example, treating multi-drug-resistant tuberculosis requires months of painful intravenous therapy rather than a simple course of oral pills. The financial strain on global healthcare systems is immense, and the loss of labor productivity threatens to destabilize fragile economies.
Preventive treatment, often misused in agriculture.

What is a consequence of antibiotic resistance?
Horizontal gene transfer requires bacteria to be from the identical species to pass on resistance genes.
Exacerbating the biological threat is a severe market failure within the global pharmaceutical sector. Developing a novel antibiotic requires billions of dollars in research and development, paired with a high probability of clinical trial failure. Even when a pharmaceutical company successfully brings a breakthrough antibiotic to market, clinicians rightfully hoard it as a drug of last resort, using it sparingly to prevent bacteria from developing immediate resistance. Consequently, sales volumes for new antibiotics are inherently low. Compared to lucrative chronic-disease medications for hypertension or diabetes, which patients consume daily for decades, antibiotics offer an incredibly poor return on investment. As a direct result, almost all major pharmaceutical conglomerates have completely abandoned their antimicrobial research pipelines.
Paragraph C focuses on human behaviors causing the problem, explicitly citing "profound misuse and overuse," patients demanding drugs for viral infections, and doctors prescribing broad-spectrum options prematurely. 4. ii (How agricultural practices fuel the crisis) The overuse of antibiotics has led to the
