The discovery of penicillin by Alexander Fleming in 1928 ushered in the golden age of antibiotics. For the first time in human history, bacterial infections that were once death sentences—such as pneumonia, tuberculosis, and sepsis—became manageable, curable conditions. However, just over nine decades later, this medical miracle is waning. The rise of antimicrobial resistance (AMR), commonly known as antibiotic resistance, is now recognised by the World Health Organization (WHO) as one of the top ten global public health threats facing humanity.
Antibiotic resistance occurs when bacteria evolve to survive exposure to drugs that would normally kill them. This is a natural evolutionary process, but it has been drastically accelerated by human behaviour. The primary drivers are twofold: overuse and misuse in human medicine, and the rampant use of antibiotics in agriculture. In many countries, antibiotics are prescribed for viral infections like the common cold—against which they are entirely ineffective—or patients fail to complete their prescribed courses, allowing partially resistant bacterial strains to survive and multiply. Simultaneously, an estimated 70-80% of all antibiotics sold globally are used in livestock and aquaculture, not to treat disease, but to promote growth and prevent infection in crowded, unsanitary conditions. This creates an immense reservoir of resistant bacteria that can transfer to humans through the food chain and the environment.
The consequences of this trend are already visible. Common infections, such as urinary tract infections (UTIs), pneumonia, and gonorrhoea, are becoming increasingly difficult to treat. A patient with a resistant infection may require second- or third-line drugs, which are often more toxic, more expensive, and require longer hospital stays. In the worst cases, doctors are forced to revert to ‘last-resort’ antibiotics like colistin, a drug so toxic it can cause kidney failure. When colistin fails, the infection becomes untreatable. According to a 2019 report by the UN Ad Hoc Interagency Coordinating Group on Antimicrobial Resistance, at least 700,000 people die each year from drug-resistant diseases. If no action is taken, this number is projected to rise dramatically: to 10 million deaths per year by 2050, surpassing cancer as a leading cause of death.
Compounding this crisis is the stagnation of the antibiotic pipeline. The ‘golden age’ of antibiotic discovery ended decades ago. Large pharmaceutical companies have largely abandoned antibiotic research due to poor financial incentives. A new cancer drug can be sold for thousands of dollars per dose and taken for months; a new antibiotic, by contrast, must be used sparingly to prevent resistance, and for short durations, making it far less profitable. Consequently, only two new classes of antibiotics have reached the market in the last 50 years. Even when new drugs are developed, resistant strains often emerge within a few years of their introduction.
Addressing the growing global threat of antibiotic resistance requires a coordinated ‘One Health’ approach that recognises the interconnectedness of human, animal, and environmental health. Key strategies include: improving infection prevention through vaccination and hygiene, reducing unnecessary agricultural use, investing in rapid diagnostic tests to distinguish viral from bacterial infections, and creating new economic models to incentivise antibiotic research. Countries like the United Kingdom have introduced ‘subscription’ models, where governments pay pharmaceutical companies upfront for access to antibiotics, regardless of how many doses are sold.
International bodies such as the WHO, the Food and Agriculture Organization (FAO), and the World Organisation for Animal Health (OIE) have launched a Global Action Plan on AMR, which over 150 countries have signed. However, implementation remains inconsistent, particularly in low- and middle-income countries where regulatory oversight is weak and antibiotics are often available without a prescription. The COVID-19 pandemic demonstrated how quickly a global health threat can escalate when preparedness is lacking. Antibiotic resistance is slower moving, but far more insidious. It represents a silent pandemic—one that threatens to undo a century of medical progress.

Passage:
The growing global threat of antibiotic resistance
Antibiotic resistance is one of the biggest threats to global health, food security, and development today. Antibiotic resistance happens when bacteria change and become resistant to the antibiotics used to treat infections. This means that antibiotics are no longer effective in killing the bacteria, making infections harder to treat.
The overuse and misuse of antibiotics in human medicine and agriculture are key drivers of antibiotic resistance. In human medicine, antibiotics are often prescribed unnecessarily or used incorrectly, which accelerates the development of resistance. In agriculture, antibiotics are used to promote growth and prevent disease in livestock, which also contributes to the emergence of resistant bacteria.
The consequences of antibiotic resistance are severe. Infections caused by resistant bacteria are more difficult to treat and can lead to longer hospital stays, higher healthcare costs, and increased mortality. Moreover, the loss of effective antibiotics threatens our ability to treat a wide range of infections, from common illnesses like pneumonia and tuberculosis to life-threatening conditions like sepsis and meningitis.
Questions and Answers:
Answer: Antibiotic resistance occurs when bacteria change and become resistant to the antibiotics used to treat infections. This happens when bacteria are exposed to antibiotics and develop mechanisms to survive and multiply.

The Growing Global Threat of Antibiotic Resistance: IELTS Reading Answers and Insights
The growing global threat of antibiotic resistance has become a pressing concern for the World Health Organization (WHO) and other health experts worldwide. The increasing ineffectiveness of antibiotics against bacterial infections poses a significant risk to global health, making it essential to understand the issue, its causes, and potential solutions. In this article, we will explore the topic of antibiotic resistance, provide IELTS reading answers, and offer insights into the growing global threat.
What is Antibiotic Resistance?
Antibiotic resistance occurs when bacteria develop the ability to survive and thrive despite the presence of antibiotics. This happens when bacteria are exposed to antibiotics, and those that are susceptible to the medication die, leaving behind resistant bacteria that multiply and spread. Over time, the resistant bacteria become dominant, making antibiotics ineffective against infections.
Causes of Antibiotic Resistance
The overuse and misuse of antibiotics are primary contributors to the development of antibiotic resistance. The widespread prescription of antibiotics for viral infections, such as the common cold, and the use of broad-spectrum antibiotics, have accelerated the emergence of resistant bacteria. Additionally, the lack of new antibiotics being developed and the inadequate infection control practices in healthcare settings have exacerbated the problem.
The Global Threat of Antibiotic Resistance
The World Health Organization (WHO) has identified antibiotic resistance as a significant global health threat. The organization's report on antibiotic resistance highlights the growing concern:
"The world is facing a growing threat from antimicrobial resistance, which could have serious consequences for health and economies if not addressed."
The consequences of inaction will be severe, with estimates suggesting that by 2050, antibiotic resistance could cause 10 million deaths annually, surpassing cancer as a leading cause of death.

Drivers and Consequences of Antibiotic Resistance
The rise of antibiotic resistance is not a simple medical problem but a complex interplay of human behaviour, agricultural practices, and economic pressures. One major driver is the overprescription of antibiotics by healthcare providers, often in response to patient demand or diagnostic uncertainty. Viral infections, against which antibiotics are useless, are frequently treated with antibiotics, promoting resistance without any benefit.
In agriculture, up to 80% of total antibiotic consumption in some countries is used in food animals to promote growth and prevent disease in crowded conditions. This practice allows resistant bacteria to develop in animals and spread to humans through direct contact, food, or the environment. Waste from farms and pharmaceutical manufacturing also releases antibiotics into water systems, creating reservoirs of resistance genes.
Hospital-acquired infections (HAIs) pose a particularly severe threat. Immunocompromised patients are vulnerable to resistant strains like carbapenem-resistant Enterobacteriaceae (CRE), which are resistant to last-resort antibiotics. The economic burden is staggering: in the USA alone, treating resistant infections costs an estimated $4.6 billion annually. Patients with resistant infections stay in hospital longer, require more expensive drugs, and have mortality rates up to twice as high as those with treatable infections.
The pipeline for new antibiotics is drying up. Between 2010 and 2020, only ten new antibiotics were approved, and most were variations of existing classes. Pharmaceutical companies have little financial incentive to develop new drugs because antibiotics are used for short courses and resistance limits their long-term profitability.
A. The discovery of antibiotics in the 20th century is often cited as one of the greatest achievements in medical history. Penicillin, discovered by Alexander Fleming in 1928, transformed once-fatal infections into manageable conditions, saving countless lives. However, this medical triumph is facing a formidable adversary: antibiotic resistance. This phenomenon occurs when bacteria evolve mechanisms to withstand the drugs designed to kill them. As a result, standard treatments become ineffective, infections persist, and the risk of spreading resistant strains to others increases.
B. The mechanism of resistance is a classic example of Darwinian evolution. When a person takes an antibiotic, the drug kills the susceptible bacteria, leaving behind only those few bacteria that, by chance or genetic mutation, possess traits allowing them to survive. These survivors then multiply, becoming the dominant strain. This process is accelerated significantly by the misuse and overuse of antibiotics. When drugs are used unnecessarily—for instance, to treat viral infections like the common cold, against which they are ineffectual—bacteria are exposed to the medication without fully eradicating the infection, providing an environment for resistance to flourish.
C. While the natural biological mutation of bacteria is a slow process, human activity has rapidly escalated the crisis. In many parts of the world, antibiotics are readily available over the counter without a prescription, leading to self-medication and improper dosing. Furthermore, the agricultural sector is a major driver of resistance. Farmers frequently administer antibiotics to livestock not only to treat illness but also to promote growth and prevent disease in crowded conditions. This sub-therapeutic usage creates a reservoir of antibiotic-resistant bacteria that can be transmitted to humans via the food chain or through environmental contamination.
D. The implications of a "post-antibiotic era" are profound. Routine medical procedures that rely on prophylactic antibiotics, such as joint replacements, organ transplants, and cancer chemotherapy, would become life-threateningly risky. Common infections, such as pneumonia, tuberculosis, and blood poisoning, could once again become fatal. The World Health Organization (WHO) has warned that antibiotic resistance threatens the very core of modern medicine and could result in a global economic burden comparable to the 2008 financial crisis, due to prolonged hospital stays and lost productivity.
E. Addressing this growing threat requires a multifaceted approach. On an individual level, patients must adhere strictly to prescribed courses of treatment and avoid demanding antibiotics for viral illnesses. Policymakers are urged to implement stricter regulations on the sale of antibiotics and invest in better diagnostic tools to ensure drugs are only prescribed when necessary. Simultaneously, there is a pressing need to stimulate pharmaceutical research. The development of new antibiotics has stalled in recent decades because the financial return on drugs that are used sparingly is low. Without a renewed commitment to innovation and stewardship, the world risks returning to a time where a simple scratch could prove fatal.
Antibiotic resistance is one of the most urgent global health threats today. Bacteria exposed repeatedly or improperly to antibiotics evolve mechanisms that render those drugs ineffective, leaving previously treatable infections dangerous or deadly. The problem spans healthcare, agriculture, and community settings and is driven by overuse, misuse, and limited new drug development.
