The Growing Global Threat Of Antibiotic Resistance Ielts Reading Answers Verified !!hot!! Today
Pharmaceutical companies are making high profits from newly developed antibiotics.
Through natural selection and rapid reproduction, bacteria that survive exposure to an antibiotic pass on their resistance genes to offspring.
A massive volume of antibiotics is used in livestock, not for treating sick animals, but to promote growth and prevent disease in overcrowded conditions. This creates a breeding ground for resistant strains that can jump to humans [2].
While specific question numbers vary by test version, these are the verified answers for the most common question types: Pharmaceutical companies are making high profits from newly
Explanation: Paragraph D details the mechanisms by which bacteria resist antibiotics: altering cell walls, producing enzymes, mutating DNA, taking up DNA from other bacteria, and acquiring plasmids. This makes it the clear match for this heading.

Disease-causing microbes thwart antibiotics by interfering with their mechanism of action. For example, penicillin kills bacteria by attaching to their cell walls, then destroying a key part of the wall. The wall falls apart, and the bacterium dies. Resistant microbes, however, either alter their cell walls so penicillin can't bind or produce enzymes that dismantle the antibiotic. Antibiotic resistance results from gene action. Bacteria acquire genes conferring resistance in different ways. Bacterial DNA may mutate spontaneously. Drug-resistant tuberculosis arises this way. Another way is called transformation where one bacterium may take up DNA from another bacterium. Most frightening, however, is resistance acquired from a small circle of DNA called a plasmid, which can flit from one type of bacterium to another. A single plasmid can provide a slew of different resistances. This creates a breeding ground for resistant strains
: Resistance is a natural process, not just a man-made error. The Power of Hygiene
Antibiotic resistance occurs when bacteria evolve mechanisms to withstand the drugs designed to kill them. Unlike human resistance to viruses, which is an immunity, bacterial resistance is a survival tactic. When antibiotics are introduced into a biological system, they kill susceptible bacteria, but a few resistant germs may survive. These survivors then multiply, creating a new population of bacteria that the drug cannot destroy.

The consequences of antibiotic resistance are far-reaching and devastating. Infections caused by resistant bacteria are more difficult to treat, leading to increased morbidity and mortality. The World Health Organization (WHO) estimates that antibiotic resistance is responsible for at least 700,000 deaths annually, with this number expected to rise to 10 million by 2050.
The evidence of escalating harm is unambiguous. In England, for example, the UK Health Security Agency (UKHSA) reported that the total number of antibiotic-resistant infections in 2024 equated to an average of nearly . Cases of bacteraemia caused by antibiotic resistance—a life-threatening bloodstream infection—increased by 9.3% from 2023 to 2024, rising from 18,740 to 20,484 cases. The estimated number of deaths in people with a resistant infection also rose sharply, from 2,041 deaths in 2023 to 2,379 deaths in 2024—an increase of 338 deaths in a single year.
: Farms and abattoirs act as breeding grounds; bacteria spread through livestock and even food crops treated with contaminated manure.
