Some governments and international organizations are investing billions of dollars to tackle the problem, but many analysts say its scope and immediacy require a globally coordinated response. Introduced in the late 1920s with the discovery of penicillin, antibiotics are a class of drugs used to treat bacterial infections.

They fall into a larger drug class, antimicrobials, which includes medications to fight microorganisms such as viruses, fungi, and parasites.

Antibiotics were mass produced during World War II, and their use soared in the second half of the twentieth century.

More than one hundred antibiotics have been developed. Doctors and health-care professionals rely on antibiotics as a primary treatment for common bacterial infections, including strep throat, tuberculosis, urinary tract infections, and some sexually transmitted infections. The drugs are also critical for patients whose immune systems have been weakened by chemotherapy or major surgery. “A lot of what we do every day in the hospital depends on having antibiotics work effectively,” says Kathy Talkington, an expert on antibiotics at the Pew Charitable Trusts.

A lot of what we do every day in the hospital depends on having antibiotics work effectively.

Antibiotics have contributed to a substantial decline in global deaths from some types of infections. For instance, the death rate for syphilis, a major public health crisis in the early twentieth century, plummeted after the introduction of penicillin to near zero by 1975.

More recently, antibiotics have prevented more than fifty-eight million tuberculosis-related deaths since 2000, according to the World Health Organization (WHO). Like all organisms, bacteria adapt and evolve to their environments through a

process

Therefore, the more antibiotics are used, the more opportunities bacteria have to improve their defenses, and the less effective antibiotics become.

Tens of billions of antibiotic doses are consumed around the globe annually, a large portion of which, health experts believe, is wasted on patients with viruses or other illnesses that do not respond to antibiotics. In the United States, the Centers for Disease Control and Prevention (CDC) estimates that at least one-third of all antibiotic prescriptions are unnecessary. The problem is likely worse in the dozens of countries where antibiotics can be bought over the counter or on the internet. In 2015, the WHO found that antimicrobials were available without a prescription [PDF] in more than half of the 133 countries that submitted data. Meanwhile, the demand for antibiotics shows little sign of abating.

Global consumption jumped 65 percent [PDF] between 2000 and 2015, driven largely by low- and middle-income countries, particularly Brazil, China, and India.

In some countries, antibiotics continue to be

doled

How does the agriculture industry contribute to the problem?

Antibiotics are also given to animals, particularly those

being

Farms are estimated to account for roughly 70 percent of total antibiotic sales in the United States; the proportion is even higher in some other countries.

Experts urge veterinarians to reserve antibiotics for sick animals, but breeders commonly use the drugs to prevent disease and boost animal growth, increasing their profits.

This overuse contributes to the spread of resistant bacteria, which can be transmitted from animals to humans through the food chain and in more indirect ways.

farming industry has often been reluctant to cooperate with scientists researching how antibiotic resistance is transmitted between species. However, consumer pressure has pushed some large companies, such as Perdue Farms, to curb their use of antibiotics.

Doctors and health-care providers have raised alarm in recent years about the proliferation of bacterial strains, sometimes referred to as superbugs, that are resistant to multiple drugs or even to all drugs on the market.

In a 2019 report, the CDC classified four types of bacteria as “urgent threats.” As a result, infections such as pneumonia, gonorrhea, and urinary tract infections are becoming far more difficult to treat. For example, the class of antibiotics most commonly used to treat

urinary

In the United States, the death toll from antibiotic-resistant infections is estimated to be more than thirty-five thousand per year, roughly on par with annual automobile fatalities. Some health analysts say that, without containment efforts, the world is on track for a post-antibiotic era in which superbugs could kill up to ten million a year by 2050. Resistance to antibiotics and other antimicrobials could also take a significant toll on the global economy. The World Bank projects [PDF] that antimicrobial resistance could cost $1 trillion to $3 trillion in lost output annually by 2030, with poor countries likely bearing the brunt of the impact.

The pipeline for new medications is running dry; no new class of antibiotics has been discovered since 1987.

Scientists have developed variations on existing drugs, but many say these are not sufficient to stay ahead of evolving bacteria and other microorganisms.

This is in part because many pharmaceutical companies in recent decades have shied away from the market for antibiotics, which is not as profitable as the market for drugs to treat chronic health conditions, such as heart disease and diabetes.

On top of this, inventing new drugs has become more difficult, which led many pharmaceuticals to abandon antibiotics R&D in the 1990s. “The kinds of resistance you are seeing now don’t seem to be amenable to yet another tweak to this particular class of molecule,” former pharmaceutical executive John Rex told PBS NewsHour . Many experts note the particular need for drugs that can halt what are known as gram-negative bacteria, which are among the toughest to treat.

Health experts, international organizations, and many governments have called for greater coordinated action to regulate antibiotic

use

In the United States, the Barack Obama administration launched an action plan in 2015, pledging more than $1 billion to develop new antibiotics, reduce inappropriate use of the drugs, and increase surveillance of drug-resistant strains. Trump administration vowed to continue implementing the plan, and a yearlong initiative it launched in 2018 drew commitments from more than

thirty

The United States has also partnered with the United Kingdom to launch one of the largest public-private initiatives to fight superbugs.

By mid-2019, the project had put more than $100 million into prospective drugs, including eight new classes of antibiotics, half of which target gram-negatives. The European Commission has backed an initiative to streamline research happening across the continent, while Group of Twenty (G20) nations opened their own research hub in May 2018. Another public-private partnership sponsored by the European Union has dedicated 700 million euros to antibiotic development.

Antibiotic resistance presents a classic example of the ‘tragedy of the commons.’ However, some governments have been reluctant to impose regulations, fearing that doing so could harm food security and economic growth or push lifesaving drugs further out of reach of millions of citizens. Many experts argue, however, that without populous countries, such as India and China, stepping up to restrict antibiotic use, efforts elsewhere will be undermined. Both of those countries have launched national action plans on antimicrobial resistance, along with more than seventy-five other states.

“Antibiotic resistance presents a classic example of the ‘tragedy of the commons,’” write economist Aidan Hollis and human rights lawyer Peter Maybarduk.

In addition to reducing inappropriate use and increasing investment in new antibiotics, they advocate for an international accord that would increase access to antibiotics for low-income populations. In 2016, the UN General Assembly convened a summit on antimicrobial resistance, marking the broadest collaboration yet to fight the growing threat.

Antibiotics can have side-effects, sometimes serious. Taking antibiotics also increases antibiotic resistance, which means that antibiotics may not work as well in the future.

The key features of the trials were: people had acute bronchitis, but not pneumonia or tuberculosis, and had been sick for less than 30 days; treatments were antibiotics, including deoxycycline, erythromycin, trimethoprim/sulfamethoxazole, azithromycin, cefuroxime, amoxicillin and co-amoxiclav; and treatments were compared with placebo or no treatment. reduced the likelihood of having a cough at 2 to 14 days from 50% to 33%—this means that about 17 fewer people out of 100 had a cough at 2 to 14 days; reduced the likelihood of having a night cough at 2 to 14 days from 45% to 30%—this means that about 15 fewer people out of 100 had a night cough at 2 to 14 days; reduced the number of hours of cough by 11 hours, although the difference could be as little as 1 hour to as much as 21 hours; reduced the number of hours of feeling ill by 15 hours, although the difference could be as little as 3 hours to as much as 28 hours; did not increase clinical improvement (having no limitations or being cured or being improved overall); and increased side-effects by from 19% to 23%—this means that about 4 more people out of 100 had

Patients with community-acquired pneumonia (CAP) and treated with penicillin-G/V had less severe pneumonia than patients treated with broad-spectrum antibiotics or combination therapy, according toВ a new studyВ conductedВ in Denmark.

CAP is the most frequent lethal infection in Europe, but antibiotic treatment for patients differs among

countries

According to researchers, as the diagnosis of the specific pathogen responsible for the infection may be difficult to obtain, the use of broad-spectrum antibiotics “is far more common than pathogen specific treatment.”.

The objective of the study was to investigate the epidemiology of CAP in Denmark and evaluate the prognosis of patients treated with penicillin-G/V monotherapy.
