What is antibiotic resistance?
Antibiotic resistance occurs when bacteria change so that antibiotic medicines can’t kill them or stop their growth. As a result, bacterial infections become extremely difficult to treat.
Why is antibiotic resistance a problem?
When antibiotic resistance happens, we don’t know it has happened until we treat someone. The antibiotic that had previously been successful suddenly stops working or becomes less effective. It takes time to realize what is happening, and meanwhile, you get sicker.
Why do healthcare providers use antibiotics?
You can find bacteria just about everywhere: in water, food and soil. Bacteria live on people’s skin (and animal fur) and inside bodies, too. Most bacteria don’t cause problems. In fact, some are beneficial. Healthy bacteria in the digestive system aid food digestion.
What are superbugs?
Over the years, various strains of bacteria have adapted to the medicines that typically kill them. They can fight back against the drugs. Called superbugs, these bacteria continue multiplying and causing infections despite treatment with several different antibiotics. There’s a chance that no antibiotic will work.

Anyone exposed to antibiotics is at risk for antibiotic resistance. Older people and those with weakened immune systems are more likely to develop serious bacterial infections that need antibiotic treatment. The combination puts them at higher risk for complications from antibiotic resistance.
How are antibiotic-resistant bacterial infections treated?
If an infection shows signs of antibiotic resistance, your healthcare provider may try a different drug. The new drug may have more severe side effects, and trying a different antibiotic also raises the risk of developing resistance to that drug.
How does antibiotic resistance happen?
How Antibiotic Resistance Happens. Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance. Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them.
How do antibiotics fight germs?
Antibiotics fight germs (bacteria and fungi). But germs fight back and find new ways to survive. Their defense strategies are called resistance mechanisms . Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.
What bacteria break down antibiotics?
Germs change or destroy the antibiotics with enzymes, proteins that break down the drug. Example: Klebsiella pneumoniae bacteria produce enzymes called carbapenemases, which break down carbapenem drugs and most other beta-lactam drugs. Bypass the effects of the antibiotic.
How did antibiotics help the world?
However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.
What is the name of the drug that treats infections?
Antimicrobials Treat Infections Caused by Microbes. Microbes are very small living organisms, like bacteria. Most microbes are harmless and even helpful to humans, but some can cause infections and disease. Drugs used to treat these infections are called antimicrobials .
What is Gram negative bacteria?
Example: Gram-negative bacteria have an outer layer (membrane) that protects them from their environment. These bacteria can use this membrane to selectively keep antibiotic drugs from entering. Get rid of the antibiotic.
Can Staphylococcus aureus be bypassed?
Example: Some Staphylococcus aureus bacteria can bypass the drug effects of trimethoprim . Change the targets for the antibiotic. Many antibiotic drugs are designed to single out and destroy specific parts (or targets) of a bacterium. Germs change the antibiotic’s target so the drug can no longer fit and do its job.
What is the FDA's role in antibiotic resistance?

Why are antibiotics used?
The use of antibiotics has saved millions of lives, but its pervasive use to treat any infection, whether serious, minor, or even viral has lead to the increase in antibiotic resistance. Antibiotics strictly target bacteria, but it is sometimes difficult to differentiate between viral and bacterial infections without costly tests. It is often less time-consuming and more cost effective to proactively prescribe antibiotics, rather than take precautions and prescribe only the correct treatment.
Why are antibiotics not taken for the entire prescribed course?
When antibiotics are not taken for the entire prescribed course, pathogenic bacteria can adapt to the presence of low dose antibiotics, and eventually form a population that is completely resistant to the antibiotic regardless of the dosage.
Can a hospital curb the spread of a pathogen?
Hospitals and clinics are seeing more and more patients with infections, and it is not always possible to curb the spread of a pathogen in a population. Identification, isolation or treatment of all infectious diseases are not often feasible, resulting in the addition of more pathogens to the local community.
Is antibiotic resistance a global threat?
Antibiotic resistance has become a global threat, and with Antibiotic Awareness Week, it is important to understand the series of events that have led the world to this predicament.
What are the causes of antibiotic resistance?
Causes of Antimicrobial (Drug) Resistance. Microbes, such as bacteria, viruses, fungi, and parasites, are living organisms that evolve over time. Their primary function is to reproduce, thrive, and spread quickly and efficiently. Therefore, microbes adapt to their environments and change in ways that ensure their survival.
How do bacteria become drug resistant?
Gene Transfer. Microbes also may get genes from each other, including genes that make the microbe drug resistant. Bacteria multiply by the billions. Bacteria that have drug-resistant DNA may transfer a copy of these genes to other bacteria. Non-resistant bacteria receive the new DNA and become resistant to drugs.
How do microbes adapt to their environment?
Therefore, microbes adapt to their environments and change in ways that ensure their survival. If something stops their ability to grow, such as an antimicrobial, genetic changes can occur that enable the microbe to survive. There are several ways this happens.
How much of antibiotics are used in agriculture?
More than half of the antibiotics produced in the United States are used for agricultural purposes. 1, 2 However, there is still much debate about whether drug-resistant microbes in animals pose a significant public health burden.
Do antimicrobials increase resistance?
However, there are additional societal pressures that act to accelerate the increase of antimicrobial resistance.
Do microbes survive in the presence of antimicrobials?
In the presence of an antimicrobial, microbes are either killed or, if they carry resistance genes, survive. These survivors will replicate, and their progeny will quickly become the dominant type throughout the microbial population.
Do hospitals use antimicrobials?
Hospital Use. Critically ill patients are more susceptible to infections and, thus, often require the aid of antimicrobials. However, the heavier use of antimicrobials in these patients can worsen the problem by selecting for antimicrobial-resistant microorganisms.
A Public Health Issue

Introduction
Scope of The Problem
- Antibiotic resistance is rising to dangerously high levels in all parts of the world. New resistance mechanisms are emerging and spreading globally, threatening our ability to treat common infectious diseases. A growing list of infections – such as pneumonia, tuberculosis, blood poisoning, gonorrhoea, and foodborne diseases – are becoming harder, and sometimes impossi…
Prevention and Control
- Antibiotic resistance is accelerated by the misuse and overuse of antibiotics, as well as poor infection prevention and control. Steps can be taken at all levels of society to reduce the impact and limit the spread of resistance.
Recent Developments
- While there are some new antibiotics in development, none of them are expected to be effective against the most dangerous forms of antibiotic-resistant bacteria. Given the ease and frequency with which people now travel, antibiotic resistance is a global problem, requiring efforts from all nations and many sectors.
Impact
- When infections can no longer be treated by first-line antibiotics, more expensive medicines must be used. A longer duration of illness and treatment, often in hospitals, increases health care costs as well as the economic burden on families and societies. Antibiotic resistance is putting the achievements of modern medicine at risk. Organ transplantations, chemotherapy and surgeries …
