Because of these resistant bacteria, some diseases that used to be easy to treat are now becoming nearly impossible to treat. Bacteria can develop resistance to certain medicines: Medicine resistance happens when bacteria develop ways to survive the use of medicines meant to kill or weaken them.
What to do if your child is on antibiotics?
If your child receives an antibiotic, be sure to give it exactly as prescribed to decrease the development of resistant bacteria. Have your child finish the entire prescription. Don't stop when the symptoms of infection go away. Never save the left over antibiotics to use "just in case.".
Can you treat a viral infection with antibiotics?
However, treating viral infections with antibiotics in order to prevent bacterial infections is not recommended because of the risk of causing bacterial resistance:
Do antibiotics kill viruses?
These are viruses and bacteria. Antibiotics cannot kill viruses or help you feel better when you have a virus. Antibiotics do kill specific bacteria. Some viruses cause symptoms that resemble bacterial infections, and some bacteria can cause symptoms that resemble viral infections.

The main types of antibiotics include:
What is the purpose of antibiotics?
Antibiotics. Antibiotics are a group of medicines that are used to treat infections caused by some germs (bacteria and certain parasites). They do not work against infections that are caused by viruses - for example, the common cold or flu.
Why are germs resistant to antibiotics?
Germs become resistant to antibiotics over time, which then makes them less effective. The World Health Organization (WHO) says "the world urgently needs to change the way it prescribes and uses antibiotics" as antibiotic resistance is a major global threat. Antibiotics.
What happens if you don't take antibiotics?
If you do not take your antibiotics in the right way it will affect how much of them get into your body (their absorption) and therefore they may not work as well. So, follow the instructions as given by your doctor and on the leaflet that comes with the antibiotic you are prescribed.
What is parasite in medicine?
A parasite is a type of germ that needs to live on or in another living being (host). Antibiotics do not work against infections that are caused by viruses (for example, the common cold or flu ), or fungi (for example, thrush in the mouth or vagina ), or fungal infections of the skin. Microbes, Germs and Antibiotics discusses the different types ...
What is the name of the bacteria that are resistant to antibiotics?
Other bacteria produce chemicals called enzymes such as extended-spectrum beta-lactamases (ESBLs) which allow them to be resistant to certain antibiotics.
What are the different types of antibiotics?
The main types of antibiotics include: Penicillins - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin. Cephalosporins - for example, cefaclor, cefadroxil and cefalexin. Tetracyclines - for example, tetracycline, doxycycline and lymecycline. Aminoglycosides - for example, gentamicin and tobramycin.
How do antibiotics help with infections?
They either kill bacteria or stop them from reproducing, allowing the body’s natural defenses to eliminate the pathogens. Used properly, antibiotics can save lives. But growing antibiotic resistance is curbing the effectiveness of these drugs. Taking an antibiotic as directed, even after symptoms disappear, is key to curing an infection and preventing the development of resistant bacteria.
How to prevent bacterial infection?
Wash your hands often. Washing with regular soap and rinsing with running water, followed by thorough drying, is considered the most important way to prevent disease transmission. Routine consumer use of residue-producing antibacterial products, such as those containing the chemical triclosan, have not been proven to confer health benefits and may actually contribute to antibiotic resistance.
Why are antiviral drugs so difficult to develop?
These medicines have been much more difficult to develop than antibacterial drugs because antivirals can damage host cells where the viruses reside. Today, there are more antiviral drugs for HIV than for any other viral disease, transforming an infection that was once considered a death sentence into a manageable chronic condition. But novel drugs are needed to combat other epidemic viral infections, such as influenza and hepatitis B and C.
What is NCBI bookshelf?
NCBI Bookshelf. A service of the National Library of Medicine, National Institutes of Health.
Why are antibiotics not profitable?
Major pharmaceutical companies have limited interest in dedicating resources to the antibiotics market because these short-course drugs are not as profitable as drugs that treat chronic conditions and lifestyle-related ailments, such as high blood pressure or high cholesterol. Antibiotic research and development is also expensive, risky, and time consuming. Return on that investment can be unpredictable, considering that resistance to antibiotics develops over time, eventually making them less effective.
Is infectious disease a fact of life?
Infectious disease may be an unavoidable fact of life, but there are many strategies available to help us protect ourselves from infection and to treat a disease once it has developed.
Can you use antibiotics for a virus?
Use antibiotics only for infections caused by bacteria. Viral infections cannot be treated with antibiotics. Your doctor may prescribe an antiviral medication if your condition warrants it.
When are antibiotics needed?
When Antibiotics Are Needed. Antibiotics are only needed for treating certain infections caused by bacteria. We rely on antibiotics to treat serious, life-threatening conditions such as pneumonia and sepsis, the body’s extreme response to an infection.
What are the benefits of antibiotics?
Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. Antibiotics aren’t needed for many sinus infections and some ear infections. Antibiotics can save lives, and when a patient needs antibiotics, the benefits usually outweigh the risks of side effects and antibiotic resistance. When antibiotics aren’t needed, they won’t help you, and the side effects could still cause harm. Common side effects of antibiotics can include: 1 rash 2 dizziness 3 nausea 4 diarrhea 5 yeast infections
How many people die from antibiotic resistance?
More than 2.8 million antibiotic-resistant infections occur in the United States each year, and more than 35,000 people die as a result. Antibiotics can save lives, but any time antibiotics are used, they can cause side effects and contribute to the development of antibiotic resistance.
What is the most urgent threat to the public's health?
Antibiotic resistance is one of the most urgent threats to the public’s health. Antibiotic resistance happens when germs, like bacteria and fungi, develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow.
Why is it important to improve the way we take antibiotics?
Helping healthcare professionals improve the way they prescribe antibiotics, and improving the way we take antibiotics, helps keep us healthy now, helps fight antibiotic resistance, and ensures that these life-saving drugs will be available for future generations.
What are the side effects of taking antibiotics?
Common side effects of antibiotics can include: rash. dizziness. nausea. diarrhea. yeast infections.
Do you need antibiotics for sinus infections?
Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. Antibiotics aren’t needed for many sinus infections and some ear infections. Antibiotics can save lives, and when a patient needs antibiotics, the benefits usually outweigh the risks ...
Why are antibiotics important?
Since their introduction, they have made a major contribution to the world's health. Different bacteria cause different diseases. One antibiotic may only work against one type of bacteria, or a few types. This means that different antibiotics are needed for the treatment of the range of bacterial diseases.
What are some medicines that treat non-communicable diseases?
Antibiotics. Different types of medicines are available to treat many different communicable and non-communicable diseases. Some medicines only treat the symptoms and others cure the disease by killing the pathogens. Many non-communicable diseases can be managed long-term with medicines. Painkillers are chemicals that relieve ...
How to test for resistance to antibiotics?
Bacteria can be tested for resistance to specific antibiotics. Bacteria are spread on an agar plate to make a 'bacterial lawn'. Paper discs soaked in antibiotic are placed on the agar and then incubated. After several days there are clear areas around the discs containing antibiotics which can kill that strain of bacteria. There are no clear areas around discs containing antibiotics that the bacteria are resistant to.
How does antibiotic resistance work?
Antibiotic resistance has now become a common problem. All populations have variation, and resistance of bacteria to an antibiotic can be brought about by just one mutation in a single gene. As bacteria reproduce by binary fission, the number of bacteria with this mutation can increase very quickly. The non-resistant bacteria are destroyed by the antibiotics, which removes competition. With no competition for space and food, the resistant genetic variant can spread quickly.
Why can't we stop bacteria from mutating?
We cannot stop bacteria mutating because it is a natural process that takes place in all populations of organisms. However, we can make it more difficult for resistant bacteria to spread.
How to measure the effectiveness of an antibiotic?
The effectiveness of each antibiotic can be measured by calculating the area of each clear zone around each disc:
Where do medicines come from?
Humans have used medicines for centuries. Most have come from plants and fungi, but increasingly they are being synthesised with chemical reactions.

Economic Impact
- Without antibiotics infectious diseases have devastating consequences for people and economies. For example, one study evaluated historical trends in Staphylococcus aureus infection rate, economic burden, and mortality in U.S. hospitals.22 The authors determined that in 2003, the total economic burden of S. aureus infection was estimated to be $14.5 billion for all inpatient h…
Antibiotic Resistance
- Antibiotic resistance (or antimicrobial resistance, AMR) is a global problem. Unlike almost every other class of drug, antibiotics drive their own obsolescence by selecting for antibiotic-resistant bacteria. Infections caused by antibiotic-resistant bacteria extract a significant public health and economic burden on healthcare systems. The Centers for Disease Control and Prevention (CDC…
