Antibiotic-resistant Infections FAQ

What are antibiotic resistant bacteria?

Antimicrobial resistant bacteria are bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic. Most infection-causing bacteria can become resistant to at least some antibiotics. Bacteria that are resistant to many antibiotics are known as multi-resistant organisms (MRO).

What is antibiotic resistance?

Antibiotic resistance is when bacteria change to resist antibiotics that used to effectively treat them. This makes certain bacterial infections difficult to treat. Overuse and misuse of antibiotics cause antibiotic resistance. You can help combat this global health problem by taking these drugs only when your provider says they’re necessary.

Do bacteria become resistant to antibiotics?

It’s not the individual who becomes resistant to antimicrobial medication, rather, resistance is a property of the micro-organism, and almost every species of bacteria has acquired some resistance and become less responsive to antibiotic treatment since the 1940s. If you are unlucky enough to catch an antibiotic-resistant infection, you:

What is antibiotic resistance & why is it important?

Antimicrobial resistance (AMR) occurs when germs (bacteria, virus, or fungus) that cause infections resist the effects of the medicines used to treat them. These resistant bacteria can spread and may infect people or animals. They are harder to treat than non-resistant bacteria. Why are antibiotics important? What is antibiotic resistance?

What happens if a patient is resistant to an antibiotic?

Resistance to even one antibiotic can mean serious problems. For example: Antimicrobial-resistant infections that require the use of second- and third-line treatments can harm patients by causing serious side effects, such as organ failure, and prolong care and recovery, sometimes for months

What happens if you have an antibiotic-resistant infection?

If it takes longer for providers to find a medication that will treat an antibiotic-resistant infection, the outcome can be more serious. Antibiotic resistance is dangerous because it reduces treatment options for people who are sick. It may also delay effective treatment. As a result, you may face:
