Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.Jul 31, 2020

Full Answer

What are the dangers of antibiotic resistance?

  • Antibiotic resistance happens when bacteria develop a defense against one, or multiple antibiotic drugs.
  • Antibiotic resistance is dangerous because it can make infections, like UTIs, harder to treat.
  • The overuse of antibiotic drugs in agriculture and medicine has is the main cause of antibiotic-resistant bacteria.

Why you should care about antibiotic resistance?

Antibiotic resistance jeopardizes advancements in modern health care that we have come to rely on, such as joint replacements, organ transplants, and cancer therapy. These procedures have a significant risk of infection, and patients won’t be able to receive them if effective antibiotics are not available.

Should I be concerned about antibiotic resistance?

While antibiotics should be used to treat bacterial infections, they are not effective against viral infections like the common cold, most sore throats, and the flu. Widespread use of antibiotics promotes the spread of antibiotic resistance. Smart use of antibiotics is the key to controlling the spread of resistance.

Why should we care about antibiotic resistance?

Why should we care about antibiotic resistance? Antibiotic resistance is a global challenge for human and animal health. The more antibiotic resistance spreads, the less effective antibiotics become for fighting disease.

What is antibiotic resistance and why does it matter?

Antimicrobial 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.

What is the best explanation for antibiotic resistance?

Antimicrobial resistance is accelerated when the presence of antibiotics and antifungals pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antimicrobial-resistant germs survive and multiply.

What happens if you become antibiotic-resistant?

When bacteria become resistant, the original antibiotic can no longer kill them. These germs can grow and spread. They can cause infections that are hard to treat. Sometimes they can even spread the resistance to other bacteria that they meet.

What are examples of antibiotic resistance?

Examples of bacteria that are resistant to antibiotics include methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Enterococcus, and multidrug-resistant Mycobacterium tuberculosis (MDR-TB), which is resistant to two tuberculosis drugs, isoniazid and rifampicin.

What causes bacteria to become resistant to antibiotics?

There are two main ways that bacterial cells can acquire antibiotic resistance. One is through mutations that occur in the DNA of the cell during replication. The other way that bacteria acquire resistance is through horizontal gene transfer.

How does antibiotic resistance occur naturally?

Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed biochemical “pumps” that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic.

What is antibiotic resistance gene definition?

ARGs are mobile genetic elements that can pass between microorganisms via horizontal gene transfer, even from dead to living cell.

How does antibiotic resistance affect humans?

The number of bacteria that are resistant to antibiotics is increasing. The danger of antibiotic resistance is that treatable illnesses, such as pneumonia, tuberculosis, or minor infections could become incurable. This would put a greater economic and emotional burden on families and on our healthcare system.

What is the purpose of the WAAW?

Held annually since 2015, WAAW is a global campaign that aims to increase awareness of antimicrobial resistance worldwide and to encourage best practices among the general public, health workers and policy makers to avoid the further emergence and spread of drug-resistant infections . Antimicrobials are critical tools in helping to fight diseases in humans, animals and plants. They include antibiotics, antivirals, antifungals and antiprotozoa. WAAW takes place every year from 18 to 24 November. The slogan has previously been, “Antibiotics: Handle with Care” but changed to “Antimicrobials: Handle with Care” in 2020 to reflect the broadening scope of drug resistant infections.

Why are antibiotics harder to treat?

A growing number of infections – such as pneumonia, tuberculosis, gonorrhoea, and salmonellosis – are becoming harder to treat as the antibiotics used to treat them become less effective. Antibiotic resistance leads to longer hospital stays, higher medical costs and increased mortality.
