Quick Answer: Which Of The Following Statements Helps To Explain How Bacteria Can Become Antibiotic-resistant?

0 Comments

How does bacteria become resistant to antibiotics?

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.

Which of the following contributes to the evolution of antibiotic resistant bacteria?

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

What are 3 ways a bacterial cell can have a resistance to antibiotics?

Resistant bacteria continue to multiple, even when exposed to antibiotics; Horizontal Gene Transfer – Antibiotic – resistant genetic material is transferred between different bacteria cells. This can happen in three different ways: transformation, transduction or conjugation.

How do bacteria become resistant to antibiotics quizlet?

How do bacteria become resistant to antibiotics? Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

How do you treat antibiotic resistance?

To help fight antibiotic resistance and protect yourself against infection:

  1. Don’t take antibiotics unless you’re certain you need them. An estimated 30% of the millions of prescriptions written each year are not needed.
  2. Finish your pills.
  3. Get vaccinated.
  4. Stay safe in the hospital.

How common is antibiotic resistance?

Antibiotic resistance is one of the biggest public health challenges of our time. Each year in the U.S., at least 2.8 million people get an antibiotic – resistant infection, and more than 35,000 people die.

What are antibiotic resistance genes?

Antibiotic resistance occurs due to changes, or mutations?, in the DNA? of the bacteria, or the acquisition of antibiotic resistance genes ? from other bacterial species through horizontal gene transfer. These changes enable the bacteria to survive the effects of antibiotics designed to kill them.

What are some other examples of antibiotic resistant bacteria?

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.

How can we prevent antibiotic resistance?

There are many ways that drug- resistant infections can be prevented: immunization, safe food preparation, handwashing, and using antibiotics as directed and only when necessary. In addition, preventing infections also prevents the spread of resistant bacteria.

What are the four ways a bacteria can become resistant to an antibiotic?

The three fundamental mechanisms of antimicrobial resistance are (1) enzymatic degradation of antibacterial drugs, (2) alteration of bacterial proteins that are antimicrobial targets, and (3) changes in membrane permeability to antibiotics.

Is antibiotic resistance permanent?

Dutch research has shown that the development of permanent resistance by bacteria and fungi against antibiotics cannot be prevented in the longer-term. The only solution is to reduce the dependence on antibiotics by using these less.

How do you treat resistant bacteria?

If you have an infection that is antibiotic- resistant, your healthcare provider may or may not have other treatment options. Taking unneeded antibiotics promotes the growth of resistant bacteria. Practice good hygiene. It helps prevent the spread of infections that are resistant to antibiotics.

What factors contribute to antibiotic resistance quizlet?

What four factors contribute to the development of antibiotic resistance?

  • Adhesion factors.
  • Evasive factors.
  • Invasive factors.
  • Toxins.

What does antibiotic resistance mean quizlet?

STUDY. What is Antibiotic Resistance? -Ability of bacteria or other microbes to resist the effects of an antibiotic. -Natural selection gives resistant organisms an adaptive advantage.

How does antibiotic resistance arise How do hospitals and feedlots contribute to this phenomenon?

Answer Expert Verified Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Hospitals ‘ overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.
