Which of the following statements is false about antibiotics?
Antibiotics are not capable of curing any disease. Antibiotics are those substances that destroy or inhibit the growth of micro-organisms, particularly disease producing bacteria and fungi. The term antibiotic was introduced by Waksman in 1942. Common antibiotics include penicillins, streptomycin and tetracyclines.
Which of the following is true regarding the resistance of bacteria to antibiotics quizlet?
Which of the following statements is TRUE regarding antibiotic resistance in bacteria? All bacteria are naturally resistant to all antibiotics. Some individuals in bacterial populations naturally have the mutations that lead to resistance. Exposure to antibiotic caused the mutations that lead to resistance.
Which are true of antibiotic resistance?
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. Infections caused by antibiotic – resistant germs are difficult, and sometimes impossible, to treat.
Which of the following processes in bacteria can be interrupted by antibiotics quizlet?
Antibiotics can interrupt cell wall and membrane formation, ribosome function, and DNA replication, transcription and translation within bacteria.
Which one of the following statement is correct about effect of antibiotic on virus?
Antibiotics kill only bacteria. They don’t work against viruses. Most common colds and sore throats are caused by viruses.
What are antibiotics produced by?
Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi.
What are two reasons that antibiotic resistance has been able to evolve in bacteria so quickly?
Bacteria can evolve quickly because they reproduce at a fast rate. Mutations in the DNA of bacteria can produce new characteristics. A random mutation might cause some bacteria to become resistant to certain antibiotics, such as penicillin.
Why does antibiotic resistance occur quizlet?
Why is antibiotic resistance becoming more common? Because of overuse and inappropriate use of antibiotics. Because taking the full course makes sure all the bacteria are destroyed which means there are none left to mutate and develop antibiotic resistant strains.
What has led to the evolution of antibiotic resistant bacteria quizlet?
evolution of antibiotic – resistant bacteria? The presence of an antibiotic in an environment leads to the selection of those individuals that are most resistant to it. some insects have a gene that makes them resistant to the pesticide. the frequency of resistant insects in the population increases.
How do you treat antibiotic resistance?
To help fight antibiotic resistance and protect yourself against infection:
- 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.
- Finish your pills.
- Get vaccinated.
- Stay safe in the hospital.
How do you develop antibiotic resistance?
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.
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 bacteria is antibiotic resistant?
Bacteria resistant to antibiotics
- methicillin- resistant Staphylococcus aureus (MRSA)
- vancomycin- resistant Enterococcus (VRE)
- multi- drug – resistant Mycobacterium tuberculosis (MDR-TB)
- carbapenem- resistant Enterobacteriaceae (CRE) gut bacteria.
Which is more fit antibiotic resistant bacteria or antibiotic sensitive bacteria?
Antibiotic – resistant bacteria are more fit for an environment where antibiotics are used frequently. The ability to resist antibiotics may cause bacteria to be less fit in other environments where antibiotics are not present. Bacteria that are sensitive to antibiotics have a reproductive advantage in all environments.
Is the development of antibiotic resistance in bacteria an example of evolution?
Antibiotic resistance is a stunning example of evolution by natural selection. Bacteria with traits that allow them to survive the onslaught of drugs can thrive, re-ignite infections, and launch to new hosts on a cough. Evolution generates a medical arms race.
