How do you explain antibiotic resistance?
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.
What is antibiotic resistance GCSE?
Over time, bacteria can become resistant to certain antibiotics (such as penicillin). This is an example of natural selection. In a large population of bacteria, there may be some that are not affected by an antibiotic. These survive and reproduce – producing more bacteria that are not affected by the antibiotic.
How does antibiotic resistance occur BBC Bitesize?
A random mutation occurs in the DNA of individual bacterial cells. The mutation protects the bacterial cell from the effects of the antibiotic – it becomes antibiotic resistant. Bacteria without the mutation die when the antibiotic is present.
How does bacteria become antibiotic-resistant?
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 do antibiotics work GCSE?
How do antibiotics work? Antibiotics damage the bacterial cells by inhibiting their cellular processes, but do not damage the host cells. They have the ability to cure some bacterial diseases that would have previously killed many people.
How does an antibiotic work BBC Bitesize?
Antibiotics damage the bacterial cells by inhibiting their cellular processes, but do not damage the host cells. They have the ability to cure some bacterial diseases that would have previously killed many people. Since their introduction, they have had a large influence on the world’s health and death rate.
What are the obstacles to understanding the issue of antimicrobial resistance?
One of the major obstacles to understanding the issue of antimicrobial resistance is that the subject material appears abstract and is complex. This video was designed to make the concept of antimicrobial resistance more real and understandable to veterinarians, livestock producers, lawmakers, consumer representatives and other key audiences.
How to reduce antibiotic resistance in hospitals?
Ways to reduce antibiotic resistance 1 Only take antibiotics when necessary. 2 Treat specific bacteria with specific antibiotics. 3 High hospital hygiene levels, including regular hand washing by staff and visitors. 4 Patients who are infected with antibiotic resistant strains of bacteria should be isolated from other patients.
How will the use of antimicrobial drugs change over time?
Over time, the use of antimicrobial drugs will result in the development of resistant strains of bacteria, complicating clinician’s efforts to select the appropriate antimicrobial for treatment. Accordingly, efforts are underway in both veterinary and human medicine to preserve the effectiveness of these drugs.
