Antibiotic Resistant Bacteria Flashcards
How do bacteria develop antibiotic resistance?
Bacteria develop random mutations in their DNA, leading to changes in their characteristics, such as antibiotic resistance.
Why is the ability to resist antibiotics advantageous for bacteria?
Antibiotic resistance provides bacteria with a survival advantage, allowing them to survive and reproduce more effectively, increasing the population size of the resistant strain
Why are antibiotic-resistant strains a concern for public health?
-there are limited treatment options available
-there will be potential for infections to spread more easily.
What is MRSA, and why is it considered a ‘superbug’?
MRSA (Methicillin-resistant Staphylococcus aureus) is a common ‘superbug’ that is difficult to treat. It can cause severe infections, particularly in hospital settings, and can be fatal if it enters the bloodstream.
What has been the trend in the death rate from infectious bacterial diseases in the last few decades?
The death rate from infectious bacterial diseases, such as pneumonia, has fallen dramatically.
What factors contribute to the worsening problem of antibiotic resistance?
Overuse and inappropriate use of antibiotics, including prescribing them for non-serious conditions or viral infections, contribute to antibiotic resistance.
Why is it important for doctors to prescribe antibiotics only when necessary?
to avoid contributing to antibiotic resistance.
Why is it important for patients to complete the full course of antibiotics prescribed by a doctor?
Completing the full course of antibiotics ensures that all bacteria are destroyed, preventing the development of antibiotic-resistant strains.
How does the use of antibiotics in farming contribute to antibiotic resistance in humans?
Antibiotics given to animals in farming can lead to the development of antibiotic-resistant bacteria, which can spread to humans through meat preparation and consumption.
What efforts are being made to address antibiotic resistance, and what challenges do they face?
Drug companies are working on developing new antibiotics to address antibiotic resistance, but progress is slow and costly, making it challenging to keep up with the demand for new drugs as resistant strains continue to develop and spread.
