Antibiotic Resistant Bacteria
Bacteria can evolve rapidly because they reproduce at a fast rate, leading to antibiotic resistance.
Why should you always finish a course of antibiotics?
What is Antibiotic Resistant Bacteria?
"Antibiotic resistance occurs when bacteria change in response to the use of these medicines, making them harder to treat."
How many times does the cell divide during meiosis?
Why is understanding the human genome important for modern medicine?
Which group belongs to the domain Archaea rather than true bacteria?
If both parents are heterozygous (Bb) for a recessive trait (b), what is the probability their child will express the trait?
Bacterial Evolution
Mutations of bacterial pathogens produce new strains.
Some strains might be resistant to antibiotics, and so they are not killed.
The resistant strain survives and reproduces, so the population of the resistant strain increases.
Example: MRSA is a strain of bacteria that is resistant to many antibiotics.
To reduce the rate of development of resistant strains, doctors should not prescribe antibiotics inappropriately and patients should finish the full course.
Want to improve faster?
The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
