Antibiotic resistance as selection notes
Antibiotic resistance occurs when bacteria evolve and become immune to the effects of medications designed to kill them. This phenomenon poses a significant challenge to public health and medical treatments.

Termen in deze set(13)
What is antibiotic resistance?
The ability of bacteria to withstand the effects of antibiotics that once killed them.
True or false: All bacteria are harmful.
False, because many bacteria are beneficial and essential for human health.
What causes antibiotic resistance?
Overuse and misuse of antibiotics, genetic mutations, and horizontal gene transfer among bacteria.
Difference between natural selection and artificial selection
Natural selection occurs in nature, while artificial selection is driven by human choices.
Fill in the blank: Antibiotic resistance can lead to __________ infections.
difficult-to-treat or untreatable infections.
What is horizontal gene transfer?
The process where bacteria exchange genetic material, contributing to resistance.
True or false: All antibiotics are equally effective against all bacteria.
False, because different antibiotics target specific bacteria.
Question: Why is antibiotic misuse a problem?
It accelerates the development of resistance in bacteria.
What role do mutations play in antibiotic resistance?
Mutations can lead to changes in bacterial genes that provide survival advantages.
What are superbugs?
Bacteria that are resistant to multiple antibiotics, making them difficult to treat.
Question: How can we reduce antibiotic resistance?
By using antibiotics responsibly and completing prescribed courses.
Comparison: Antibiotic resistance vs. viral resistance
Antibiotic resistance pertains to bacteria; viral resistance usually refers to antiviral drugs.
Fill in the blank: __________ bacteria can make infections harder to treat.
Resistant
