Flashcards on Antibiotics and Resistance
Click on the flashcard to see the answer
What are antibiotics?
Medications that fight bacterial infections.
What is antibiotic resistance?
When bacteria develop the ability to survive and grow in the presence of antibiotics.
What causes antibiotic resistance?
Overuse and misuse of antibiotics.
What are the consequences of antibiotic resistance?
Infections become harder to treat and can result in longer illnesses, increased healthcare costs, and higher mortality rates.
How can we prevent antibiotic resistance?
By using antibiotics only when necessary, completing the full course of treatment, and following healthcare professionals' advice.
What are superbugs?
Bacteria that are resistant to multiple antibiotics.
What are the different mechanisms of antibiotic resistance?
Efflux pumps, target modification, enzymatic inactivation, and reduced permeability.
What is MRSA?
Methicillin-resistant Staphylococcus aureus, a type of bacteria that is resistant to many antibiotics.
What is the role of antibiotic stewardship?
Promoting the responsible use of antibiotics to preserve their effectiveness and reduce antibiotic resistance.
Can bacteria transfer antibiotic resistance to each other?
Yes, bacteria can transfer antibiotic resistance genes through horizontal gene transfer.
What are the challenges in developing new antibiotics?
High cost, lengthy development process, and the emergence of resistance to new antibiotics.
What is antibiotic susceptibility testing?
A laboratory technique used to determine which antibiotics are effective against a particular bacterial infection.
What are broad-spectrum antibiotics?
Antibiotics that are effective against a wide range of bacteria.
What is the difference between bactericidal and bacteriostatic antibiotics?
Bactericidal antibiotics kill bacteria, while bacteriostatic antibiotics inhibit their growth.
What is the optimal use of antibiotics?
Using the right antibiotic at the right dose for the right duration.
