Click to flip
What is selective pressure in the context of antibiotic resistance?
Click to flip
The environmental pressure that favors the survival of resistant strains.
Click to flip
Why is the development of new antibiotics important?
Click to flip
To overcome resistant bacteria with limited treatment options.
Click to flip
What is one example of a bacterial mechanism of resistance?
Click to flip
Production of enzymes that degrade the antibiotic, such as beta-lactamase.
Click to flip
What ethical considerations exist in antimicrobial stewardship?
Click to flip
