A public health agency is developing a campaign to slow the spread of antibiotic resistance in the general population. Which of the following messages would be the most effective at addressing a key driver of this phenomenon?

Evaluating a Clinical Decision

A patient who has taken multiple courses of antibiotics for various infections over several years finds that a particular antibiotic is no longer effective for their latest bacterial infection. This is because the patient's body has developed a resistance to the antibiotic.

Arrange the following events to illustrate the process by which a bacterial population develops widespread resistance to an antibiotic.

A bacterial population is exposed to an antibiotic. The vast majority of the bacteria are killed, but a small number possess a pre-existing genetic mutation that allows them to survive. What is the most likely long-term consequence for this bacterial population if the antibiotic exposure is repeated over time?

Match each scenario with the principle of antibiotic resistance it best illustrates.

The widespread, and often unnecessary, use of antibiotics in medicine and agriculture creates a strong ____ ____, which eliminates susceptible bacteria and allows resistant strains to thrive and multiply.
