How are drug efflux pumps spread among virulent bacterial strains?

Question

Quizplus · Accepted Answer

Drug efflux pumps are often spread among bacteria through plasmids, which can be transmitted horizontally among different bacterial strains. This allows virulent strains to acquire resistance to antibiotics and other drugs more easily, which can make them more difficult to control and treat. While other mechanisms, such as conjugation or transduction, may also play a role in the spread of drug efflux pumps, plasmid transfer is likely the most common way for these pumps to be disseminated among different bacterial populations.
