28. Antimicrobial Drugs

Which statement about antibiotic resistance is true?

The process of bacteria temporarily fusing to pass plasmids between them is called:

Vancomycin-resistant Enterococcus (VRE) can cause dangerous infections and is most often spread in hospital settings. VRE is resistant to vancomycin due to a change in the amino acid sequence in the peptidoglycan precursor molecule, leading to a reduction in the binding efficiency of vancomycin. This mechanism could be described as:

Which of the following resistance mechanisms do you think would be LEAST likely to develop in response to penicillin-type antibiotics in a Gram-positive bacterium?

Which of the following resistance mechanisms do you think would NOT result in a lower concentration of the drug inside a cell?

How does the use of an antibiotic against viral infections increase the prevalence of resistance to that antibiotic?

Which answer best describes why the use of antibiotics in agriculture is a significant concern for the spread of antibiotic resistance in human diseases?
