Questions and Answers

How can enzymatic degradation of antibacterial drugs influence antimicrobial resistance?

  • Enhance the effectiveness of antibiotics
  • Have no impact on bacterial resistance
  • Decrease bacterial susceptibility to antibiotics (correct)
  • Increase bacterial susceptibility to antibiotics

    • What is the key difference between acquired and induced resistance?

  • Acquired resistance is permanent, while induced resistance is reversible (correct)
  • Acquired resistance is passed on genetically, while induced resistance is temporary
  • Acquired resistance is developed due to exposure to antibiotics, while induced resistance is innate
  • Acquired resistance is mediated by enzymes, while induced resistance is due to altered bacterial proteins

    • What is the purpose of an antimicrobial susceptibility test?

  • To measure the effectiveness of antibiotics against bacteria (correct)
  • To determine the speed of bacterial growth
  • To detect the presence of bacterial enzymes
  • To identify the type of bacteria present
