According to Figure 27.22, "The rise of antibiotic resistance," which statement accurately describes the timeline of antibiotic resistance?

  • A: Penicillin resistance was first observed before its medical usage began.
  • B: Resistance to Methicillin was observed more than 10 years after its medical usage started.
  • C: Among the antibiotics shown, Daptomycin had one of the shortest gaps between the start of medical usage and the observation of resistance.
  • D: Erythromycin resistance was observed earlier than its medical usage began.

Explanation

Figure 27.22 illustrates that for Daptomycin, medical usage began around 2000, and resistance was observed relatively soon after, around 2005. Compared to older antibiotics like Penicillin or Tetracycline, which had longer periods between usage start and resistance observation, Daptomycin shows a notably shorter interval, indicating a rapid development of resistance.
