The graph illustrates how the antibiotic resistance of a bacterium species changed from 2000 to 2016 in one country. Each year, bacteria samples were taken from 48 hospitals. The bacteria were then examined to determine whether they were resistant to five different antibiotics. What conclusion can be drawn from the data shown in the graph?
- AOveruse of ciprofloxacin has caused antibiotic resistance to increase by more than 20% between 2000 and 2016.
- BPercentage resistance to three of the antibiotics was at a peak in 2015.
- CChanges in treatment guidelines have caused resistance to some antibiotics to decrease from 2015 to 2016.
- DThe percentage of resistant bacteria is higher in 2016 than 2000 for all antibiotics.
