5.Looking at the table above, predict what will happen if a new antibiotic to the food poisoning bacteria Campylobacter jejuni is developed and prescribed heavily by physicians beginning in 2012.

• Campylobacter jejuni will be effectively treated for the next 2–3 decades.
• Campylobacter jejuni will be effectively treated for the next 2–5 years.
• The new antibiotic will make all former antibiotics for treating Campylobacter jejuni

obsolete.

• B and C

MSC: Applied

6.Considering the table above, which of the following statements is likely true?

• Antibiotic resistance will not evolve to newer antibiotics. 3 / 4

• Eventually, pharmaceutical companies will need to come up with new categories of

antibiotics that work in ways not yet conceived.

• Physicians will need to work in locally and globally coordinated ways to assure that newly

developed antibiotics are not overprescribed.

industries in which of the following ways?

tolerated doses of new antibiotics.
