Ciprofloxacin is given as an antibiotic to healthy livestock to promote efficient weight gain. Strains of the bacterium Campylobacter jejuni naturally colonize the digestive tracts of livestocks, and the C. jejuni can be transferred to people through the handling and consumption of contaminated meat. People infected with C. jejuni are also treated with ciprofloxacin. Which of the following is the most likely consequence of adding ciprofloxacin to animal feed?
(A)Naturally occurring strains of C. jejuni will reproduce more rapidly in the digestive tracts of livestock, reducing the risk of foodborne illnesses in people
(B)Ciprofloxacin-resistant strains of C. jejuni will have a selective advantage in the digestive tracts of livestock, increasing the risk of serious infections in people.
(C)Ciprofloxacin-sensitive strains of C. jejuni will be consumed in meat that contains a chemical that inhibits bacterial growth, reducing the risk of food poisoning in people.
(D)Actively growing strains of C. jejuni will metabolize the nutrients in meat produced by livestock operations, increasing the risk of protein deficiencies in people.
