In 2005, scientists discovered a strain of fruit flies that was resistant to the pesticide DDT. Although pesticide resistance can sometimes decrease the overall fitness of an organism, these flies did not exhibit reduced fitness. In fact, the flies thrived in the absence of the pesticide.
Bacteria Y is a harmful strain of a usually helpful bacteria that lives on human skin. Antibiotic X is usually effective against bacteria Y. Suppose a situation similar to the fruit fly's resistance to DDT developed between bacteria Y and antibiotic X. Which course of treatment would MOST likely help a patient suffering from a disease caused by the newly developed strain of bacteria Y?
