Policy Brief 10

Antibiotic resistance is a challenge that calls for good science as well as ingenuity. Although we will always need new antibiotics, there are alternative therapeutic approaches worth considering. One example is bacteriophage therapy. Bacteriophages—or "phages"—exist in abundance in nature, including in and on the human body. Phages are viruses that infect bacteria and use the bacterial cell’s genetic apparatus to produce more phages. In the process, they kill their host. By harnessing phages’ natural ability to destroy bacteria, infections can be cleared.
