Bacteriophages selectively infect bacterial cells. How might they be used as a therapeutic treatment in humans?
A. Bacteriophages can be used to genetically engineer bacterial cells making them more susceptible to drugs. B. Phages can be used to stimulate human immune cells to attack and kill bacterial cells.
