Question: could bacteriophages be used to combat bacterial diseases

Answer: Yes, Phage therapy or viral phage therapy is the therapeutic use of bacteriophages to treat pathogenic bacterial infections. Phage therapy has many potential applications in human medicine as well as dentistry, veterinary science, and agriculture. If the target host of a phage therapy treatment is not an animal, the term ``biocontrol'' (as in phage-mediated biocontrol of bacteria) is usually employed, rather than ``phage therapy''.
