Bacteriophages Selectively Infect Bacterial Cells

question 44

Multiple Choice

Bacteriophages selectively infect bacterial cells. How might they be used as a therapeutic treatment in humans?

• A) Phages can carry genes into cells which will genetically modify the host cells to prevent infection.
• B) Phages can be used to stimulate human immune cells to attack and kill bacterial cells.
• C) Bacteriophages can be used to genetically engineer bacterial cells making them more susceptible to drugs.
• D) Humans suffering from infections with antibiotic resistant bacteria can be treated with phages, which will infect and lyse the bacterial cells, leaving human cells unaffected.
