    I may be wrong, but I’ve read that phage therapy is nothing new. Russia and other countries have been doing it for decades. The reason that we (in the US) are just looking at it now is because the pharmaceutical companies have manipulated the FDA squash it. You can’t patent a phage and it’s in direct competition with their products.

    What happens if phages gets so immune that they start hunting human cells like once they are injected in the body and after they kill all the bacteria there will be no food other than human cells so will evolve over time in a such a way that they start feeding on human cells?????

    Could bacteriophage kill diseases or cancer? If so, why dont we look at this as an alternate medicine for curing HIV or Cancers? If its as easy as giving the phage antibiotics to kill find the bacteria that is immune to it. Then I would think it would be as easy as giving the Phage HIV or the Cancer cell that is killing the body?

    Uh what. After the antibiotics/antibodies invade us and die, they only experienced the antibiotics once. If the same bacteria invades, they will die to the antibodies. Thus, they only get antibiotics once.

    It is a a nice alternate but would it really be a good idea in the long run?? lets say when the amount of bad bacteria will be reduced and battle for existence will fall upon those phases. isn't there a risk of them evolving to attack human cells ?
