&gt; Nope, the problem is you need to identify the specific Bacteria that&#x27;s causing a problem before you can use a bacteriophage to fight it.<p>Uh, that&#x27;s not actually an issue as I understand it. The treatment, as I understand it, works by starting with a sample of infected tissue from the infected person. The bacteriophages are then grown starting from a few different kinds of starters, but the process I read about starts with a broad spectrum of bacteriophages. As long as a bacteriophage is close enough to being able to attack the desired bacteria, it some percentage of the bacteriophages will mutate into the exact bacteriophages you want. Since the available food for the bacteriophages is the bacteria you want to kill, the bacteriophage specific to that bacteria grows exponentially until there are enough bacteriophages. At this point the solution contains a large number of bacteriophages specifically bred to kill the bacteria in question. The solution is reintroduced into the infected tissue, where it eats most of the bacteria.<p>&gt; Antibiotics are much simpler to use.<p>Chanting healing spells is simpler to use than antibiotics and in a few decades time it will be equally effective.
