I quoted the article in order to comment:

One company is aiming to treat infections with a different strategy: arming tiny viruses called bacteriophages with Crispr.

I checked it just out: CRISPR is already part of the intra-celluar immun system of baacterias and archaea.

Whereas antibiotics kill bacteria indiscriminately—including the beneficial kind—phages have evolved to be selective in the strains or species of bacteria they target.

So, the phages would not attacke the "good" bacteria within the stomach but the evil ones. Could be a great idea.
