They could probably make a targeted antibiotic, but gut bacteria are something not very well understood yet, and it's a highly complex ecosystem (some would say more complex than our own cells) that differs significantly from person to person. they have done studies though to see if doing a guy bacteria transplant from a healthy person to an obese person would change their weight, I believe there wasn't any difference found for weight loss but that there was some hope in using it as a treatment for diabetes. I'd have to look it up. This particular study though I wonder if it was the calorie restriction, the weight loss or the content of the diet that caused the changes to happen.
