So Schizophrinia should be curable by clearing the gut bacteria? Sounds like something we already would have known if it was the case. Don’t strong antibiotics clear the gut? And isn’t the microbiome changed within days of traveling to a new country?

A gut cleared of bacteria is not a healthy one. The microbes are necessary, and the genetic makeup and relative populations of microbes have some powerful consequences for a person's health. Fecal transplants are an effective treatment for a number of things.

...”if those things are gut related illnesses “

Finished your sentence.

You're right, of course it is limited to gut-related things.

Probably not. I elaborated more in another comment, but Schizophrenia is characterized by long-term structural changes to the brain. Clearing the gut bacteria is unlikely to reverse those changes.

But as a preventative measure it could be interesting. If this theory is correct, there could be people out there who never developed schizophrenia because they did a course of Cipro at the right time and nuked their dysfunctional gut biome. We would have no way of knowing.
