Your intestines has about 39 trillion microorganisms in it. And yes I said trillion. We call this collection of organisms the microbiome and it consists of mostly bacteria, but also viruses and fungi. Collectively it weighs about 3 pounds which is about the same weight as your brain.

We feed these organisms and they produce chemicals that we need. They send messages to the brain through the vagus nerve.

Several factors determine whether or not your have good vs. bad bacteria:
Diet
Medications
Age
Sleep
Activity level
