Document Summary
Bad bacteria release toxins into bloodstream enters brain. Nervous system vagus nerve (nerve connecting gut and brain: more diversity of bacteria = healthier. Good bacteria: some produce gaba (neurotransmitters) Women drinking probiotic yogurt had less negative emotional status. We are developing autoimmune issues and allergies (body attacks itself) Gut has its own nervous and immune system: bacteria in gut produce chemicals that affect vagus nerve, gaba, neurotransmitter, depresses things (stops nerve activities) Associated with calm feeling: some bacteria produce this, you want diversity in your microbiomes, when less diverse, you are more susceptible to invasion of pathogens. Using organisms and dna manipulation to create/alter other organisms/life forms. By manipulating dna, you can make gmo food. In e. coli: there is a genome (all genes in cell, and the recombinant dna that was introduced to cell, e. coli will replicate and replicate both genome and recombinant dna.
