Document Summary
Treat sewage, break down garbage, keeps us at a certain weight, make food, inflammation process & allergies, in. Lower intestine synthesize vitamins to allow breakdown, 8 million expressed by our body, n/s/p/c/o2 recycled by bacteria. Turn inorganic molecules into organic compounds ie. nucleic acids. Make oxygen; break down waste; food production (wine, cheese, bread); drug preparation (insulin, penicillin) Natural microbial flora provides protection against more virulent microbes. When the normal composition of microbes is thrown out of balance, the body"s natural defenses become exhausted/overwhelmed and the human host can experience a myriad of negative effects like obesity, inflammation, allergy and infection. Microbe-host equilibrium natural evolution of a microbe operates on a spreading capacity, not on it"s ability to cause a disease. Tb (stays in system for 30 years before killing em) & hiv (24 years): less aggressive, take longer to kill. Ebola virus/sars: extremely aggressive, kills a lot of ppl (90% of infected ppl quickly)
