00:06 Intestinal microbiota are all the microorganisms which live mainly in the small intestine and the colon.
00:12 There are about 100 trillion microorganisms, bacteria, parasites, viruses and fungi living on the walls of the intestine.
00:20 Scientific research has shown that these intestinal flora play a role in the healthy functioning of the digestive, metabolic, neurological and immune systems.
00:30 This ecosystem is considered a separate organ, unique to each individual, like the genetic code.
00:36 The richer the microbiota, the more likely a person will be in good health.
00:40 The microbiota of a healthy individual comprise 160 species of bacteria.
00:45 They form at birth during contact with the vaginal and fecal flora during the delivery.
00:50 Afterwards, the microbiota evolve depending on diet, genetics, hygiene and medical treatments.
00:56 Antibiotics, for example, can reduce the quality and quantity of microbiota for several days.
01:02 Intestinal flora play a role in digestion, with fermentation, the absorption of nutrients and the synthesis of certain vitamins.
01:09 Microbiota react on the intestinal immune system, essential to the barrier role of the intestinal wall.
01:15 In the case of inflammatory diseases of the intestine, treatment can involve the transplanting of excrement from healthy donors.
01:23 It is estimated that microbiota could have an influence on neurodegenerative diseases such as Parkinson's or neuropsychiatric conditions such as depression or bipolar disorder.
