Experiments carried out in two European groups, which include over 1,000 participants, show that two types of bacteria are not at risk from people who have experienced experiments. suffering from depression.
The human disease may be closely related to the brain (referral)
Many people are not familiar with, but the human brain, as well as working, is closely tied to the chon, and the incredible amount of micro-organisms that have created it; human cause of the permanent home.
In recent years, a number of investigations have shown, with increasing strength, strong communication between the neuronal, endocrine and immune systems and microbiota.
One of the most interesting and controversial things is the relationship between intestinal microbial metabolism and mental health and controversial in microbiomes research. So far, this relationship has been in small groups of animals. But now, research published in the Nature Microbiology magazine, is proven in a large group of people that this relationship is suited.
"This is the first correct test of how the chemicals in microprint could affect mood in humans," said John Cryan, a neurocient expert at the Scottish College, The University of Cork in Ireland, who has been one of the earliest candidates for microbial ties. -rerebral.

To find this link, Jeroen Raes, a biologist at the Belgian Roman Catholic University, accompanied by 14 co-workers from a number of European universities to explore this situation. For this, They looked closely with 1054 Belgians they were employed to evaluate "normal" midwife. Some of the group, 173 in total, were convinced that they were heavy or achieved well in the quality of life inspection.
What did the studies do? compare the presence of four types of bacteria False diseases among partners that reported a higher quality of life and have been diagnosed with depression, the most common mental disorder in industrial societies.
In order to prove that the density of the variation that was different on the biofuism of the participants, the factors that were measured as scientists are age, sex or antidepressants, which are all that affecting its microbioma.
"Four deducted taxes have been identified particularly in dementia / disordered partners," said the researchers. These four types of bacteria were found in a good number of people with high quality of life.
"The bacteria that do Faecalibacterium butyrate and Coprococcus they were tied regularly with indicators of a higher quality of life. along with Dialister, Coprococcus spp. They also run out in depression, even after trying to correct the effects of antioxidants, "reading their work.
The researchers found that poor people had an increase in the bacteria that were involved in Crohn's disease (a disease that appears to be normal).
The research, John Cryan to Science, said "greatly builds the field where it is" by minor surveys of humans affected by animals or experiments.
