The babies who live near farm animals have a stronger immune system , according to have proven a team of researchers from the Ohio State University (united States) in a study published in the journal "Frontiers in Immunology".
"good hygiene is important, but from the perspective of our immune systems, a healthy environment robs our immune systems the opportunity to be educated by microbes ", have said the experts, who collected faecal samples from ten babies between six months and one year of age that lived near farms, and of five other children who had no contact with animals.
The samples revealed significant differences, especially a wide variation of microbes and a large amount of beneficial bacteria in the stools of infants that lived in contact with animals, in comparison with those living in cities.
Later, experts explored how the different microbiomes bowel might contribute to the development of the immune system and, for this purpose, they used transplants stools of the infants in the study to colonize the gut of newborn pigs.
Thus, scientists were able to see a connection between the various gut microbes of children who were in contact with animals and developing a more robust of the immune cells, especially of lymphoid and myeloid cells in the intestines.
