The diversity of intestinal bacteria protects against allergies
A recent study suggested that the great diversity and differences in the intestinal bacteria that protects kids from allergies compared to the existence of single type of bacteria. Study, the comparison between the intestinal bacteria in children with allergic and Tabiein.
One of the hypotheses suggests that the immune system during childhood has a small number of bacteria, which explains the increasing sensitivities of children, however, researchers can not prove the hypothesis in practice.
The researchers said that children receive the beneficial intestinal bacteria from the surrounding environment, and perhaps children are not exposed to enough bacteria, which are necessary for the maturation of the immune system.
Researchers previously believed that the diversity of bacteria in the gut is important for the occurrence of allergic reactions in infants. Now you can find a link and a clear view of the modern techniques based on DNA.
Were analyzed stool samples from 40 children, 20 of them are infected with eczema and antibodies to certain foods, and 20 others who were not suffering from any of these cases.
Using DNA techniques, the researchers could determine the sequence of DNA that have been linked to data to determine the type of bacteria that were present in the samples.
Results showed that diversity was more pronounced in healthy children at the age of the month, compared with children, who suffered from allergies subsequently, as the diversity in some types of bacteria was important. Where the presence of bacteria, called Proteobacteria which are gram negative Tet linked to protection from allergies, as they commonly exist in children who grew up on farms. Also showed that the bacteria Bacillus It helps to resist infections.
The components of the bacteria in the intestines during the first few weeks of life is showing clear signs of growth of the immune system. And the disappearance of important stimuli of different types of bacteria, the body's possible to over-reaction against the anti-non-harmful to the environment such as food. And that the risk of asthma for children in the school-age children living with these sensitivities more than 5 to 6 times.
