If a child is exposed to various types of bacteria in the first years of growth, their risk of allergies later in life will decline. That's the conclusion of researchers from the University of Copenhagen, Denmark, which suggests a new factor in some diseases of modern lifestyle.
Over sensitivity disease, or allergies, now affects 25 percent of the population of Denmark. This number is increasing rapidly in recent decades. Experiments the researchers at the Copenhagen Prospective Studies on Asthma in Childhood (Copsac), University of Copenhagen, there is a possibility may explain the rise in allergy sufferers.
"Our study of more than 400 children showed a direct link between the amount of various bacteria differ in their rectum and the risk of developing allergic diseases when they grow up," says Hans Bisgaard, a consultant at the Gentofte Hospital, Head of Asthma in Children Prospective Studies in Copenhagen and lecturer childhood disease in the Faculty of Health Sciences, University of Copenhagen.
Bisgaard said the reduced diversity of micro organisms in the gut during infancy is associated with increased risk of allergic diseases at school age. "But, if diversity is high, the risk is decreased, and the more diverse variations, the less risk," he said.
He said the way the baby is born should also be considered. "There is a difference if the baby was born normal, which is exposed to bacteria from the rectum for the first time mother, or by operation of exposing the baby to a little bacteria," he said. "Maybe this is the reason why more babies are born via cesarean section suffer from allergies."
In the womb and during the first six months, infants are protected by mother's immune system. Bacteria in infants later taken antibiotics influenced the mother and all types of artificial substances that affect the mother.
Our findings suggest that bacteria that had been considered as the enemy turned out to be a part of healthy living. "It's ironic," says Bisgaard. "I think the mechanism that affects the immune system will affect more than just allergies." *** [SCIENCEDAILY | KORAN TEMPO 3701]
