ScienceDaily (Dec. 5, 2010) — Atopic dermatitis (also known as atopic eczema) is a chronic and extremely painful inflammation of the skin that frequently occurs in early childhood, generally starting in infancy. Up to 20 percent of all children in industrialized countries are affected, making it one of the most common childhood skin diseases.

Earlier research has already indicated that allergies are less common in children who grow up on farms and whose mothers live on farms during their pregnancy. Exposure to farm animals and bacteria frequently found in farms as well as drinking milk from the dairy offer the immune system protection.

The researchers were able to demonstrate that women who spend their pregnancy in the proximity of farm animals and cats have children with a reduced risk of developing atopic dermatitis in their first two years of life. The research team also identified two genes in these children that are of vital importance for innate immunity and was able to link the expression of these genes to a lower likelihood of a doctor diagnosis of an allergic condition.
