Research has found that the cause of atopic dermatitis in infants is linked to specific bacteria in the mother's gut and a lack of dietary fiber intake. Korea University announced on the 29th that Professor Kim Hee-nam's research team from the Department of Biomedical Sciences has identified this fact for the first time in the world.

Until now, research on atopic dermatitis has focused solely on skin tissue. However, recently, the imbalance in the gut microbiome has been highlighted as a major cause. In a 2016 study, Professor Kim's research team confirmed that certain species of the major gut bacterium, Faecalibacterium, are abnormally present in children with atopic dermatitis and may be involved in the development of the condition.

In this study, Professor Kim's research team demonstrated through mouse experiments that Faecalibacterium can actually induce skin symptoms. When the bacteria were injected into pregnant mice, a systemic inflammatory response occurred, and more severe systemic inflammation was observed in the newborn mice.

The results of this study were published online in the world-renowned medical science journal 'Microbiome'.
