A collaborative research group consisting of the Mucosal System Research Team at the RIKEN Center for Integrative Medical Sciences and the Center for Preventive Medicine, Chiba University, has revealed that a gut microbiota enterotype dominated by Bifidobacterium genus in one-month-old children is associated with lower food allergen sensitization and a lower risk of developing food allergies in the future.

The collaborative research group used gut microbiota data from two birth cohort studies in Japan to show that having the most mature enterotype with a predominance of Bifidobacterium at one month of age is associated with a lower rate of egg white allergen sensitization and the development of food allergies in the future.
