The age-specific microbiome of children with milk, egg, and peanut allergy.

Background: Immune regulation by gut microbiota is affected by dysbiosis and may precede food allergy onset. Prior studies lacked comparisons stratified by age and clinical phenotype.

Objective: To assess the microbiome of children with food allergy (<3 years, 3-18 years) compared with similar aged children without food allergy.
