Long-term colonization exceeding six years from early infancy of Bifidobacterium longum subsp. longum in human gut.

ABSTRACT:

Background

The importance of the gut microbiota at the early stage of life and their longitudinal effect on host health have recently been well investigated. In particular, Bifidobacterium longum subsp. longum, a common component of infant gut microbiota, appears in the gut shortly after birth and can be detected there throughout an individual's lifespan. However, it remains unclear whether this species colonizes in the gut over the long term from early infancy. Here, we investigated the long-term colonization of B. longum subsp. longum by comparing the genotypes of isolates obtained at different time points from individual subjects. Strains were isolated over time from the feces of 12 subjects followed from early infancy (the first six months of life) up to childhood (approximatel
