Notes


- During life, the numbers of bifidobacteria decrease from up to 90% of the total colon microbiota in vaginally delivered breast-fed infants to <5% in the colon of adults and they decrease even more in that of elderly.

- Increase in Proteobacteria during aging, which is thought to be a common change in gut microbiome ageing, irrespective of typical elderly or long-living subjects. Furthermore, the relative abundance of Faecalibacterium in the long-living people reduced when compared to the younger group across cohorts.(2)
