Abstract

GOAL: The aim of this study was to characterize the composition of the intestinal microbiota in healthy centenarians in comparison with younger adults, considering both quantitative and qualitative aspects of gut community structure. BACKGROUND: The gut microbiota plays an essential role in human health. Toward seniority, its balance is affected by deep physiological changes. Long-lived people (age >90 y) have unusual features that differ from the younger elderly, so they should be considered separately when analyzing age-related features. However, they have been included in few studies and they have usually been grouped together with the younger elderly. STUDY: The gut microbiota of 14 centenarians and 10 younger adults was analyzed. Cultivable bacteria belonging to the following groups were enumerated: enterobacteriaceae, Enterococcus, Staphylococcus, Lactobacillus, Bifidobacterium, Clostridium, Bacteroides, and yeast. Lactobacilli and Bifidobacteria were further characterized at the species level by pyrosequencing. RESULTS: : In centenarians, we observed a reduction in the quantity of enterobacteriaceae, bifidobacteria, and bacteroides and an increase in clostridia sensu stricto (P<0.05). The number of Lactobacillus and Bifidobacterium species isolated in centenarians and younger adults was similar. The composition of the Lactobacillus subpopulation was quite different between the groups. The presence of Bifidobacterium longum in the gut seems to be a particular feature in centenarians. It is interesting to note that only 1 strain of B. longum was isolated from each centenarian subject. CONCLUSIONS: The gut microbiota of centenarians has particular features that differ from both younger adults and the younger elderly. Further studies would help to understand whether the intestinal microbiota can influence life expectancy and whether the administration of probiotic bacteria could help to extend the longevity of human life.

  • Bifidobacteria numbers and diversity decrease with age.

    “By using different approaches and techniques, it has been observed that bifidobacteria numbers and diversity decrease with age, although the fact that particular bifidobacterial types are more related with the elderly still remains obscure (10–12).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
