Microbiomic analysis of the bifidobacterial population in the human distal gut
Abstract
One of the most complex microbial ecosystems is represented by the microbiota of the human gastrointestinal tract (GIT). Although this microbial consortium has been recognized to have a crucial effect on human health, its precise composition is still not fully established. Among the GIT bacteria, bifidobacteria represent an important commensal group whose presence is often associated with health-promoting effects. In this work, we assessed the complexity of the human intestinal bifidobacterial population by analysing the diversity of several 16S rRNA gene-based libraries. These analyses showed the presence of novel bifidobacterial phylotypes, which had not been found earlier and may thus represent novel taxa within the genus Bifidobacterium.

In the human gut the most commonly found species of Bifidobacterium genus include B. adolescentis, B. angulatum, B. bifidum, B. breve, B. catenulatum, B. dentium, B. longum, B. pseudocatenulatum, and B. pseudolongum, whereas B. animalis subsp. lactis is the species most often included in functional foods and food supplements.

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.
