    Bifidobacterium adolescentis are normal inhabitants of healthy human and animal intestinal tracts. Colonization of B. adolescentisin the gut occurs immediately after birth. Their population in the gut tends to maintain relative stability until late adulthood, where factors such as diet, stress, and antibiotics causes it to decline(2). This species ...

    The genome of Bifidobacterium adolescentis averages 2.1 Mbp in length. Its form is either an elongated, thin irregular rod-, Y- or V-shape. B. adolescentiscontains one circular chromosome. B. adolescentis has 2,089,645 nucleotides, including 1,631 protein-encoding genes and 69 RNA genes (2). G-C content ranges from 42-67% (3), with an average range...

    B. adolescentis is a gram-positive organism, containing one cell membrane, and is not mobile (2,4). Each species of bifidobacteria contain different components in their cell walls; B. adolescentis' cell wall is made made primarily of murein, containing Lys- or Orn-D-Asp within its peptide chains. Its polysaccharide components include glucose and ga...

    Bifidobacteria colonize and reside in the gastrointestinal tracts of humans as well as most mammals. Before birth, human fetuses are microbe-free, and thus do not contain in bacteria within their digestive tracts. However, almost immediately after birth, bacteria begin to colonize in the newborn's intestinal tract, forming the intestinal microflora...

    B. adolescentissynthesizes various B vitamins that are beneficial to the nutritional health of the host organism. Vitamins that are synthesized included thiamin(B1), pyridoxine(B6), folic acid(B9), nicotine, cyanocobalamin(B12), ascorbic acid(Vitamin C), biotin, and riboflavin (4). Also, bifidobacteria contain phytase activity, enabling the dephosp...

    1. Bifidobacterium adolescentis as a producer of folate in the colon: testing various strains of Bifidobacterium revealed their ability to produce folate. Experiments analyzing cultured samples of feces showed that the addition of B. adolescentismay increase the folate concentration in a colonic environment. Results provided positive insight into t...

  3. Bifidobacterium Adolescentis In humans, Bifidobacterium adolescentis has recently been identified as an inducer of Th17 cells, with a mechanism that is distinct from that triggered by segmented filamentous bacterium [63].

  4. They reported that Bifidobacterium lactis DSM 10140 showed the highest level of oxalate degradation at 61%, Bifidobacterium longum MB 282 degraded 35.2% of oxalate, and Bifidobacterium adolescentis MB 238 showed 57% degradation. The oxalate-degrading ability of certain Bifidobacterium species was also strain-specific.
