Recent studies have demonstrated that gut microbiota development influences infants' health and subsequent host physiology. However, the factors shaping the development of the microbiota remain poorly understood, and the mechanisms through which these factors affect gut metabolite profiles have not been extensively investigated. Here we analyse gut microbiota development of 27 infants during th...

Recently, gut-dwelling bifidobacteria from chimpanzees, which are phylogenetically close to humans and have feeding habits similar to humans, have been frequently investigated. Given this, we speculated that like humans, chimpanzees would have a unique diversity of bifidobacteria. We herein describe a taxonomically novel member of bifidobacteria isolated from fecal samples of captive chimpanzee...

Fifty bifidobacteria strains were isolated from fecal samples of allergic and age matched healthy infants. Allergic infants were found to have an adult type Bifidobacterium flora with high levels of Bifidobacterium adolescentis. Healthy infants had a typical infant Bifidobacterium flora with high levels of Bifidobacterium bifidum. These isolates were tested for their adhesive properties to huma...

The aim of the present work was to compare the efficacies and levels of selectivity of different culture-dependent and -independent methods for analyzing bifidobacteria in human stool samples. The three different culture media used here significantly differed from each other, particularly with regard to the recovery of Bifidobacterium adolescentis. Bifidobacterium medium failed to recover B. ad...

Forty-one strains of Bifidobacterium and Lactobacillus were tested for their ability to induce the proliferation of murine splenocytes using the MTT assay. The tested bifidobacteria induced the apparent proliferation of the murine splenocytes in a strain-dependent manner, while non of the tested lactobacilli showed any mitogenic activity. The bifidobacteria from allergic infants stimulated the ...

Bifidobacteria are common commensals of the mammalian gastrointestinal tract. Previous studies have suggested that a bifidobacterial myosin cross reactive antigen (MCRA) protein plays a role in bacterial stress tolerance, while this protein has also been linked to the biosynthesis of conjugated linoleic acid (CLA) in bifidobacteria. In order to increase our understanding on the role of MCRA in ...

Background Inulin-type fructans have already been studied with respect to their stimulation of bifidobacteria and butyrateproducing colon bacteria, such as Anaerostipes caccae and Roseburia spp. However, much less is known about their effects on other butyrate-producing colon bacteria, such as Butyricicoccus pullicaecorum, Eubacterium spp. and Faecalibacterium prausnitzii and the interactions o...

TPY agar supplemented with mupirocin (100 mg/liter) and glacial acetic acid (1 ml/liter) was effective in the enumeration of bifidobacteria in animal (11 species) fecal or intestinal samples. On the other hand, less than 50% of isolates from pig feces were identified as Bifidobacterium sp. using this medium. Subsequently TPY agar modified by the addition of mupirocin (100 mg/liter), glacial ace...

Mounting evidence elucidates the impact of gut microbiota on maintenance host’s physical and psychological conditions. The can produce its effects through neural, endocrine, immune pathways. Specific members, such as lactobacilli bifidobacteria, have shown unique abilities to affect mental health, hence, they are called psychobiotics. Several studies, both rodents humans, confirmed role Bifidob...
