Complex oligosaccharides from human milk (HMO) possess an antimicrobial activity and can promote the growth of bifidobacteria such as Bifidobacterium bifidum and Bifidobacterium longum subsp. infantis. In addition, fermentation of carbohydrates by bifidobacteria can result in the production of metabolites presenting an antivirulence effect on several pathogenic bacteria. Whey is rich in complex...
Portions of the 16S rRNA from closely related species of the genus Bifidobacterium that are found in the human intestinal microflora were sequenced in order to design species-specific oligonucleotide probes. Five oligonucleotide probes ranging from 16 to 19 bases in length and complementary to 16S rRNA sequences from Bifidobacterium adolescentis, B. bifidum, B. breve, B. infantis, and B. longum...
Bifidobacteria colonize the gut of various mammals, including humans, where they may metabolize complex, diet-, and host-derived carbohydrates. The glycan-associated metabolic features encoded by bifidobacteria are believed to be strongly influenced by cross-feeding activities due to the co-existence of strains with different glycan-degrading properties. In this study, we observed an enhanced g...
SLC26A3, or downregulated in adenoma (DRA), plays a major role in mediating Cl(-) absorption in the mammalian intestine. Disturbances in DRA function and expression have been implicated in intestinal disorders such as congenital Cl(-) diarrhea and gut inflammation. We previously showed that an increase in DRA function and expression by Lactobacillus acidophilus and its culture supernatant (CS) ...
Soy-based foods are rich in high quality proteins, essential amino acids, minerals, vitamins etc. thus they provide a range of health benefits. In this study, growth and α-galactosidase activity of bifidobacteria (Bifidobacterium lactis Bb-12, B. longum Bb-46, B. bifidum B3.2, B. bifidum B7.1 and B. breve B9.14) were investigated. All tested bifidobacteria strains showed αgalactosidase activity...
In this study sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) profiles were analysed and differences were confirmed by a unweighted pair group method with arithmetic average (UPGMA) analysis between bifidobacterial species, such as B. infanis ATCC1567, B. bifidum Bb-12, B. longum KN29, B. catenulatum KD14, and B. animalis BI30. Two dimensional electrophoresis separation pr...
The Lactobacillus and Bifidobacterium microflora of the human intestine: composition and succession.
Lactobacillus and bifidobacterial cultures are increasingly used as probiotics in pharmaceuticals and in foods. The selection of strains is performed often for technological rather than for microecological reasons. Detailed reports about species and strains composition of these microorganisms in the intestinal microflora of man are rare. Our investigations were performed with samples originatin...
16SrDNA-targeted genus- and species-specific PCR primers have been developed and used for the identification and detection of bifidobacteria. These primers cover all of the described species that inhabit the human gut, or occur in dairy products. Identification of cultured bifidobacteria using PCR primer pairs is rapid and accurate, being based on nucleic acid sequences. Detection of bifidobact...
The aim of the study was to compare the compositions of the fecal microbiotas of infants fed goat milk formula to those of infants fed cow milk formula or breast milk as the gold standard. Pyrosequencing of 16S rRNA gene sequences was used in the analysis of the microbiotas in stool samples collected from 90 Australian babies (30 in each group) at 2 months of age. Beta-diversity analysis of tot...
Recent advances in gut microbial flora research have shown the health benefits of probiotic bacterial strains on small and large intestines. These strains, particularly Bifidobacterium, offer advantages, including obesity, atopic diseases, inflammatory bowel intestinal cancers human body. However, food components, additives, processing-related factors can an impact survival. As a result, adding...
