(Submitter supplied) We investigated the capabilities of bifidobacteria to reduce the cholesterol level in the media, which clearly evidenced a high ratio of assimilation of this molecule by specific bifidobacterial strains including Bifidobacterium bifidum PRL2010. The transcriptomics of PRL2010 cells cultivated in the presence of cholesterol evidenced a significant higher expression of carriers as well as reductase encoding genes

Eleven groups of five conventional female 8-wk-old BALB/c mice taking a standard polysaccharide-rich Chow diet were administered a single daily dose of 109 CFU of either B. bifidum PRL2010, B. breve 12L , B. adolescentis 22L , B. longum subsp. infantis ATCC15697, or bifidobacterial couples, i.e., PRL2010-12L, PRL2010-22L, PRL2010-ATCC15696, 12L-22L, 12L-ATCC15697, 22L-ATCC15697, or a combination of all bifidobacterial strains. more...

(Submitter supplied) Bifidobacteria constitute commensal bacteria that commonly inhabit the mammalian gastro intestinal tract. The gut commensal Bifidobacterium breve UCC2003 was previously shown to utilise a variety of plant/diet-derived carbohydrates, including cellodextrin, starch and galactan. In the current study, we investigated the ability of this strain to utilize (parts of) a host-derived source of carbohydrate, namely the mucin glycoprotein. more...

(Submitter supplied) Bifidobacteria constitute a specific group of commensal bacteria which inhabit the gastrointestinal tract of humans and other mammals. Bifidobacterium breve UCC2003 has previously been shown to utilise several plant-derived carbohydrates that include cellodextrins, starch and galactan. In the current study, we investigate the ability of this strain to utilise the mucin- and human milk oligosaccharide (HMO)-derived carbohydrate, sialic acid. more...

(Submitter supplied) In this study, we investigated the transcriptome of Bifidobacterium bifidum PRL2010 during in vitro growth by micro array technology. When B. bifidum PRL2010 was grown in liquid broth, 425 of the 1644 PRL2010 genes represented on the array were expressed in at least one of the three investigated growth phases, i.e., lag-, exponential and stationary phase. These transcriptional analyses identified a core in vitro transcriptome encompassing 150 genes, which resulted expressed in all phases. more...

(Submitter supplied) A bacterial nursling stool isolate, Bifidobacterium breve UCC2003, encodes two putative sulfatases. The sulfated monosaccharide N-acetylglucosamine-6-sulfate (GlcNAc-6-S) was shown to support growth of B. breve UCC2003, while three other tested sulfated monosaccharides, N-acetylglucosamine-3-sulfate, N-acetylgalactosamine-3-sulfate and N-acetylgalactosamine-6-sulfate, did not. Using a combination of transcriptomic and functional genomic approaches, a gene cluster, designated ats2, was shown to be specifically required for GlcNAc-6-S metabolism. more...

(Submitter supplied) Bifidobacteria represents one of the dominant group of microorganisms colonizing the intestine of infants. However, the genetic determinants supporting the establishment and the interaction with the human hosts are still largely unknown. Most commensal bacteria interacting with eukaryotic hosts express adhesive molecules on their surfaces that modulate interaction with host cell receptors or with soluble macromolecules. more...
