A strictly anaerobic bacterium capable of metabolizing sennosides was isolated from human feces and identified as Bifidobacterium sp., named strain SEN. The bacterium hydrolyzed sennosides A and B to sennidins A and B via sennidin A and B 8-monoglucosides, respectively. Among nine species of Bifidobacterium having beta-glucosidase activity, only Bifidobacterium dentium and B. adolescentis metab...

CONTEXT Intestinal flora and anaerobes are frequently implicated in causing infectious necrotizing pancreatitis however Bifidobacterium and Veillonella have rarely been isolated as the causative agents. Bifidobacterium and Veillonella are commensal anaerobes which reside in gastrointestinal tract and help deconjugate bile acids. Bifidobacterium is also frequently used in probiotics. CASE REPO...

Frozen dairy products have characteristics of both yogurt and ice cream and could be the persuasive carriers of probiotics. Functions of the frozen yogurt containing viable bifidobacterial cells are recognized and favored by the people of all ages. We developed a kind of yogurt supplemented by Bifidobacterium species. Firstly, five strains of Bifidobacterium spp. (Bifidobacterium bifidum ATCC 1...

BACKGROUND & AIMS Inulin-type fructans (ITF) prebiotics promote changes in the composition and activity of the gut microbiota. The aim of this study was to determine variations on fecal short chain fatty acids (SCFA) concentration in obese women treated with ITF and to explore associations between Bifidobacterium species, SCFA and host biological markers of metabolism. METHODS Samples were ob...

BACKGROUND The colonic bacterial flora, largely anaerobic, is believed to establish and stabilize in the first 2 y of life. OBJECTIVE This study was undertaken to determine whether the bacterial flora of the colon undergoes further changes (succession) during childhood and adolescence. DESIGN This cross-sectional study examined fecal samples from 130 healthy children and adolescents in the ...

This report investigates the requirement for CO2 for colony formation by Bifidobacterium species in both anoxic and oxic environments. All tested Bifidobacterium species exhibited difficulty in developing colonies in an atmosphere of 100% N2 but developed well when 1% CO2 was present. In the presence of CO2, the oxygen tolerance of the tested species was not improved. In the absence of CO2, onl...

Cocultures of strains from two Bifidobacterium and two Bacteroides species were performed with exopolysaccharides (EPS) previously purified from bifidobacteria, with inulin, or with glucose as the carbon source. Bifidobacterium longum NB667 and Bifidobacterium breve IPLA20004 grew in glucose but showed poor or no growth in complex carbohydrates (inulin, EPS E44, and EPS R1), whereas Bacteroides...

Bifidobacterium species are difficult to identify and may be underreported or not recovered by many laboratories because of their slow growth. We emphasize the importance of the Gram stain in urine samples and the addition of enriched media and enhanced atmosphere over time for urine cultures with pyuria. This is the first report of a Bifidobacterium scardovii recurrent urinary infection in an ...

Epithelial barrier dysfunction has been implicated as one of the major contributors to the pathogenesis of inflammatory bowel disease. The increase in intestinal permeability allows the translocation of luminal antigens across the intestinal epithelium, leading to the exacerbation of colitis. Thus, therapies targeted at specifically restoring tight junction barrier function are thought to have ...
