Effect of Fructooligosaccharide Metabolism on Chicken Colonization by an Extra-Intestinal Pathogenic Escherichia coli Strain
Extra-intestinal pathogenic Escherichia coli (ExPEC) strains cause many diseases in humans and animals. While remaining asymptomatic, they can colonize the intestine for subsequent extra-intestinal infection and dissemination in the environment. We have previously identified the fos locus, a gene cluster within a pathogenicity island of the avian ExPEC strain BEN2908, involved in the metabolism...
متن کاملInfluence of Fructooligosaccharide on Pharmacokinetics of Isoflavones in Postmenopausal Women
The objective of the present paper was to determine the influence of fructooligosaccharide (FOS) on the pharmacokinetics of isoflavones in healthy postmenopausal women. The study was a fixed-sequence, two-phase, crossover study. Twelve subjects received a single oral dose of 300 mL of a soy beverage. Blood samples were collected before the dose and at 0.5, 1, 2, 4, 6, 8, 10, 12, 24, and 32 h af...
متن کاملIdentification of prebiotic fructooligosaccharide metabolism in Lactobacillus plantarum WCFS1 through microarrays.
Short-chain fructooligosaccharides (scFOS) and other prebiotics are used to selectively stimulate the growth and activity of lactobacilli and bifidobacteria in the colon. However, there is little information on the mechanisms whereby prebiotics exert their specific effects upon such microorganisms. To study the genomic basis of scFOS metabolism in Lactobacillus plantarum WCFS1, two-color microa...
متن کاملKinetics of butyrate, acetate, and hydrogen metabolism in a thermophilic, anaerobic, butyrate-degrading triculture.
Kinetics of butyrate, acetate, and hydrogen metabolism were determined with butyrate-limited, chemostat-grown tricultures of a thermophilic butyrate-utilizing bacterium together with Methanobacterium thermoautotrophicum and the TAM organism, a thermophilic acetate-utilizing methanogenic rod. Kinetic parameters were determined from progress curves fitted to the integrated form of the Michaelis-M...
متن کاملNutrient Metabolism—Research Communication Megasphaera elsdenii JCM1772 Normalizes Hyperlactate Production in the Large Intestine of Fructooligosaccharide-Fed Rats by Stimulating Butyrate Production
Hyperlactate production is related to disorders of the large intestine such as inflammatory bowel diseases. Lactate, an intermediate in hindgut fermentation, is metabolized to SCFA. Megasphaera elsdenii can convert lactate to butyrate, a physiologically important organic acid for the hindgut mucosa. This experiment was conducted to determine whether M. elsdenii normalizes hyperlactate productio...
