In this study, the V3 and V4 regions of the 16S rRNA gene from metagenomic DNA were sequenced to identify differences in microbial diversity in raw milk of Saanen and Guanzhong goats from the Guanzhong area of China. The results showed that Proteobacteria was the predominant phylum, accounting for 71.31% of all phyla identified in milk from the 2 breeds, and Enterobacter was the predominant genus (24.69%) within the microbial community. Microbial alpha diversity from Saanen goat milk was significantly higher than that of Guanzhong goat milk based on bioinformatic analysis of indices of Chao1, Shannon, Simpson, observed species, and the abundance-based coverage estimator...

The gut microbiota is altered in liver diseases, and several probiotics have been shown to reduce the degree of liver damage. We hypothesized that oral administration of specific Bifidobacterium strains isolated from healthy guts could attenuate liver injury. Five strains were tested in this study. Acute liver injury was induced by D-galactosamine after pretreating Sprague-Dawley rats with the Bifidobacterium strains, and liver function, liver and ileum histology, plasma cytokines, bacterial translocation and the gut microbiome were assessed...

BACKGROUND AND AIM: Recent studies have reported beneficial effects of specific probiotics on obesity. However, the difference in the anti-obesity effects of probiotics as single species and dual species is still uncertain. Therefore, we aimed to compare the efficacy of single and dual species of bacteria on markers of obesity in high-fat diet-induced obese rats. METHODS AND RESULTS: A total of 40 male Sprague-Dawley rats were assigned to one of five groups of varying diets as follows: standard diet, high fat diet (HFD), HFD supplemented with Lactobacillus casei strain Shirota, HFD supplemented with Bifidobacterium longum and HFD supplemented with a mixture of these two bacterial species...

A marked elevation in the abundance of Bifidobacterium was found in the cecum of rats that were fed a high-fat diet supplemented with an Amano protease preparation (derived from Aspergillus oryzae). The protease preparation contains several digestive enzymes, including acid protease (AcP), alkaline protease, and amylase. We hypothesized that the elevation in the abundance of Bifidobacterium by Amano protease preparation is associated with the digestive enzymes involved in the protease preparation. To test this hypothesis, this study was conducted to investigate if such bifidogenic effect is because of the AcP...

Bifidobacterium longum W11 is a commercialized probiotic that has an exopolysaccharide (EPS) layer covering its surface which could play a role in the beneficial properties attributed to the strain; thus, we have carried out chemical and biological analyses of this polymer. The eps cluster putatively involved in the polymer synthesis presented a unique structural organization not previously reported in bifidobacteria. B. longum W11 produced a complex polysaccharide blend with the main component composed of glucose and galactose...

BACKGROUND: Probiotics are increasingly applied to prevent and treat a range of infectious, immune related and gastrointestinal diseases. Despite this, the mechanisms behind the putative effects of probiotics are poorly understood. One of the suggested modes of probiotic action is modulation of the endogenous gut microbiota, however probiotic intervention studies in adults have failed to show significant effects on gut microbiota composition. The gut microbiota of young children is known to be unstable and more responsive to external factors than that of adults...

Human gut symbiont bifidobacteria possess carbohydrate-degrading enzymes that act on the O-linked glycans of intestinal mucins to utilize those carbohydrates as carbon sources. However, our knowledge about mucin type O-glycan degradation by bifidobacteria remains fragmentary, especially regarding how they decompose sulfated glycans, which are abundantly found in mucin sugar-chains. Here, we examined the abilities of several Bifidobacterium strains to degrade a sulfated glycan substrate and identified a 6-sulfo-β-d-N-acetylglucosaminidase, also termed sulfoglycosidase, encoded by bbhII from Bifidobacterium bifidum JCM 7004...

A total of 57 infants hospitalized with rotavirus disease were included in this study. The children were randomly divided into the study's two treatment groups: three days of the oral administration of (i) a probiotics formula containing both Bifidobacterium longum BORI and Lactobacillus acidophilus AD031 (N = 28); or (ii) a placebo (probiotic-free skim milk, N = 29) and the standard therapy for diarrhea. There were no differences in age, sex, or blood characteristics between the two groups. When the 57 cases completed the protocol, the duration of the patients' diarrhea was significantly shorter in the probiotics group (4...

OBJECTIVE: The brain-gut-microbiota axis has been put forward as a new paradigm in neuroscience, which may be of relevance to mental illness. The mechanisms of signal transmission in the brain-gut-microbiota axis are complex and involve bidirectional communications which enables gut microbes to communicate with the brain, and the brain to communicate with the microbes. This review assesses the potential usefulness and limitations of the paradigm. METHODS: A selective literature review was conducted to evaluate the current knowledge in clinical and pre-clinical brain-gut-microbiota interactions as related to psychiatric disorders...

Beneficial bacteria are becoming ever more popular gene delivery method for hypoxia- tumor targeting in vivo. In this study we investigated the therapeutic effect of new recombinant Bifidobacterium breve strain expressing IL-24 gene (B.breve-IL24) on head and neck tumor xenograft in mice. Briefly, B.breve transformants were obtained through electro-transformation. Bacteria-tumor targeting ability were analyzed in vivo over different time points (1, 3 and 7 days post- bacteria injection). Furthermore, the therapeutic effect of bacteria on tumor cells in vivo were analyzed as follows: 30 Balb/c nude mice bearing subcutaneous tumor were randomly divided in three groups (Drug group, GFP group and Saline group)...

Hou-Po-Da-Huang Tang (HPDHT) was used for the treatment of intestinal tract diseases in China. However, the underlying mechanisms via the intestinal bacteria remain largely unclear. Therefore, the aim of this study was to evaluate the metabolism of HPDHT by the human intestinal bacteria and its modulating effect on the intestinal bacteria. As a result, a total of 34 compounds were identified in HPDHT and transformed HPDHT (T-HPDHT). Among them, 12 metabolites were proved to be transformed by human intestinal bacteria...

An extracellular layer of exopolysaccharides (EPS) covers the surface of some Bifidobacterium animalis subsp. lactis strains, which could be of relevance for its probiotic performance. In order to understand the functional characteristics of B. animalis subsp. lactis, two isogenic strains that differ in their EPS-producing phenotype, due to a single mutation in the gene Balat_1410, were studied. By means of a double crossover recombination strategy, successfully used for the first time in bifidobacteria, Balat_1410 in the type strain B...

Probiotics, as dietary supplements, transmit their major effects through the regulation of gut microbiota. According to a previous study, one possible mechanism of Lactobacillus casei CCFM419 protection against diabetes may involve gut flora. To test this hypothesis, high fat and streptozotocin-induced C57BL/6J mice were fed L. casei CCFM419 at 10(8), 10(9), and 10(10) colony forming units (CFU). Compared to untreated mice, 10(9) CFU of L. casei CCFM419 attenuated several symptoms of diabetes, including fasting blood glucose, postprandial blood glucose, glucose intolerance, and insulin resistance...

BACKGROUND & AIMS: Interactions between commensal microbes and the immune system are tightly regulated and maintain intestinal homeostasis, but little is known about these interactions in humans. We investigated responses of human CD4(+) T cells to the intestinal microbiota. We measured the abundance of T cells in circulation and intestinal tissues that respond to intestinal microbes and determined their clonal diversity. We also assessed their functional phenotypes and effects on intestinal resident cell populations, and studied alterations in microbe-reactive T cells in patients with chronic intestinal inflammation...

Human milk contains high concentrations of nondigestible complex oligosaccharides (human milk oligosaccharides; HMO) that reach the colon and are subsequently fermented by the infant gut microbiota. Using a high-throughput, low-volume growth determination, we evaluated the ability of 12 lactobacilli and 12 bifidobacteria strains, including several commercial probiotics, to ferment HMO and their constituent monomers. Of the 24 strains tested, only Bifidobacterium longum ssp. infantis ATCC 15697 and Bifidobacterium infantis M-63 were able to ferment 3'-sialyllactose, 6'-sialyllactose, 2'-fucosyllactose, and 3'-fucosyllactose...
