effect of soy isoflavones on growth of representative bacterial species from the human gut.the present work aimed to assess the susceptibility of dominant and representative bacterial populations from the human gut to isoflavones and their metabolites. to do so, the minimum inhibitory concentration (mic) of isoflavone glycosides, isoflavone aglycones, and equol to 37 bacterial strains was determined by broth microdilution. additionally, for 10 representative strains, growth curves, growth rate (μ), and optical density (od600 nm) of the cultures at 24 h were also determined. mics of da ...201728698467
early gut mycobiota and mother-offspring transfer.the fungi in the gastrointestinal tract, the gut mycobiota, are now recognised as a significant part of the gut microbiota, and they may be important to human health. in contrast to the adult gut mycobiota, the establishment of the early gut mycobiota has never been described, and there is little knowledge about the fungal transfer from mother to offspring.201728837002
administration of two probiotic strains during early childhood does not affect the endogenous gut microbiota composition despite probiotic proliferation.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 ...201728818050
the impact of storage conditions on the stability of lactobacillus rhamnosus gg and bifidobacterium animalis subsp. lactis bb12 in human milk.human milk is the optimal source of complete nutrition for neonates and it also guides the development of infant gut microbiota. importantly, human milk can be supplemented with probiotics to complement the health benefits of breastfeeding. storage of human milk for limited periods of time is often unavoidable, but little is known about the effect of different storage conditions (temperature) on the viability of the added probiotics. therefore, in this study, we evaluated how different storage c ...201728753043

probiotic lactobacillus strains stimulate the inflammatory response and activate human macrophages.lactobacilli have been shown to promote health functions. in this study, we analyzed the mechanism by which four different strains of probiotics affected innate immunity, such as regulation of ros, cytokines, phagocytosis, bactericidal activity, signaling by nf-κb pp65, and tlr2 activation. the production of ros was dependent on the concentration and species of lactobacillus. the results obtained from the tested strains (lactobacillus rhamnosus gg, l. rhamnosus klsd, l. helveticus imau70129, and ...201728758133
arabinoxylans, inulin and lactobacillus reuteri 1063 repress the adherent-invasive escherichia coli from mucus in a mucosa-comprising gut model.the microbiota that colonises the intestinal mucus may particularly affect human health given its proximity to the epithelium. for instance, the presence of the adherent-invasive escherichia coli (aiec) in this mucosal microbiota has been correlated with crohn's disease. using short-term screening assays and a novel long-term dynamic gut model, which comprises a simulated mucosal environment (m-shime), we investigated how (potential) pro- and prebiotics may repress colonisation of aiec from mucu ...201628721250
crystallization and x-ray diffraction analysis of spae, a basal pilus protein from the gut-adapted lactobacillus rhamnosus gg.spae is the predicted basal pilin subunit in the sortase-dependent spafed pilus from the gut-adapted and commensal lactobacillus rhamnosus gg. thus far, structural characterization of the cell-wall-anchoring basal pilins has remained difficult and has been limited to only a few examples from pathogenic genera and species. to gain a further structural understanding of the molecular mechanisms that are involved in the anchoring and assembly of sortase-dependent pili in less harmful bacteria, l. rh ...201728580919

lactobacillus rhamnosus atcc 7469 exopolysaccharides synergizes with low level ionizing radiation to modulate signaling molecular targets in colorectal carcinogenesis in rats.combination therapy that targets cellular signaling pathway represents an alternative therapy for the treatment of colon cancer (crc). the present study was therefore aimed to investigate the probable interaction of lactobacillus rhamnosus atcc 7469 exopolysaccharides (eps) with low level ionizing γ radiation (γ-r) exposure against dimethylhydrazine (dmh)- induced colorectal carcinogenesis in rats. colon cancer was induced with 20mg dmh/kg bw. rats received daily by gastric gavage 100mg eps/kg b ...201728554134
the role of microbiota and immunobiotics in granulopoiesis of immunocompromised hosts.the number of granulocytes is maintained by a regulated balance between granulopoiesis in the bone marrow and clearance and destruction in peripheral tissues. granulopoiesis plays a fundamental role in the innate immune response. therefore, factors affecting the normal granulopoiesis lead to alterations in innate defenses and reduce the resistance against infections. in this study, we give a description on recent advances regarding the molecular and cellular events that regulate steady-state and ...201728533775
a novel millet-based probiotic fermented food for the developing world.probiotic yogurt, comprised of a fiti sachet containing lactobacillus rhamnosus gr-1 and streptococcus thermophilus c106, has been used in the developing world, notably africa, to alleviate malnutrition and disease. in sub-saharan african countries, fermentation of cereals such as millet, is culturally significant. the aim of this study was to investigate the fermentation capability of millet when one gram of the fiti sachet consortium was added. an increase of 1.8 and 1.4 log cfu/ml was observe ...201728531168
enhancement of antioxidative and intestinal anti-inflammatory activities of glycated milk casein after fermentation with lactobacillus rhamnosus 4b15.in this study, we investigated the glycoproteomics of glycated milk casein (gmc) and gmc fermented by lactobacillus rhamnosus 4b15 (fgmc) and determined their biological implications. there was a significant increase in the antioxidative and anti-inflammatory activities of gmc with galactose, which were higher than those of gmc with glucose (gmc-glc). furthermore, the fermentation of gmc by l. rhamnosus 4b15 synergistically enhanced the above activities compared to those of unfermented gmc. espe ...201728510450
lactobacillus rhamnosus crl1505 nasal administration improves recovery of t-cell mediated immunity against pneumococcal infection in malnourished mice.immunobiotic lactic acid bacteria have become an interesting alternative for the prevention of respiratory infections. previously, we demonstrated that the nasal administration of lactobacillus rhamnosus crl1505, during repletion of malnourished mice, resulted in diminished susceptibility to the challenge with the respiratory pathogen streptococcus pneumoniae. considering the known alterations induced by malnutrition on t lymphocytes and the importance of this cell population on the protection a ...201728504568
genotypic and phenotypic diversity of lactobacillus rhamnosus clinical isolates, their comparison with strain gg and their recognition by complement system.lactobacillus rhamnosus strains are ubiquitous in fermented foods, and in the human body where they are commensals naturally present in the normal microbiota composition of gut, vagina and skin. however, in some cases, lactobacillus spp. have been implicated in bacteremia. the aim of the study was to examine the genomic and immunological properties of 16 clinical blood isolates of l. rhamnosus and to compare them to the well-studied l. rhamnosus probiotic strain gg. blood cultures from bacteremi ...201728493885
fermentation of protopanaxadiol type ginsenosides (pd) with probiotic bifidobacterium lactis and lactobacillus rhamnosus.ginsenosides are believed to be the principal components behind the pharmacological actions of ginseng, and their bioactive properties are closely related to the type, position, and number of sugar moieties attached to the aglycone; thus, modification of the sugar chains may markedly change their biological activities. in this study, major protopanaxadiol type ginsenosides (pd) rb1, rc, and rb2 were isolated from panax ginseng and were transformed using two probiotic strains namely bifidobacteri ...201728478490
