Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Most of probiotic bacteria currently available market belong to genera Lactobacillus and Bifidobacterium, specific health-promoting activities, such as treatment diarrhea or amelioration gastrointestinal discomfort, have been attributed them. In order be able survive transit transiently colonize our gut, these must counteract deleterious action bile salts, main components bile....

Background: Human milk is a complex fluid comprised of myriad substances, with one the most abundant substances being group carbohydrates referred to as human oligosaccharides (HMOs). There has been some evidence that HMO profiles differ in populations, but few studies have rigorously explored this variability. Objectives: We tested hypothesis diverse populations healthy women. Next, we examined relations between and maternal anthropometric reproductive indexes indirectly whether differences...

Abstract Gamma aminobutyric acid (GABA) is the principal inhibitory neurotransmitter playing a key role in anxiety and depression disorders mammals. Recent studies revealed that members of gut microbiota are able to produce GABA modulating gut–brain axis response. Among human microbiota, bifidobacteria well known establish many metabolic physiologic interactions with host. In this study, we performed genome analyses more than 1,000 bifidobacterial strains publicly available revealing...

Background Microbial communities in human milk and those feces from breastfed infants vary within across populations. However, few researchers have conducted cross-cultural comparisons between populations, little is known about whether certain "core" taxa occur normally or populations variation microbiome related to infant fecal microbiome. The purpose of this study was describe microbiomes produced by relatively healthy women living at diverse international sites compare these the their...

The microbial populations of the human intestinal tract and their relationship to specific diseases have been extensively studied during last decade. However, characterization bile microbiota as a whole has hampered by difficulties in accessing biological samples lack adequate methodologies assess molecular studies. Although few reports described biliary some hepatobiliary diseases, healthy individuals not described. With this mind, goal present study was generate fundamental knowledge on...

Abstract Starch, glycogen, maltooligosaccharides, and other α-1,4- α-1,6-linked glucose carbohydrates, exclusive of resistant starch, are collectively termed "dietary starch". This nutritionally important fraction is increasingly measured for use in diet formulation animals as it can have positive or negative effects on animal performance health by affecting energy supply, glycemic index, formation fermentation products gut microbes. AOAC Method 920.40 that was used measuring dietary starch...

Human milk provides a very wide range of nutrients and bioactive components, including immune factors, human oligosaccharides, commensal microbiota. These factors are essential for interconnected processes immunity programming the development normal infant gastrointestinal microbiome. Newborn protection mostly relies on maternal provided through milk. However, studies dealing with an in-depth profiling different compounds present in assessment their natural variation healthy women from...

Pectin is a group of structurally diverse dietary fibers, very abundant in agri-food waste and by-products such as those generated during apple cider manufacturing. In recent years, pectin pectinoligosaccharides have demonstrated good fermentation properties prominent health promoting traits, particularly ameliorating certain inflammatory conditions. previous investigations pomace derived from production monovarietal Asturian ciders was to represent source with varied structural...

Abstract Human milk represents a source of bacteria for the initial establishment oral (and gut) microbiomes in breastfed infant, however, origin human remains largely unknown. While some evidence points towards possible endogenous enteromammary route, other authors have suggested that are contaminants from skin or infant mouth. In this work 16S rRNA sequencing and bacterial culturing isolation was performed to analyze microbiota on maternal precolostrum samples, collected pregnant women...

Abstract Background The microorganisms that inhabit food processing environments (FPE) can strongly influence the associated quality and safety. In particular, possibility FPE may act as a reservoir of antibiotic-resistant microorganisms, hotspot for transmission antibiotic resistance genes (ARGs) is concern in meat plants. Here, we monitor microbial succession resistome dynamics relating to through detailed analysis newly opened pork cutting plant over 1.5 years activity. Results We...

Previously published data from our group and others demonstrate that human milk oligosaccharide (HMOs), as well infant fecal microbial profiles, vary by geography. However, little is known about the geographical variation of other milk-borne factors, such lactose protein, associations among these factors community structures in feces. Here, we characterized contrasted concentrations lactose, HMOs, examined their with microbiomes samples collected 11 geographically diverse sites. Although...
