Synbiotics, a conjunction between prebiotics and probiotics, have been used in aquaculture for over 10 years. However, the mechanisms of how synbiotics work as growth and immunity promoters are far from being unraveled. Here, we show that a prebiotic as part of a synbiotic is hydrolyzed to mono- or disaccharides as the sole carbon source with diverse mechanisms, thereby increasing biomass and colonization that is established by specific crosstalk between probiotic bacteria and the surface of intestinal epithelial cells of the host...

This study investigates the effectiveness of two types of prebiotics-stachyose and raffinose-which are present in staple food crops that are widely consumed in regions where dietary Fe deficiency is a health concern. The hypothesis is that these prebiotics will improve Fe status, intestinal functionality, and increase health-promoting bacterial populations in vivo (Gallus gallus). By using the intra-amniotic administration procedure, prebiotic treatment solutions were injected in ovo (day 17 of embryonic incubation) with varying concentrations of a 1...

Functional ingredients such as pre- and probiotics are used in aquaculture to improve fish condition, modulating microbiota and promoting a healthy intestinal functioning. They also exert an active effect on the gut associated lymphoid tissue (GALT), stimulating the immune system. However, the molecular underpinnings of pre- and probiotics effect on intestinal mucosa are still unknown. This study investigated the intestinal mucosa transcriptome modulation when fish were fed functional diets and kept at different stocking densities...

Altered gut bacteria and bacterial metabolic pathways are two important factors in initiation and progression of inflammatory bowel disease (IBD). However, efficacy of probiotics in remission of patients with IBD has not been characterized. This study was performed on the studies that specifically assessed the efficacy of probiotics in attaining clinical response on patients with various types of IBD. The efficacy of variant species of probiotics in different conditions and the influence of study quality in outcomes of randomized controlled trials (RCTs) were also assessed...

Major advances have occurred in the knowledge of the pathogenesis of Inflammatory Bowel Disease (IBD) over the last decade, and perhaps the most major, and clinically advantageous of these advances has been the discovery of the microbiome as a key multifaceted component of inflammation. The Gut microbiome is the largest known group of cells in the body, and is now recognised as an organ in its own right. Initial studies looking at a possible role of bacterial manipulation of the immune system in IBD, looked at identifying a specific bacterial species, and were not representative of a feasible model of inflammation in IBD overall...

Human microbiota is a term conventionally used to define the normal flora of microbes living in all of us, most of which are resident in the gastrointestinal tract. Despite it having been known for some time that the vast majority of intestinal bacteria exert a strong influence on human life, recent technologic breakthroughs have made it possible to more accurately characterize the host microbial communities and explore their relationship with many human diseases. Notably, the evidence accumulated over the past 10 years suggests that a reasonable relationship can now be established between gut microbiota composition and the risk of cardiovascular disease...

PURPOSE OF THE REVIEW: Diabetes mellitus is a major cause of kidney disease [chronic kidney disease (CKD) and end-stage renal disease (ESRD)] and are both characterized by an increased risk of cardiovascular events. Diabetes and kidney disease are also commonly associated with a chronic inflammatory state, which is now considered a non-traditional risk factor for atherosclerosis. In the case of type 2 diabetes mellitus (T2DM), inflammation is mainly a consequence of visceral obesity, while in the case of CKD or ESRD patients on dialysis, inflammation is caused by multiple factors, classically grouped as dialysis-related and non-dialysis-related...

Five bacterial isolates from honey and bee gut were selected based on their high levansucrase activity and levan yield which were strongly positively correlated. All isolates showed good tolerance to temperature up to 70 °C, to NaCl up to 3 M and to 0.1% H2O2. They maintained over 59 and 64% survival at pH 9.0 and 2.0 respectively, but showed varying tolerance to 0.1% bile salts and pancreatic enzymes. Most isolates were susceptible to widely used antibiotics, but demonstrated diverse antimicrobial activity...

The objective was to determine the effects of prebiotics and synbiotics on adults with functional constipation (FC). Medline, Embase and the Cochrane Library were searched for literature published up to February 2015. We selected randomized controlled trials (RCTs) that reported administration of prebiotics or synbiotics to adults with FC. The end points included stool frequency, stool consistency and other symptoms related to constipation. Mean differences (MD) or standard mean differences (SMD) were used for continuous outcomes and risk ratios for discontinuous outcomes using a random-effects model...

Atopic dermatitis (AD) is a common chronic inflammatory skin disease affecting ~10-20% of the general population. AD is characterized by disturbances in epidermal barrier function and hyperactive immune response. Recently, changes in the skin and intestinal microbiome have been analyzed in more detail. The available data suggest a link between disturbed skin microbiome and course of the disease. Flares of the disease are associated with an expansion of Staphylococcus aureus on lesional skin and a substantial loss of biodiversity in skin microbiome...

In recent years, some new processes have been proposed to explain how alcohol may influence behavior, psychological symptoms and alcohol seeking in alcohol-dependent subjects. In addition to its important effect on brain and neurotransmitters equilibrium, alcohol abuse also affects peripheral organs including the gut. By yet incompletely understood mechanisms, chronic alcohol abuse increases intestinal permeability and alters the composition of the gut microbiota, allowing bacterial components from the gut lumen to reach the systemic circulation...

Irritable bowel syndrome (IBS) is heterogeneous. Patients need proper assessment and explanation of IBS pathophysiology and appropriate therapies. A low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) diet effectively reduces symptoms in 75% of patients. Best treatment for those nonresponsive will depend on the pathophysiological basis for symptom genesis, with the following possible abnormalities: (i) Visceral hypersensitivity and/or enhanced gut-brain communication: a low FODMAP diet is mainly targeted for this patient group...

BACKGROUND: Emerging evidence suggested that the prebiotic ability of β-glucan was intimately related to its molecular weight (Mw ). However, the effect of oat β-glucan with different Mw on gut homeostasis was inconsistent. Importantly, the understanding of the fermentation properties of oat β-glucan fractions was still limited. The aim of this study was to evaluate the prebiotic potential of raw and hydrolyzed oat β-glucan during in vitro fermentation by fecal microbiota and selected probiotic strains...

The human intestinal microbiome has important metabolic and immunological functions for the host and is part of the defense against pathogens in the gastrointestinal tract. Antibiotics, probiotics, dietary measures, such as prebiotics, and the relatively newly established method of fecal microbiota transplantation (FMT, also known as fecal microbiome transfer) all influence the intestinal microbiome. The FMT procedure comprises the transmission of fecal microorganisms from a healthy donor into the gastrointestinal tract of a patient...

Jayashree Ramasethu
Nosocomial or hospital acquired infections threaten the survival and neurodevelopmental outcomes of infants admitted to the neonatal intensive care unit, and increase cost of care. Premature infants are particularly vulnerable since they often undergo invasive procedures and are dependent on central catheters to deliver nutrition and on ventilators for respiratory support. Prevention of nosocomial infection is a critical patient safety imperative, and invariably requires a multidisciplinary approach. There are no short cuts...
