Relationships among diet, the gastrointestinal microbiota, and mood
… systems, and maintaining or modulating the gastrointestinal microbiota. Cross-sectional and preclinical studies have demonstrated improvements to mental health following dietary interventions, but there is a dearth of evidence from clinical intervention trials to support dietary …

Gastrointestinal microbiota community composition has significant effects on systemic immune responses
… systemic immune responses. Colonization of the gastrointestinal (GI) tract is initiated during birth and continually seeded from the individual’s environment. Gastrointestinal microorganisms for a mutualistic relationship with the host, playing a central role in developing and modulating host …

Relationships between circadian rhythms, timing of eating behaviors, and the human gastrointestinal microbiota
… gained recent attention is the modulation of the gastrointestinal microbiota. Microbiota interventions have come into the spotlight because of the proposed relationships between the microbial community’s composition, function, and human health. One of the most common strategies for modulating the …

Molecular characterisation of selected gastrointestinal microbiota in South African HIV-positive patients during HAART
… diarrhoea due to the disruption of the gastrointestinal microbiota caused by either the HIV-infection or the use of antibiotics and drugs such as highly active antiretroviral therapy (HAART). An imbalance in the microbial composition, attributable to a disturbed mucosal barrier, as well …

Using Culturomics to Characterize the Gastrointestinal Microbiota of Donors for Patients with Bipolar Disorder Experiencing Depression
… treatments. Bacteria residing in the human gastrointestinal tract communicate with the central nervous system through a bi-directional network, referred to as the gut-brain axis, which can influence mood and behaviour. Fecal microbiota transplantation (FMT) has been shown to alter the gut …

An investigation of the effects of diet on the gastrointestinal microbiota, inflammation, and metabolic endotoxemia in adults
… interactions including the modulation of the gastrointestinal (GI) microbiota and bacterial fermentation end-products, GI barrier structure and function, and the enterohepatic circulation of bile acids. One of the mechanisms by which consumption of dietary fibers may contribute to decreased …

Understanding the role of human microbiota on sensory perception
… can also be affected by interactions between the gastrointestinal microbiota and the chemosensory systems. Despite growing interest, the sensory-oriented microbiome field suffers from obvious limitations due to its recent emergence. As a result, little efforts has been devoted to elucidating: a) …

Molecular characterization of ABC-type multidrug efflux systems in Bifidobacterium longum subsp. longumT JCM 1217
A healthy and stable gastrointestinal microbiota is a vital feature of the innate immune system. It affords the host numerous health benefits and acts as a barrier against opportunistic gut infections. Probiotic bacterial supplements are, therefore, widely used in industry to promote good health. …

Indices of gut health and intestinal microbial ecology of the cat as affected by ingestion of select carbohydrates varying in fermentative capacity
… impact of select fermentable carbohydrates on gastrointestinal health outcomes and microbial ecology of domestic cats. Four studies were designed to address two major research objectives: 1) to determine nutrient digestibility and fecal fermentative end-product outcome variables as affected by …

The Fecal Microbiota of Healthy and Diarrheic Calves Before, During and at Recovery From Diarrhea
The changes associated with the gastrointestinal microbiota before, during and after neonatal calf diarrhea still needs to be fully understood and described. The first chapter of this thesis reviews our current understanding of the composition of a “healthy” fecal microbiome, microbial changes …

On-trap derivatization of short-chain fatty acids
<p>It has recently been hypothesized that gastrointestinal microbiota modulate immune response by the production of short-chain fatty acids (SCFAs). There is a need for rapid, selective analytical methodology capable of trace analysis of SCFAs in complex biological matrices. Previous studies by …

Shiga Toxin-Producing Escherichia coli: a Public Health Challenge in the Pre-Harvest Stage of the Farm-to-Table Continuum
Escherichia coli is part of the normal gastrointestinal microbiota of many animals, especially cattle. While most strains are commensal, Shiga toxin-producing E. coli (STEC) can cause severe human illness. Pathogenicity of STEC is associated with genes such as those encoding Shiga toxins, …

Effect of cereal type and commensal bacteria on availability of methionine sources and intestinal physiology in pigs
… conducted to determine the contribution of the gastrointestinal microbiota to variation in bioefficacy of methionine sources and the interrelationship between intestinal microbiota and cereal grain type with respect to gastrointestinal physiology. Apparent gastrointestinal absorption of …

Towards engineering the gut microbiota
The human gastrointestinal tract is home to a dense and dynamic microbial community. Recent advancements in sequencing technology have revealed numerous relationships between the composition of these communities and human and health and disease. In some cases, researchers have shown causal …

The relevance of bacterial isoprenoid biosynthetic pathways for host-microbe interactions
… in microbial diversity in the murine gut microbiota (by next generation sequencing) following oral administration of a common anti-cholesterol drug Rosuvastatin (RSV) that targets mammalian and bacterial HMG-CoA reductase (HMG-R) for inhibition of MVAL formation. In tandem we identified …

Colonization dynamics of oro-gastrointestinal microbes critical to infant health
The gastrointestinal microbiota is intimately tied to a person’s health and well-being. This collection of bacteria, archaea, and fungi is assembled during a person’s infancy and achieves the stability of an “adult-like” microbiota in early childhood. Research has begun to uncover several host and …

Preventive Measures in Aquaculture: Isolation, Application and Effects of Probiotics on Atlantic cod (Gadus morhua L.) Rearing at Early Stages
… probionts were selected from the natural microbiota of cod larviculture at an experimental station in Iceland, based on several in vitro tests. Our study demonstrated that 14% of screened bacteria (n=188) had antagonistic properties towards fish pathogens. The majority of the isolates were …
