BACKGROUND: IBD is considered as one of the major public health concerns worldwide. The pathophysiology and gut microbial alteration during inflammatory bowel disease (IBD) are still not completely understood. Gut microbiota is implicated in most of the gastro-intestinal (GI) diseases including IBD. From the time of gut microbiota establishment and through aging, it undergoes a lot of changes in the composition. METHODS: In a healthy state, the composition of beneficial microbes in the gut is comparatively higher and due to factors such as malnutrition, use of antibiotics and any underlying diseases allow the colonization and invasion of pathogens...

Emerging data from epidemiologic, microbiome, and physiology research in patients with functional bowel disorders (FBDs) provide evidence for a linkage between alterations in the intestinal microbiota and FBDs. However, currently most of the data is based on association studies, and the causality role of the microbiota in these disorders is not established. Growing evidence for compositional changes and the increasing recognition of the association between the intestinal microbiota and gut-brain functions that are relevant to the pathophysiology and/or clinical symptoms of FBDs have led to increased interest in manipulating the intestinal microbiota for the treatment of these disorders...

Gut microbes are capable of producing most neurotransmitters found in the human brain. Evidence is accumulating to support the view that gut microbes influence central neurochemistry and behavior. Irritable bowel syndrome is regarded as the prototypic disorder of the brain-gut-microbiota axis that can be responsive to probiotic therapy. Translational studies indicate that certain bacteria may have an impact on stress responses and cognitive functioning. Manipulating the gut microbiota with psychobiotics, prebiotics, or even antibiotics offers a novel approach to altering brain function and treating gut-brain axis disorders, such as depression and autism...

Genes, bacteria, and immunity contribute to the pathogenesis of inflammatory bowel disease. Most genetic risk relates to defective sensing of microbes and their metabolites or defective regulation of the host response to the microbiota. Because the composition of the microbiota shapes the developing immune system and is determined in early life, the prospect of therapeutic manipulation of the microbiota in adulthood after the onset of disease is questionable. However, the microbiota may be a marker of risk and a modifier of disease activity and a contributor to extraintestinal manifestations and associations in some patients with inflammatory bowel disease...

BACKGROUND: Although single nucleotide polymorphisms in the NOD2 (nucleotide-binding oligomerization domain-containing 2) gene have been associated with the pathogenesis of Crohn's disease (CD), little is known about the role of nonpolymorphic wild-type (WT) NOD2 genes in the gut. To date, most animal studies addressing the role of WT NOD2 have been conducted using healthy (ileitis/colitis-free) mouse strains, and have attributed a modulating effect to the gut microbiome, partly based on 16S rRNA sequencing...

BACKGROUND: In the United States over 1.4 million people suffer from inflammatory bowel disease (IBD). Therefore, there is a pressing need for the development of novel molecular therapeutics targeting pro-inflammatory mediators. Recently a novel interleukin-1 family member, IL-36γ was shown to be up-regulated in patients with inflammatory bowel disease (IBD) and to play an important role in healing of acute intestinal damage in mice, however, the function of IL-36γ with regards to T helper (TH) cell differentiation during gut inflammation remains undefined...

Certain members of the microbiota genus Bifidobacterium are known to positively influence host well-being. Importantly, reduced bifidobacterial levels are associated with inflammatory bowel disease (IBD) patients, who also have impaired epithelial barrier function, including elevated rates of apoptotic extrusion of small intestinal epithelial cells (IECs) from villi-a process termed 'cell shedding'. Using a mouse model of pathological cell shedding, we show that mice receiving Bifidobacterium breve UCC2003 exhibit significantly reduced rates of small IEC shedding...

Inflammatory bowel disease (IBD) is a multifactorial disease. A breach in the mucosal barrier, otherwise known as "leaky gut," is alleged to promote mucosal inflammation by intensifying immune activation. However, interaction between the luminal antigen and mucosal immune system is necessary to maintain mucosal homeostasis. Furthermore, manipulations leading to deregulated gut permeability have resulted in susceptibility in mice to colitis as well as to creating adaptive immunity. These findings implicate a complex but dynamic association between mucosal permeability and immune homeostasis; however, they also emphasize that compromised gut permeability alone may not be sufficient to induce colitis...

Current treatment for pediatric IBD patients is often ineffective, with serious side effects. Manipulating the gut microbiota via fecal microbiota transplantation (FMT) is an emerging treatment approach but remains controversial. We aimed to assess the composition of the fecal microbiome through a comparison of pediatric IBD patients to their healthy siblings, evaluating risks and prospects for FMT in this setting. A Case-Control (Sibling) Study was conducted analyzing fecal samples of six children with Crohn's Disease (CD), six children with Ulcerative Colitis (UC) and 12 healthy siblings by metagenomic sequencing...

Toxoplasma gondii is an intensely studied protozoan parasite. It is also used as a model organism to research additional clinically relevant human and veterinary parasites due to ease of in vitro culture and genetic manipulation. Recently, it has been developed as a model of inflammatory bowel disease, due to their similar pathologies. However, researchers vary widely in how they use T. gondii, which makes study comparisons and interpretation difficult. The aim of this review is to provide researchers with a tool to: (i) determine the appropriateness of the different T...

Visceral pain is a significant and prevalent feature of several disorders including the functional gastrointestinal disorder, irritable bowel syndrome (IBS). Treatment strategies are limited and often unsatisfactory which has opened up new research avenues into the aetiology of visceral pain. This research has led to an increased appreciation of the role of the brain gut axis in modulating viscera pain responses. More recently, the interactions between the gut microbiota and the central nervous system have emerged indicating that visceral pain related disorders may be prospective candidates for symptom relief via microbial manipulation...

The molecules and pathways of the gut-brain axis represent new targets for developing methods to diagnose and treat psychiatric disorders. Manipulation of the gut microbiome with probiotics may be a therapeutic strategy with the potential to relieve gastrointestinal (GI) comorbidities and improve psychiatric symptoms. Candida albicans and Saccharomyces cerevisiae, commensal yeast species, can be imbalanced in the unhealthy human microbiome, and these fungal exposures were previously found elevated in schizophrenia...

BACKGROUND/PURPOSE: Transamniotic stem cell therapy (TRASCET) with amniotic fluid mesenchymal stem cells (afMSCs) has been shown to mitigate bowel damage in a rodent model of gastroschisis. As a prerequisite to clinical translation, we sought to study TRASCET in a larger animal model. METHODS: New Zealand rabbit fetuses (n=64) with surgically created gastroschisis were divided into three groups. One group (untreated) had no further manipulations. Two groups received volume-matched intraamniotic injections of either saline or a suspension of afMSCs...

It is our clinical impression that age and incision length are more strongly associated with surgical site infection (SSI) following colic surgery than skin closure or wound protection method. Therefore, the objective of this observational clinical cohort study was to identify the risks for SSI in horses undergoing colic surgery. Data collection included pre-, intra-, and postoperative variables. Variables with P < 0.2 following univariable analysis were used in a logistic regression multivariable model...
