Catechins are natural polyphenolic phytochemicals that exist in food and medicinal plants, such as tea, legume and rubiaceae. An increasing number of studies have associated the intake of catechins-rich foods with the prevention and treatment of chronic diseases in humans, such as inflammatory bowel disease (IBD). Some studies have demonstrated that catechins could significantly inhibit the excessive oxidative stress through direct or indirect antioxidant effects and promote the activation of the antioxidative substances such as glutathione peroxidases (GPO) and glutathione (GSH), reducing the oxidative damages to the colon...

Aim. Evaluation of the impact of gut microflora on the pathophysiology of MS. Results. The etiopathogenesis of MS is not fully known. Gut microbiota may be of a great importance in the pathogenesis of MS, since recent findings suggest that substitutions of certain microbial population in the gut can lead to proinflammatory state, which can lead to MS in humans. In contrast, other commensal bacteria and their antigenic products may protect against inflammation within the central nervous system. The type of intestinal flora is affected by antibiotics, stress, or diet...

Extended-spectrum β-lactamases (ESBLs) and plasmid mediated AmpC β-lactamases (pAmpC) are enzymes able to hydrolyze a large variety of β-lactam antibiotics, including 3(rd) generation cephalosporins and monobactams. Broilers and broiler meat products can be highly contaminated with ESBL and pAmpC-producing Escherichia coli, also known as extended-spectrum cephalosporins (ESC)-resistant E. coli, and can be a source for human infections. As few data are available on interventions to reduce ESC-resistant E...

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD...

Purpose The major causes of mortality after allogeneic hematopoietic-cell transplantation (allo-HCT) are relapse, graft-versus-host disease (GVHD), and infection. We have reported previously that alterations in the intestinal flora are associated with GVHD, bacteremia, and reduced overall survival after allo-HCT. Because intestinal bacteria are potent modulators of systemic immune responses, including antitumor effects, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HCT...

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...

Some scholars caution that long-term ad libitum feeding with probiotic fermented food poses potential health risks to baby animals. We conducted a feeding experiment to investigate the influence of ad libitum feeding of pre-and post-weaned piglets with a Bacillus subtilis fermented diet on the gut microbiome, gut metabolomic profiles, bile acid metabolism, proinflammatory cytokines and faecal consistency. Compared with piglets fed a Bacillus subtilis-supplemented pellet diet, piglets fed the Bacillus subtilis fermented liquid diet had lower intestinal bacterial diversity (P > 0...

(-)-Epigallocatechin 3-O-(3-O-methyl) gallate (EGCG3″Me) has exhibited multiple beneficial effects on the prevention of obesity in oolong tea. However, its absorption is relatively low, and the potential to be fully utilized is not completely elucidated. Therefore, with human flora-associated (HFA) mice model, the effect of EGCG3″Me on high fat diet-induced obesity was investigated by high-throughput sequencing. The shifts in relative abundance of the dominant taxa at the phylum, family and genus levels showed the dramatically effects of EGCG3″Me...

An abscess is defined as a collection of pus in various tissues of the body including skin and other organs. Abscesses most commonly are formed on the skin under the armpits, groin areas, and rectal areas. Most abscesses involve microbial infections with few remaining sterile. The treatment of abscesses includes both medical and surgical intervention. In the era of multidrug resistance, isolation and identification of the causative microbe and testing for antimicrobial susceptible patterns assume greater significance for the better management of patients, thereby reducing the resultant morbidity and mortality...

Harbour porpoises (Phocoena phocoena) are the most prevalent cetaceans in the North Sea. The fecal viral flora of 21 harbour porpoises stranded along the Dutch coastline was analyzed by a metagenomics approach. Sequences of a novel cetacean mastadenovirus, designated harbour porpoise adenovirus 1 (HpAdV-1), were detected. The sequence of a 23-kbp genomic region, spanning the conserved late region, was determined using primer walking. Phylogenetic analysis indicated that HpAdV-1 is most closely related to bottlenose dolphin adenovirus and clusters with Cetartiodactyla adenoviruses...

BACKGROUND: It has been postulated that colon cancer is the third cause of cancer death worldwide. Recently, colon-targeted drug delivery systems have been developed for improving systemic drug delivery and treatment of local colon associated diseases. Using such drug delivery systems increases the drug's effectiveness and results in reduced systemic side effects. Drug delivery systems formulated for the colon requires that the triggering of drug release mechanism is designed based on the colon's physiological conditions...

Tussah immunoreactive substance (TIS) comprises a number of active chemicals with various bioactivities. The current study investigated the effects of these substances on the sea cucumber Apostichopus japonicus. The specific growth rate (SGR) of TIS-fed sea cucumbers was significantly enhanced, whereas no significant difference in SGR was observed between those soaked in antibiotics and those fed with basal diet only. TIS also improved the immune response of the animals when given at a dose of 1.0% or 2.0%, as shown by increased phagocytic, lysozyme, superoxide dismutase, alkaline phosphatase, acid phosphatase, and catalase activities following injection with live Vibrio splendidus...

The importance of the intestinal microbiota of animals is widely acknowledged because of its vital role in the health of animals. There are complex communities of microbiota, which colonize the gastrointestinal tract. Intestinal microbiota are conductive to animal health and the development of the host immune system. Probiotics are commonly used dietary additives where they provide the host with many beneficial functions, such as modulating intestinal homeostasis and promoting gut health. These beneficial effects of probiotics may accrue from the inhibiting the growth of pathogenic bacteria and promoting the growth of beneficial flora in the gastrointestinal tract...

Paola Tognini
During childhood, our brain is exposed to a variety of environmental inputs that can sculpt synaptic connections and neuronal circuits, with subsequent influence on behavior and learning processes. Critical periods of neurodevelopment are windows of opportunity in which the neuronal circuits are extremely plastic and can be easily subjected to remodeling in response to experience. However, the brain is also more susceptible to aberrant stimuli that might lead to altered developmental trajectories. Intriguingly, postnatal brain development is paralleled by the maturation of the gut microbiota: the ecosystem of symbionts populating our gastro-intestinal tract...
