Bariatric surgery drives major rearrangements of the intestinal microbiota including the biofilm composition.

Bariatric surgery drives major rearrangements of the intestinal microbiota including the biofilm composition. Front Biosci (Elite Ed). 2018 Jun 01;10:495-505 Authors: Campisciano G, Cason C, Palmisano S, Giuricin M, Rizzardi A, Croce LS, De Manzini N, Comar M Abstract The intestinal microbiota disequilibrium has been associated with obesity, while the role of the gut mucosal biofilms in this pathology is still unknown. We analysed the changes in the intestinal microbiota of obese patients after bariatric surgery with the aim of disclosing the rearrangement of the biofilm configuration. Although the bariatric surgery drives major rearrangements of the gut microbiota, obese patients maintain the Prevotella enterotype before and after surgery, as shown by normal weight patients, with an increase of Bacteroides vulgatus and Bacteroides uniformis. The Bacteroides enterotype guarantees the strong ability to form a biofilm which allows a more efficient digestion of polysaccharides than planktonic communities and leads to the production of acetate which is a key player to inhibit enteropathogens. Additionally, the laparoscopic gastric bypass induces an increase of Hafniaalvei (Proteobacteria), a facultative anaerobic bacterium involved in intestinal and inflammatory disorders. Bariatric surgery influences the microbial composition of gut biofilm. Further studies are needed to elucidate the impact of this variation on recovery after surgery and on weight loss. ...

Abstract The global obesity epidemic has necessitated the search for better intervention strategies including the exploitation of the health benefits of some gut microbiota and their metabolic products. Therefore, we examined the gut microbial composition and mechanisms of interaction with the host in relation to homeostatic energy metabolism and pathophysiology of dysbiosis-induced metabolic inflammation and obesity. We also discussed the eubiotic, health promoting effects of probiotics, and prebiotics as well as epigenetic modifications associated with gut microbial dysbiosis and risk of obesity. High-fat/carboh...

This study was to investigate the effects of ethanol extract of propolis (EEP) on the gut microbiota, and to analyze the associations between these alterations of gut microbiota and insulin resistance and obesity in high fat diet (HFD)-fed mice.Male C57BL/6J mice were fed with chow diet, high-fat diet, and high-fat diet supplemented with 1% EEP or 2%EEP. EEP supplementation reduced HFD-induced weight gain and liver fat accumulation, proinflammatory cytokines and insulin resistance, and improved glucose tolerance and lipid profile. Meanwhile, EEP supplementation in HFD-fed mice increased anti-obesity and anti-inflammatory b...

Abstract Modification of chestnut starch with amylosucrase from Deinococcus geothermalis (DGAS) increases the proportion of resistant starch. DGAS-modified chestnut starch (DMCS) attenuates obesity in diet-induced obese mice via a receptor of short chain fatty acids (SCFAs), G-protein-coupled receptor 43. SCFAs are gut microbial metabolites produced by fermenting resistant starch and have key roles in the obesity-ameliorating effects of DMCS. Here, we evaluated the mechanical links among DMCS-induced changes in the gut microbiota, consequent production of microbial metabolites, and host genetic responses. Suppleme...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

Conclusions: These findings suggest that HON can prevent diet-induced obesity and its associated diseases by regulating the gut microbiota and improving microbial metabolite levels. Moreover, our findings indicate that sex may be an important factor affecting HON activity.

This study aimed to investigate the long-term effects of an Akkermansia muciniphila subtype (A. muciniphilasub) on high-fat diet-induced obesity and diabetes, and to evaluate whether this subtype can alleviate their complicated mental disorders. Whole genome sequencing and short chain fatty acid production analysis in supernatant of pure culture were performed. Female adult C57BL/6 mice were fed a high-fat diet or a normal chow diet and were gavaged with A. muciniphilasub or phosphate-buffered saline daily for 10 months. Body weight, food consumption and blood glucose were measured. At the end of the treatment period, all ...

A traditional Chinese medicine dietary therapy (TCMDT) diet, consisted of whole grains and traditional Chinese medicines, is traditionally used to lessen hyperglycemia and reduce obesity. The Simulator of the human intestinal microbial ecosystem (SHIME) was used for studying the effect of the TCMDT diet on gut microbiota and short chain fatty acids. The TCMDT d...
