The gut microbiota has emerged as a key factor in the pathogenesis of intestinal viruses, including enteroviruses, noroviruses and rotaviruses (RVs), where stimulatory inhibitory effects on infectivity have been reported. With aim determining whether members interact with RVs during infection, combination anti-RV antibody labeling, fluorescence-activated cell sorting 16S rRNA amplicon sequencing was used to characterize interaction between specific bacteria RV stool samples children...

Abstract Microplastics (MPs) are a widely recognized global problem due to their prevalence in natural environments and the food chain. However, impact of microplastics on human microbiota possible biotransformation gastrointestinal tract have not been well reported. To evaluate potential risks at digestive level, completely passing single dose polyethylene terephthalate (PET) through was simulated by combining harmonized static model dynamic simgi model, which recreates different regions...

The microbial populations of the human intestinal tract and their relationship to specific diseases have been extensively studied during last decade. However, characterization bile microbiota as a whole has hampered by difficulties in accessing biological samples lack adequate methodologies assess molecular studies. Although few reports described biliary some hepatobiliary diseases, healthy individuals not described. With this mind, goal present study was generate fundamental knowledge on...

The accumulation of microplastics (MPs) in the environment as well their presence foods and humans highlight urgent need for studies on effects these particles humans. Polylactic acid (PLA) is most widely used bioplastic food industry medical field. Despite its biodegradability, biocompatibility, "Generally Recognized As Safe" (GRAS) status, recent animal model have shown that PLA MPs can alter intestinal microbiota; however, to date, no been reported possible gut health consequences intake...

This paper investigates the mutual interactions between lipids and red wine polyphenols at different stages of gastrointestinal tract by using simgi® dynamic simulator. Three food models were tested: a Wine model, Lipid model (olive oil + cholesterol) (red olive cholesterol). With regard to polyphenols, results showed that co-digestion with slightly affected phenolic profile after digestion. In relation lipid bioaccessibility, tended increase percentage bioaccessible monoglycerides, although...

Little is known about the bacteria that reside in human gallbladder and mechanisms allow them to survive within this harsh environment. Here we describe interactions between two strains from a bile sample, one Ruminococcus gauvreauii (IPLA60001), belonging Lachnospiraceae family, other, designated as Ruminococcoides bili (IPLA60002T; DSM 110008) most closely related bromii family Ruminococcaceae. We provide evidence for salt resistance sporulation these new strains. Both differed markedly...

Grape pomace (GP) is a winemaking by-product rich in polyphenols and fibre. Supplementation with GP extracts has shown potential benefits against oxidative stress- inflammation-related pathologies. As new nutritional target, this paper explores the impact of ingestion grape extract on intestinal barrier functionality. A was sequentially subjected to gastrointestinal colonic digestion using dynamic simulator (simgi®). This generated two simulated fluids: intestinal-digested (IDE)...

Recent dietary habits and lifestyle could explain the shaping of gut microbiota composition and, in consequence, increasing prevalence certain pathologies. However, little attention has been paid to influence diet on microbiotas, other than microbiota. This is important cholelithiasis, given that changes production bile acids may affect gallbladder microbial communities. Our aim was assess association between regular intake composition. Fourteen adults with cholelithiasis 14 controls,...

A strictly anaerobic, resistant starch-degrading, bile-tolerant, autolytic strain, IPLA60002T, belonging to the family Ruminococcaceae, was isolated from a human bile sample of liver donor without hepatobiliary disease. Cells were Gram-stain-positive cocci, and 16S rRNA gene whole genome analyses showed that Ruminococcus bromii phylogenetically closest related species novel strain though with average nucleotide identity values below 90 %. Biochemically, new isolate has metabolic features...

Bacteria-host interactions are mediated by different microbial associated molecular patterns which most often surface structures such as, among others, exopolysaccharides (EPSs). In this work, the capability of two isogenic EPS-producing Bifidobacterium animalis subsp. lactis strains to modulate gut microbiota healthy mice, was assessed. Each strain produces a type polymer; ropy S89L synthesized rhamnose-rich, high-molecular weight EPS in highest abundance than non-ropy DMS10140 one. BALB/c...

Background SARS-CoV-2 and COVID-19 are still active in the population. Some patients remained PCR-positive for more than 4 weeks, called “persistently PCR-positive”. Recent evidence suggests a link between gut microbiota susceptibility to COVID-19, although no studies have explored persistent PCR conditions. We aimed evaluate relationship positive RT-PCR, microbiome, individual host determinants. Methods A shotgun metagenomic analysis was conducted on fecal samples from 28 individuals...
