The binding of recombinant fragments of the C-terminal cell-binding domains of the two large exotoxins, toxin A (TcdA) and toxin B (TcdB), expressed by Clostridium difficile and a library consisting of the most abundant neutral and acidic human milk oligosaccharides (HMOs) was examined...

Chemically defined diet alters the protective properties of fructo-oligosaccharides and isomalto-oligosaccharides in HLA-B27 transgenic rats

Koleva, Petya, Ketabi, Ali, Dieleman, Levinus A., Gänzle, Michael G., Valcheva, Rosica
Non-digestible oligosaccharides (NDO) were shown to reduce inflammation in experimental colitis, but it remains unclear whether microbiota changes mediate their colitis-modulating effects. This study assessed intestinal microbiota and intestinal inflammation after feeding chemically defined...

Inulin and fructo-oligosaccharides have divergent effects on colitis and commensal microbiota in HLA-B27 transgenic rats

Koleva, Petya, Dieleman, Levinus, Sun, Xu, Gänzle, Michael G., Valcheva, Rosica
Modulation of intestinal microbiota by non-digestible carbohydrates may reduce inflammation in inflammatory bowel disease (IBD). The aim of the present study was to assess the effects of inulin and fructo-oligosaccharides (FOS) on intestinal microbiota and colitis in HLA-B27 transgenic rats, a...

Intestinal microbiota mediate toxicity of irinotecan (CPT-11) cancer therapies and cause systemic infection after CPT-11-induced loss of barrier function. The intestinal microbiota and their functions are thus potential targets for treatment to mitigate CPT-11 toxicity. However, microbiota...

Isomaltodextrin dose-dependently reduces colitis development in HLA-B27 rat colitis model with associated changes to gut microbiota composition and short chain fatty acid production
DownloadFall 2021
Prevalence rates for inflammatory bowel diseases (IBD) worldwide have been drastically increasing over recent decades. IBD is characterized by altered intestinal microbiome (i.e. dysbiosis), described by reduced strict butyrate-producing anaerobes versus increased facultative anaerobes in...

Lactobacillus reuteri maintains a functional mucosal barrier during DSS treatment despite mucus layer dysfunction

Rang, Sara, Roos, Stefan, Phillipson, Mia, Holm, Lena, Dicksved, Johan, Willing, Ben P., Petersson, Joel, Schreiber, Olof
Treatment with the probiotic bacterium Lactobacillus reuteri has been shown to prevent dextran sodium sulfate (DSS)-induced colitis in rats. This is partly due to reduced P-selectin-dependent leukocyte- and platelet-endothelial cell interactions, however, the mechanism behind this protective...

The intestinal microbiota plays a role in Salmonella-induced colitis independent of pathogen colonization

Antunes, L. Caetano M., Gill, Navkiran, Russell, Shannon L., Finlay, B. Brett, Ferreira, Rosana B., Croxen, Matthew A., Willing, Benjamin P.
The intestinal microbiota is composed of hundreds of species of bacteria, fungi and protozoa and is critical for numerous biological processes, such as nutrient acquisition, vitamin production, and colonization resistance against bacterial pathogens. We studied the role of the intestinal...

There is an increase in the prevalence of inflammatory bowel disease (IBD) worldwide, and this appears to be associated with an increase in the consumption of a Western diet high in fat and sugar, and low in fiber. Previous work shows that two-day exposure to high sugar diets increases the...
