Inulin and fructo-oligosaccharides have divergent effects on colitis and commensal microbiota in HLA-B27 transgenic rats
Download2012-01-01
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...

Lactobacillus reuteri maintains a functional mucosal barrier during DSS treatment despite mucus layer dysfunction
Download2012
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...

Neutrophil elastase alters the murine gut mirobiota resulting in enhanced Salmonella colonization
Download2012
Hartmann, Martin, Sekirov, Inna, Finlay, B. Brett, Al-Zahrani, Fatimah, Willing, Benjamin P., Ferreira, Rosana B. R., Gill, Navkiran, Antunes, L. Caetano M.
The intestinal microbiota has been found to play a central role in the colonization of Salmonella enterica serovar Typhimurium in the gastrointestinal tract. In this study, we present a novel process through which Salmonella benefit from inflammatory induced changes in the microbiota in order to...

Resistance and Membrane Fluidity of Endospores of Clostridium spp. During Pressure-Assisted Thermal Processing in the Presence of Antimicrobials
DownloadSpring 2012
Endospores of Clostridium spp. pose an economic threat to the food industry and put consumers at risk of foodborne illness. An increase in consumer demand for minimally-processed, ready-to-eat products has driven research to examine ways to mitigate current thermal processing severity used to...

Small intestine early innate immunity response during intestinal colonization by Escherichia coli depends on its extra-intestinal virulence status
Download2016
Denamur, Erick, Tourret, Jérôme, Dion, Sara, Willing, Benjamin P., Wachtel, Sarah, Finlay, B. Brett, Dufour, Nicolas, Croxen, Matthew A.
Uropathogenic Escherichia coli (UPEC) strains live as commensals in the digestive tract of the host, but they can also initiate urinary tract infections. The aim of this work was to determine how a host detects the presence of a new UPEC strain in the digestive tract. Mice were orally challenged...

The intestinal microbiota plays a role in Salmonella-induced colitis independent of pathogen colonization
Download2011
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...

The role of intestinal microbiota in development of irinotecan toxicity and in toxicity reduction through dietary fibres in rats
Download2014
Baracos, Vickie, Dieleman, Levinus, Farhangfar, Arazm, Lin, Xiaoxi B., Gänzle, Michael G., Sawyer, Michael B., Valcheva, Rosica, Schieber, Andreas
CPT-11 is a drug used as chemotherapy for colorectal cancer. CPT-11 causes toxic side-effects in patients. CPT-11 toxicity has been attributed to the activity of intestinal microbiota, however, intestinal microbiota may also have protective effects in CP!-11 chemotherapy. This study aimed to...

Understanding the role of Clostridioides difficile and Vitamin D supplementation in shaping the gut microbiome of Canadian infants
DownloadSpring 2019
Introduction: The gut microbiome is shaped during infancy and has an important role in the development of both the immune and metabolic systems. Many early life exposures and events contribute to the composition of this complex intestinal environment, notably early infant diet and breastfeeding....
