A mechanistic model of intermittent gastric emptying and glucose-insulin dynamics following a meal containing milk components
Download2016
Cant, John P., Steele, Michael A., Stahel, Priska, MacPherson, Jayden A. R., Berends, Harma
To support decision-making around diet selection choices to manage glycemia following a meal, a novel mechanistic model of intermittent gastric emptying and plasma glucose-insulin dynamics was developed. Model development was guided by postprandial timecourses of plasma glucose, insulin and the...

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 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...

Chemically defined diet alters the protective properties of fructo-oligosaccharides and isomalto-oligosaccharides in HLA-B27 transgenic rats
Download2014
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...

Environmental particulate matter induces murine intestinal inflammatory responses and alters the gut microbiome
Download2013-01-01
Thiesen, Aducio, Rioux, Kevin P., Tso, Robert, Kish, Lisa, Barkema, Herman W., Madsen, Karen L., Vincent, Renaud, Wine, Eytan, Kaplan, Gilaad G., Hotte, Naomi, Gänzle, Michael G.
Background Particulate matter (PM) is a key pollutant in ambient air that has been associated with negative health conditions in urban environments. The aim of this study was to examine the effects of orally administered PM on the gut microbiome and immune function under normal and inflammatory...

Campylobacter jejuni colonization is associated with a dysbiosis in the cecal microbiota of mice in the absence of prominent inflammation
Download2013
Selinger, L. Brent, Inglis, G. Douglas, Uwiera, Richard R. E., Lone, Abdul, Xu, Yong
Background Campylobacter jejuni causes enterocolitis in humans, but does not incite disease in asymptomatic carrier animals. To survive in the intestine, C. jejuni must successfully compete with the microbiota and overcome the host immune defense. Campylobacter jejuni colonization success varies...

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...

Ketabi, Ali, Baracos, Vickie E., Field, Catherine J., Lin, Xiaoxi, Xue, Hongyu, Bibova, Ilona, Gänzle, Michael G., Dieleman, Levinus A., Sawyer, Michael B.
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...

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...

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...
