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...

Intravaginal lactic acid bacteria modulated local and systemic immune responses and lowered the incidence of uterine infections in periparturient dairy cows
Download2015
Dunn, Suzanna M., Odhiambo, John F., Farooq, Umar, Ametaj, Burim N., Lam, Tran, Deng, Qilan
The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB) cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant...

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...

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
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...

Repeated oronasal exposure to lipopolysaccharide induced mucosal IgA responses in periparturient dairy cows
Download2014
Dunn, Suzanna M., Iqbal, Summera, Zebeli, Qendrim, Mansmann, Dominik A., Ametaj, Burim N.
This study investigated the effects of repeated oronasal treatment with lipopolysaccharide (LPS) on the humoral immune responses in saliva, vaginal mucus, and the plasma markers of the acute phase response in periparturient dairy cows. One hundred pregnant Holstein cows were administered either 3...

Rheological behavior and nano-microstructure of complex fluids: Biomedical and Bitumen-Heavy oil applications
DownloadFall 2010
The main objective of this research was to exploit the interrelations between the rheological behavior and nano-microstructure of complex fluids in solving two state-of-the-art problems, one in the field of biomedical engineering: controlling the amount and characteristics of bioaerosol droplets...

Short-chain fatty acids influence host immunity, mucus secretion and microbial community structure to reduce enteritis
DownloadFall 2016
Optimal intestinal health is critical to overall host well-being, and acute and chronic enteric inflammatory diseases impart a significant detrimental impact on Canadians. The consumption of dietary fibre (DF) has long been associated with providing a health benefit to individuals, and regulatory...

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...

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...
