Willing, Benjamin P., Finlay, B. Brett , Thanachayanont, Teerawat, Croxen, Matthew, Vacharaksa, Anjalee
Host resistance to bacterial infections is thought to be dictated by host genetic factors. Infections by the natural murine enteric pathogen Citrobacter rodentium (used as a model of human enteropathogenic and enterohaemorrhagic E. coli infections) vary between mice strains, from mild...

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...

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...

Development of ruminal and fecal microbiomes are affected by weaning but not weaning strategy in dairy calves
Download2016
Khafipour, Ehsan, Steele, Michael A., Meale, Sarah J., Plaizier, Jan C., Li, Shucong, Derakhshani, Hooman, Azevedo, Paula
The nature of weaning, considered the most stressful and significant transition experienced by dairy calves, influences the ability of a calf to adapt to the dramatic dietary shift, and thus, can influence the severity of production losses through the weaning transition. However, the effects of...

Diet and environment shape fecal bacterial microbiota composition and enteric pathogen load of grizzly bears
Download2011-01-01
Northrup, Joseph M., Cristescu, Bogdan, Schwab, Clarissa, Stenhouse, Gordon B., Gänzle, Michael G.
Background Diet and environment impact the composition of mammalian intestinal microbiota; dietary or health disturbances trigger alterations in intestinal microbiota composition and render the host susceptible to enteric pathogens. To date no long term monitoring data exist on the fecal...

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...

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...

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...

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...
