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...

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...

Effects of nisin and reutericyclin on resistance of endospores of Clostridium spp. to heat and high pressure
Download2013-05-01
Hofstetter, Simmon, Gebhardt, David, Ho, Linda, Gänzle, Michael G., McMullen, Lynn M.
The effects of high pressure, temperature, and antimicrobial compounds on endospores of Clostridium spp. were examined. Minimal inhibitory concentrations (MIC) of nisin and reutericyclin were determined for vegetative cells and endospores of Clostridium sporogenes ATCC 7955, Clostridium...

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...

Non digestible carbohydrates in the diet determine toxicity of irinotecan (CPT-11)/5-fluorouracil in rats independently of β-glucuronidase activity in intestinal lumen
DownloadFall 2012
Aim of this study was to assess effects of non-digestible carbohydrates on the pathobiology of mucosal injury after chemotherapy. Rats bearing colon tumor (n=6/diet) were fed diets including 8% (w/w) as either cellulose, inulin, fructo-oligosaccharide (OligoF), 50:50 (w/w) inulin and oligoF...

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...

Use of the fluorescent probe LAURDAN to label and measure inner membrane fluidity of endospores of Clostridium spp.
Download2012-10-01
Hofstetter, Simmon, Denter, Christian, Winter, Roland, McMullen, Lynn M., Gänzle, Michael G.
A method for measuring the fluidity of inner membranes of populations of endospores of Clostridium spp. with a fluorescent dye was developed. Cells of Clostridium beijerinckii ATCC 8260 and Clostridium sporogenes ATCC 7955 were allowed to sporulate in the presence of...
