Diet and environment shape fecal bacterial microbiota composition and enteric pathogen load of grizzly bearsDownload
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...
Resistance and Membrane Fluidity of Endospores of Clostridium spp. During Pressure-Assisted Thermal Processing in the Presence of AntimicrobialsDownload
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...
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...
The role of intestinal microbiota in development of irinotecan toxicity and in toxicity reduction through dietary fibres in ratsDownload
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 ratsDownload
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...
“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...
