Characterization of novel envelope proteins and their relationship with the Cpx response and stress resistance in Escherichia coli
DownloadFall 2022
Stress is a major factor every organism needs to mitigate to survive. Environmental factors such as oxygen content, temperature, and alkalinity can all induce stress and prevent life from progressing. For Escherichia coli and other members of the mammalian gastrointestinal tract they need to...

Background: The Human Microbiome is an area of increasing interest, both in and outside of the scientific community. While overall knowledge has increased exponentially, many aspects remain unclear, such as mechanisms of host-interaction and persistence. Intracellular bacteria have previously...

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...

Provided that infectious prions (PrPTSE) are inactivated, composting of specified risk material (SRM) may be a viable alternative to rendering and land filling. The overall objective of this research was to utilize laboratory-scale composters to assess the degradation of SRM and PrPTSE during...

Crystallization and preliminary diffraction studies of TraF, a component of the Escherichia coli type IV secretory system
Download2004
Manchak, J., Hayakawa, K., Audette, G.F., Holland, S.J., Frost, L.S., Hazes, B.
TraF, a component of the Escherichia coli type IV secretory system, has been crystallized and preliminary X-ray diffraction data have been collected. TraF is a 26 kDa protein encoded by the E. coli F plasmid and is required for conjugative plasmid transfer and the formation of sex pili. The...

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...

Effect of Antimicrobial Exposure on Clostridioides difficile (C. difficile) Colonization of the Infant Gut Microbiota in the Canadian Healthy Infant Longitudinal Development (CHILD) Birth Cohort
DownloadSpring 2020
Introduction: Antimicrobial exposure in early life has been associated with gut microbiota dysbiosis and development of allergic diseases in childhood. In adults and older children, C. difficile is the major pathogen responsible for antibiotic-induced diarrhea but the effect of colonization with...

Introduction By 2030, 1/100 Canadians are predicted to be diagnosed with inflammatory bowel diseases (IBD); approximately 25% of cases are diagnosed in children. IBD include Crohn disease (CD) and ulcerative colitis (UC), and manifest with chronic gastrointestinal inflammation. Pathogenesis...

Mixing displays a major role in the growth of photosynthesis microorganisms in active suspensions: it gives access to nutrients, improves the microorganisms’ exposure to light, and homogenizes temperature distribution in photobioreactors (PBRs). Therefore, mixing is an essential factor in the...
