Campylobacter jejuni : biofilm formation and oxidative stress
(2009)Campylobacter jejuni (C. jejuni) is a zoonotic pathogen most often associated with poultry and the leading cause of bacterial gastroenteritis in the developed world. It is an obligate microaerobe, requiring low levels of ... -
Characterization of Campylobacter jejuni growing in biofilms under different conditions
(2005)The viability of C. jejuni biofilms growing in different conditions was investigated by conventional plate counts and microscopy after nucleic acid staining. Differences were detected for each condition tested. However, ... -
Characterization of genetic determinants for growth and structure of Listeria monocytogenes biofilms / by Nicholas Choy.
(2007, c200)This thesis investigated wild-type 'Listeria monocytogenes ' EGD and five of its corresponding mutant strains (M1, M4, M7, M11 and M14) for their ability to form biofilms on glass at 22°C and 37°C, with and without shear ... -
Characterization of sediment, sewage and 0157 E. coli: a comparison of their virulence genes, biofilm forming capacities, antibiotic resistance and level of reactive oxygen species (ROS)
(2018)Even though sediment Escherichia coli is a common source of contamination in freshwater environments, their virulence and physiological characteristics are not well studied. The goal of this study was to compare the virulence ... -
Effect of biofilm and the role of rpoS on the survival of a p-Nitrophenol-degrading Pseudomonas putida / by Miranda Maki.
(2008)Pseudomonas putida is a Gram negative bacterium that can be found naturally in the environment as planktonic free-living cells, or in concert with other bacterial species in biofilms. In this study, the P. putida strain ... -
Effect of periphytic Escherichia coli and lake water bacterial population on the biofilm establishment of a Shiga toxin producing Escherichia coli O157:H7 strain
(2015)Biofilm studies Escherichia coli (E. coli) have typically focused on 0157:H7 in defined, laboratory medium. While there is value in such studies, they offer little in the way of explaining the behaviour and interactions ... -
Effect of rpoS inactivation on biofilm formation of a p-nitrophenol degrading Pseudomonas putida strain
(2005)With the widespread existence of environmental pollutants in the modern world, effective, non-destructive means of remediation are becoming more and more desirable as an alternative to the traditional excavation and ... -
Expression of oxidative stress response genes in Campylobacter jejuni biofilms / by David Andrew Brookes.
(2007)'Campylobacter jejuni' is a Gram-negative microaerophilic bacterium that is widely believed to be the number one cause of food borne gastroenteritis and diarrhea caused by bacteria. The ability to form biofilms may provide ... -
Modulation of Listeria monocytogenes biofilms by Pseudomonas spp. secreted substances / by Lauren Davey.
(2008)Listeria monocytogenes, a food-borne pathogen associated with severe disease, forms resistant biofilms which enable it to persist in food processing environments. Recently, surface active compounds and other microbially ... -
Physiological adaptations contributing to stress survival in the foodborne pathogen Campylobacter jejuni
(2015-06-15)n spite of being considered fragile and fastidious, the zoonotic pathogen Campylobacter jejuni remains the leading cause of foodborne bacterial gastroenteritis in the developed world. Lacking many of the stress responses ... -
Pulp and paper mill bacteria as a potential source of novel encapsulation materials / by Peter R. Godin.
(2008)"A total of 194 bacteria were isolated from pulp and paper biofilms from a mill in Thunder Bay, Canada. Diversity of the 194 bacteria indicated that the amounts of bacteria found in these biofilms may be influenced by ...
