Clostridium difficile is the etiological agent of antibiotic-associated diarrhoea (AAD) and pseudomembranous colitis in humans. The role of the surface layer proteins (SLPs) in this disease has not yet been fully explored. The aim of this study was to investigate a role for SLPs in the recognition of C. difficile and the subsequent activation of the immune(More)
We have developed an apoptosis assay based on measurement of a neoepitope of cytokeratin-18 (CK18-Asp396) exposed after caspase-cleavage and detected by the monoclonal antibody M30. The total amount of caspase-cleaved CK18 which has accumulated in cells and tissue culture media during apoptosis is measured by ELISA. The sensitivity is sufficient for use in(More)
Clostridium difficile is the leading cause of hospital-acquired diarrhoea worldwide, and if the bacterium is not cleared effectively it can pose a risk of recurrent infections and complications such as colitis, sepsis and death. In this study we demonstrate that surface layer proteins from the one of the most frequently acquired strains of C. difficile,(More)
PUFAs (polyunsaturated fatty acids) can modify immune responses, so they may have potential therapeutic effects in inflammatory disorders. We previously demonstrated that the cis-9, trans-11 isomer of the PUFA conjugated linoleic acid (CLA) can modulate dendritic cell (DC) cytokine production. Since DCs play a central role in initiating inflammation by(More)
Cancer, much like most human disease, is routinely studied by utilizing model organisms. Of these model organisms, mice are often dominant. However, our assumptions of functional equivalence fail to consider the opportunity for divergence conferred by ~180 Million Years (MY) of independent evolution between these species. For a given set of human disease(More)
Clostridium difficile is an anaerobic, Gram-positive, and spore-forming bacterium that is the leading worldwide infective cause of hospital-acquired and antibiotic-associated diarrhea. Several studies have reported associations between humoral immunity and the clinical course of C. difficile infection (CDI). Host humoral immune responses are determined(More)
Clostridium difficile is a nosocomial pathogen prevalent in hospitals worldwide and increasingly common in the community. Sequence differences have been shown to be present in the Surface Layer Proteins (SLPs) from different C. difficile ribotypes (RT) however whether these differences influence severity of infection is still not clear. We used a molecular(More)
