Project description:To investigate the regulatory targets of the RegR virulence regulon of rabbit specific enteropathogenic Escherichia coli strain E22
Project description:Despite the characterization of many aetiologic genetic changes. The specific causative factors in the development of sporadic colorectal cancer remain unclear. This study was performed to detect the possible role of Enteropathogenic Escherichia coli (EPEC) in developing colorectal carcinoma.
Project description:To investigate the regulatory targets of the RegR virulence regulon of rabbit specific enteropathogenic Escherichia coli strain E22 Single factor (genotype) with dye swaps.
Project description:Enterohemorrhagic Escherichia coli (EHEC) is a gram negative enteric bacterial pathogen that can cause hemorrhagic colitis and heamolytic uremic syndrome (HUS) in humans and is the cause of bloody diarrhoea and acute renal failure in children. We have studied the transcriptional response of a colon cell line (CaCo2) to infection by EHEC and another closely related enteric pathogen Enteropathogenic Escherichia coli (EPEC) and compared its response to a cervical cell line (Hela). We carried out microarray analysis on CaCo2 infected with EHEC O157H:7 EDL933 and EPEC E2348/69 at 4 hours of infection and analysis on Hela infected with EHEC also at 4 hours of infection
Project description:Within this study we demostrate that NleB2 from Enteropathogenic Escherichia coli is a arginine-glucose transferase. Using in vitro and in vivo assays we demostrate that control of the utelisation of UDP-GlcNAc or UDP-Glc is controlled by a single amino acid.
