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:Primary objectives: The study investigates whether a Escherichia coli Nissle-suspenison has a (preventive) antidiarrheal effect in patients with tumors who are treated with chemotherapeutic schemes which are associated with increased occurances of diarrhea. Diarrhea caused by treatment are thought to be reduced in intensity and/or frequency by the treatment with Escherichia coli Nissle-Suspension.
Primary endpoints: Common toxicity criteria (CTC) for diarrhea
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
Project description:The gut of chicken is mostly colonised with Campylobacter jejuni and with 100 fold less C. coli. The competitive ability of C. coli OR12 over C. jejuni OR1 has been examined in experimental broiler chickens following the observation that C. coli replaced an established C. jejuni intestinal colonisation within commercial chicken flocks reared outdoors (El-Shibiny, A., Connerton, P.L., Connerton, I.F., 2005. Enumeration and diversity of campylobacters and bacteriophages isolated during the rearing cycles of free-range and organic chickens. Applied Environmental Microbiology. 71, 1259-1266).
Project description:To investigate the regulatory targets of the RegR virulence regulon of rabbit specific enteropathogenic Escherichia coli strain E22
Project description:Leukemia inhibitory factor (LIF) is amongst the IL-6 family cytokines expressed in the lungs during pneumonia. However, the function of endogenous LIF during pneumonia has never been explored. The purpose of this study was to determine the transcriptional response to pneumonia in the lungs and whether or how this response is influenced by LIF. Mice received intratracheal instillations of vehicle (PBS) or Escherichia coli (10^6 CFU). Control IgG or anti-LIF specific IgG was included in the instillate. 24 hours after the challenge, lungs were collected for RNA isolation and microarray analysis. RNA from 3 separate groups of mice (3 mice per group) was analyzed: 1) 24h Vehicle/control IgG-treated; 2) 24h E. coli/control IgG-treated; and 3) 24h E. coli/anti-LIF-specific IgG.
Project description:In the bacterium Escherichia coli, RecG directs DNA synthesis during the repair of DNA double-strand breaks by homologous recombination. Examination of RecA binding during double-strand break repair in Escherichia coli in the presence and absence of RecG protein
