Cornell scientists link E. coli bacteria to Crohn's disease

08-07-2007 · EurekAlert!

A team of Cornell University scientists from the College of Veterinary Medicine, Weill Cornell Medical College and the College of Agriculture and Life Sciences have discovered that a novel group of E. coli bacteria -- containing genes similar to those described in uropathogenic and avian pathogenic E. coli and enteropathogenic bacteria such as salmonella, cholera and bubonic plague -- is associated with intestinal inflammation in patients with Crohn's disease in their research paper published July 12 by the ISME Journal: Multidisciplinary Journal of Microbial Ecology.

  1. Brown scientists map structure of DNA-doctoring protein complex
    12-06-2006 · EurekAlert!
    Mobile DNA, which inserts foreign genes into target cells, is a powerful force in the march of evolution and the spread of disease. Working with the lambda virus and E. coli bacteria, Brown University biologists have solved the structure of a six-protein complex critical to performing this gene-grafting surgery. The technique they developed could be used to reveal the structure of other critical protein complexes, landing the work on the cover of Molecular Cell.

  2. Rutgers scientists preserve and protect foods naturally
    08-20-2007 · EurekAlert!
    Chemists and food scientists at Rutgers joined forces to develop natural approaches to the prevention of food contamination and spoilage. They employed natural antimicrobial agents derived from sources such as cloves, oregano, thyme and paprika to create novel biodegradable polymers or plastics to potentially block the formation of bacterial biofilms on food surfaces and packaging. Biofilms may harbor multiple versions of infectious, disease-causing bacteria, such as Salmonella and E. coli.

  3. Bacteria control how infectious they become, study finds
    04-12-2007 · EurekAlert!
    The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off. Knowing how disease-causing bacteria, like Yersinia pestis and E. coli, do this may one day help scientists create drugs that control the expression of these genes, thereby making the bacteria harmless. The findings appear in the April 13 issue of the journal Molecular Cell.

  4. Stuck on you: CEACAM6 helps E. coli stick to intestinal lining in Crohn's disease
    05-24-2007 · EurekAlert!
    In Crohn's disease, the lining of the small intestine is abnormally colonized by E. coli organisms that are able to adhere to and invade intestinal epithelial cells. A new JCI study shows that these bacteria adhere to a region of intestinal epithelial cells known as the brush border in patients with Crohn's disease, but not in healthy individuals, and that this adhesion depends on expression of the receptor CEACAM6 on the epithelial cell surface.

    Scientists have provided new details about how proteins used to destroy bacteria and viruses may help treat Alzheimer's disease. Gunnar K. Gouras, associate professor of neurology and neuroscience at Weill Medical College of Cornell University, New York, and colleagues provide new insights into how these proteins, called antibodies, reduce the main hallmarks of Alzheimer's disease and raise hopes for a vaccine against the disease.

  7. Scientists find major susceptibility gene for Crohn's disease
    10-26-2006 · EurekAlert!
    Researchers report the discovery of a new genetic link to Crohn's disease. Mutations of a gene, which codes for a receptor in a major inflammatory pathway, are strongly associated with Crohn's, they found. Surprisingly, one type of mutation appears to confer significant protection, prioritizing a crucial target for drugs that might better manage Crohn's disease and ulcerative colitis. More than 1 million Americans have Crohn's or colitis, known collectively as inflammatory bowel disease.

    07-02-2007 · EurekAlert!
    People who have high cholesterol levels may be much more susceptible to a particular disease transmitted by the bites of ticks, a new study in mice suggests. Scientists infected mice with the bacterium that causes human granulocytic anaplasmosis, a disease with flu-like symptoms. Bacteria levels were 10 times greater in mice that were genetically predisposed to high cholesterol levels and that were also fed a high-cholesterol diet.

    Monitoring of pig carcasses and pig meat in slaughterhouses, butchers' premises and retail outlets will be undertaken in Ireland over the next two years in an attempt to determine how a human disease causing bacteria, Yersinia enterocolitica, enters the food chain, scientists announced today, Sept. 4, 2007, at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs Sept. 3-6 2007.

  10. Belly fat may drive inflammatory processes associated with disease
    03-13-2007 · EurekAlert!
    As scientists learn more about the key role of inflammation in diabetes and heart disease, new research from Washington University School of Medicine in St. Louis suggests that fat in the belly may be an important promoter of that inflammation. The researchers have confirmed that fat cells inside the abdomen secrete molecules that increase inflammation. This is the first evidence of a potential mechanistic link between abdominal fat and systemic inflammation.
