A special protein in the lining of the stomach has been shown to be an important part of the body's defense against the stomach ulcer bacterium Helicobacter pylori in a new study from the Sahlgrenska Academy. The discovery may explain why the bacterium makes some people more ill than others. The study was conducted in collaboration with researchers at universities in Brisbane and Melbourne and has been published in the scientific journal Public Library of Science Pathogens. "Half of all...

Spanish scientists say they've identified substances that can block a chemical pathway needed by bacteria that cause stomach ulcers and other diseases. Professor Javier Sancho and colleagues at Zaragoza University said they knew from past research that blocking flavodoxin, a key protein needed by Helicobacter pylori bacteria for survival, could be the key to developing antibiotics specifically targeting the gastritis- and ulcer-causing bacteria. Sancho's team screened 10,000 chemicals for...

Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world's population, causing stomach ulcers and other diseases. They identified a group of substances that block a key chemical pathway that the bacteria need for survival. Their study, which could lead to new, more effective antibiotics to fight these hard-to-treat microbes, is scheduled for the October 16 issue of ACS Chemical Biology, a monthly...

Although it has been demonstrated that Helicobacter pylori causes gastric cancer, it is still controversial that whether H. pylori eradication therapy is effective in primary prevention of gastric cancer. This is especially important for Yamagata Prefecture, a region of Japan with the second highest incidence of gastric cancer in the world. A research article to be published on September 14, 2009 in the World Journal of Gastroenterology addresses this question. A research team led by Dr....

U.S. researchers, in studies involving mice, link a diarrhea-causing bacteria to a type of colon cancer. Study leader Dr. Cynthia Sears of The John Hopkins University School of Medicine says strains of this common bacteria -- Bacteroides fragilis -- sometimes trick immune system cells into allowing colon tissue to be continuously inflamed and may set the stage for malignancy. This could be the H. pylori of colon cancer, Sears says in a statement. H.pylori is a bacteria known to cause stomach...

Bug could be the 'H. pylori of colon cancer,' researchers say Johns Hopkins scientists say they have figured out how bacteria that cause diarrhea may also be the culprit in some colon cancers. The investigators say that strains of the common Bacteroides fragilis (ETBF) dupe immune system cells into permitting runaway colon tissue inflammation, a precursor for malignant growth. "This could be the H. pylori of colon cancer," says Johns Hopkins infectious disease specialist, Cynthia Sears, M.D.,...

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.The Proceedings of the National Academy of Sciences reports the...

Helicobacter pylori, nonsteroidal anti-inflammatory drug use and smoking are the most important risk factors for peptic ulcer. Alcohol intake may also play a role in the development of gastric ulcers. Psychological stress may also have an impact on the onset and course of ulcer disease. However, very little is known as to whether childhood adversities involving financial problems, conflicts in the family, problems with alcohol, and matters of personal security are associated with peptic...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...
