(AP)—A marine biologist says an aging dolphin that was stranded in a polluted New York canal and died there was ill and might not have survived anywhere. http://phys.org/news278619782.html Biology Mon, 28 Jan 2013 18:23:07 EST news278619782 University of Oregon scientists have discovered how the bacterium Helicobacter pylori navigates through the acidic stomach, opening up new possibilities to inactivate its disease-causing ability without using current strategies that often fail or are discontinued because of side effects. http://phys.org/news258897008.html Chemistry Thu, 14 Jun 2012 12:50:24 EST news258897008 (PhysOrg.com) -- An Australian study has found that a bacterium that causes ulcers and cancers of the stomach appears to dramatically reduce the risk of one particular type of oesophageal cancer. http://phys.org/news191829614.html Medicine & Health Fri, 30 Apr 2010 07:00:38 EST news191829614 Helicobacter pylori, a bacterium found in about 50% of humans worldwide, can cause stomach ulcers and, in extreme cases, gastric cancer. In an article for F1000 Medicine Reports, Seiji Shiota and Yoshio Yamaoka discuss the possible eradication of H. pylori infections http://phys.org/news187608287.html Medicine & Health Fri, 12 Mar 2010 10:10:01 EST news187608287 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. http://phys.org/news173529566.html Chemistry Wed, 30 Sep 2009 11:40:05 EST news173529566 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. http://phys.org/news170254620.html Medicine & Health Sun, 23 Aug 2009 13:57:37 EST news170254620 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. http://phys.org/news169313255.html Chemistry Wed, 12 Aug 2009 17:00:05 EST news169313255 Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics. http://phys.org/news161614249.html Medicine & Health Fri, 15 May 2009 13:51:13 EST news161614249 Results of the first human clinical studies confirm that a new yogurt fights the bacteria that cause gastritis and stomach ulcers with what researchers describe as almost vaccine-like effects, scientists in Japan will report today at the 237th National Meeting of the American Chemical Society. http://phys.org/news156956005.html Medicine & Health Sun, 22 Mar 2009 15:54:01 EST news156956005 (PhysOrg.com) -- Helicobacter pylori can cause stomach ulcers and cancers. Over half of the world’s inhabitants carrys this bacterium, but different variants are present on different continents. Up to now, biologists have differentiated between five populations of these bacteria. Researchers at the Max Planck Institute for Infection Biology in Berlin and at the University of Cork in Ireland have now discovered a new population of Helicobacter pylori bacteria that attests to the shared origin of the earliest inhabitants of Australia and New Guinea.
