Mice with different naturally occurring stomach bacteria have distinct susceptibilities to disease caused by Helicobacter pylori, the well-known cause of ulcers in humans, according to a study published online ahead of print in the journal Infection and Immunity. This is the first study to document (in mice) that the presence of certain bacteria in the stomach microbiota can prevent pathology from H. pylori. http://medicalxpress.com/news/2013-03-stomach-microbiota-modulate-resistance-pylori-driven.html Immunology Mon, 25 Mar 2013 12:34:40 EST news283433672 Half of the world's human population is infected with the stomach bacteria called Helicobacter pylori, yet it causes disease in only about 10 percent of those infected. Other bacteria living in the stomach may be a key factor in whether or not H. pylori causes disease, according to a new study led by scientists at the University of California, Santa Cruz. http://medicalxpress.com/news/2013-03-bacteria-disease-stomach-infection.html Immunology Tue, 12 Mar 2013 13:17:47 EST news282313058 In an analysis of the results of interventions to eradicate the bacterium Helicobacter pylori (a risk factor for gastric cancer) in seven diverse community populations in Latin America, researchers found that geographic site, demographic factors, adherence to initial therapy and infection recurrence may be as important as the choice of antibiotic regimen in H pylori eradication interventions, according to a study appearing in the February 13 issue of JAMA. http://medicalxpress.com/news/2013-02-factors-eradication-bacteria-linked-gastric.html Cancer Tue, 12 Feb 2013 16:30:02 EST news279906669 A new study by NYU School of Medicine researchers reveals that an especially virulent strain of the gut bacterium Helicobacter pylori (H. pylori) isn't implicated in the overall death rate of the U.S. population, and may even protect against stroke and some cancers. The findings, based a nationwide health survey of nearly 10,000 individuals over a period of some 12 years, are published online, January 9, in the journal Gut. http://medicalxpress.com/news/2013-01-bacterium.html Diseases, Conditions, Syndromes Wed, 09 Jan 2013 00:00:02 EST news276883496 (Medical Xpress)—Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to the growth of certain bacteria. Scientists hope to be able to treat such conditions as stomach ulcers, TB and MRSA. http://medicalxpress.com/news/2012-12-antibiotics-based-principle-defeat-mrsa.html Medical research Tue, 18 Dec 2012 10:21:09 EST news275048442 People with AIDS are at increased risk for developing esophageal and stomach carcinoma as well as non-Hodgkin lymphomas (NHLs), according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. http://medicalxpress.com/news/2012-09-aids-patients-esophageal-stomach-cancers.html Cancer Mon, 24 Sep 2012 13:02:01 EST news267710511 Stomach cancer doesn't get the same publicity as lung or breast cancer, but it is a health threat to be taken very seriously. "Gastric cancer is the second leading cause of worldwide cancer mortality, with an annual death rate of over 700,000 individuals," explains Patrick Tan of the A*STAR Genome Institute of Singapore. He notes that this disease is especially prevalent in Asia; gastric cancer is the fifth most common cancer amongst Singaporean men. http://medicalxpress.com/news/2012-09-bonanza-genomic-sequence-valuable-insights.html Genetics Wed, 12 Sep 2012 08:45:51 EST news266658344 One of the biggest risk factors for liver, colon or stomach cancer is chronic inflammation of those organs, often caused by viral or bacterial infections.

Molecular biologists from the University of Zurich have now identified a mechanism of Helicobacter pylori that damages the DNA of cells in the gastric mucosa and sets them up for malignant transformation. http://medicalxpress.com/news/2011-09-stomach-bacterium-human-dna.html Diseases, Conditions, Syndromes Tue, 06 Sep 2011 13:27:52 EST news234534453 If you were the size of a bacterium, the lining of a stomach would seem like a rugged, hilly landscape filled with acid-spewing geysers, said Manuel Amieva, MD, PhD, assistant professor of pediatrics and of microbiology and immunology. Stomach-dwelling bacteria called Helicobacter pylori, the cause of ulcers and some gastric cancers, must navigate through the treacherous terrain to find sanctuary in the mucous layer that coats the inside of the stomach. http://medicalxpress.com/news/2011-08-idea-disable-bug-ulcers-cancer.html Cancer Mon, 08 Aug 2011 11:00:02 EST news232017822 Helicobacter pylori, the bacterium known to cause peptic ulcers, is also the primary cause of gastric cancer, which is a leading cancer killer globally. http://medicalxpress.com/news/2011-07-standard-drug-pylori-therapy-regimens.html Medications Wed, 20 Jul 2011 03:57:07 EST news230353013 Infection with the gastric bacterium Helicobacter pylori provides reliable protection against allergy-induced asthma, immunologists from the University of Zurich have demonstrated in an animal model together with allergy specialists from the University Medical Center of the Johannes Gutenberg University Mainz.
