Helicobacter pylori can multiply in autophagic vesicles
Helicobacter pylori, a Gram-negative, flagellated, microaerophilic bacterium, can selectively colonize in the human stomach. Its infection is widespread throughout the world, and is present in about 50% of the global human population with 80% in developing countries and 20-50% in industrialized countries. view more (2009-01-28)
Which is more accurate, serology test or C14-urea breath test?
Serology and C14-UBT are the most commonly used non-invasive tests of H. pylori infection. The diagnostic characteristics of the tests depend also on the prevalence of H. pylori infection in the population tested. view more (2008-09-10)
Bacteria increase risk of lower stomach cancer, decreases risk of upper
The bacteria Helicobacter pylori substantially increase the risk of cancer in the lower stomach, but it may decrease the risk of cancer near the junction between the esophagus and the stomach. view more (2006-10-18)
A new explanation of 'Asian paradox'
Although Helicobacter pylori (H. pylori) has been classified as a class I (or definite) carcinogen by World Health Organization (WHO), the controversy as to why only a minority of infected patients develop gastric cancer still remains. view more (2009-10-29)
H Pylori Eradication Reduces Risk Of Peptic Ulcers For Patients Taking Non-steroidal Anti-inflammatory Drugs
Screening and treatment for infection caused by the gastrointestinal bacterium Helicobacter pylori could substantially reduce the risk of ulcers for patients starting long-term non-steroidal anti-inflammatory drug (NSAID) treatment, conclude authors of a study in this week's issue of THE LANCET. A meta-analysis also published in this week's issue... view more... (2002-01-02)
Going from ulcers to cancer
Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others; it turns out these bacteria can exploit the surrounding stomach cells to protect them from the immune system. view more (2008-08-25)
Antibiotics may not be enough to stop recurrent gastric lymphoma caused by Helicobacter pylori
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind. view more (2005-08-25)
Why are tribal populations free from clinical symptoms infection with H pylori strains?
Helicobacter pylori is of growing concern today because of its crucial role in the pathogenesis of chronic gastritis, peptic ulcer diseases and in the multi-step carcinogenic process of gastric cancer. However, it is still an enigma why few strains are associated with ulcer formation with relevant clinical symptoms while others are not associated... view more... (2009-03-09)
H. Pylori bacteria may help prevent some esophageal cancers
Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature. These bacteria, which are called Helicobacter pylori, live in the stomachs of humans. view more (2008-10-06)
Why does aspirin increase the susceptibility of Helicobacter pylori to antimicrobials?
Resent studies reported that aspirin inhibited the growth of H. pylori in a dose-dependent manner and significantly affected the activity of virulence factors of H. pylori. view more (2009-03-03)
Hybrigenics completes First Protein Interaction Map of Bacterial Pathogen in Nature
Free Licence to Access this Protein Interaction Map Available to Academic Researchers on the Web Paris, France Hybrigenics, the functional proteomics company, announced today the completion of the first protein interaction map of a human bacterial pathogen: Helicobacter pylori. This large-scale protein interaction was generated by HYBRIGENICS,... view more... (2001-01-10)
Simple breath test may replace endoscopy
A simple breath test for detecting H pylori infection is as effective and safe as endoscopy and is less uncomfortable and distressing for the patient, conclude researchers in this week’s BMJ. view more (2002-04-24)
Prehistoric origins of stomach ulcers uncovered
An international team of scientists has discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. view more (2007-02-08)
Researchers describe how chronic inflammation can lead to stomach cancer
A multi-center research team, led by Columbia University Medical Center, has uncovered a major contributor to the cause of stomach cancer - the second leading cause of cancer-related mortality in the world. view more (2008-11-06)
Salt increases ulcer-bug virulence
Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease. view more (2007-05-23)
Tummy Bug Puzzle Unravelled
The bacterium, Helicobacter pylori, which infects the stomach, causes duodenal ulcer disease and is thought to cause stomach cancer. The question of why the bacteria are only found in the stomach has puzzled scientists for many years. Researchers at the Conway Institute and the Children's Research Centre at Our Lady's Hospital for Sick Children,... view more... (2004-05-11)
Is short-term Celecoxib intervention a effective method for preventing gastric carcinogenesis?
Since the isolation and culture of Helicobacter pylori (H. pylori) in 1983, this bacterium has become accepted as an important human pathogen for the development of gastritis, peptic ulcer, and gastric cancer. view more (2009-10-29)
Bacterial 'battle for survival' leads to new antibiotic
MIT biologists have provoked soil-dwelling bacteria into producing a new type of antibiotic by pitting them against another strain of bacteria in a battle for survival. view more (2008-02-27)
H Pylori tests not always useful for diagnosing ulcers
Routine testing for H pylori infection in patients consulting their general practitioner with indigestion (dyspepsia) does not aid the diagnosis of peptic ulcers, concludes a study from the Netherlands in this week's BMJ. Testing is useful only in patients at high risk of peptic ulcer disease, and these patients can be identified by asking three... view more... (2001-07-11)
Early treatment of stomach infection may prevent cancer
Based on research using a new mouse model of gastritis and stomach cancer, researchers from the Massachusetts Institute of Technology (MIT) say that prompt treatment of Helicobacter pylori (H. pylori) infections reverses damage to the lining of the stomach that can lead to cancer. view more (2008-05-01)
