Latest Helicobacter pylori Stories

Researchers report that Helicobacter pylori, the only bacterium known to survive in the harsh environment of the human stomach, directly activates an enzyme in host cells that has been associated with several types of cancer, including gastric cancer. Chronic infection with H. pylori is a well-documented risk factor for several forms of gastric cancer, but researchers have not yet determined the mechanisms by which specific bacterial factors contribute to cancer development. Nearly one-half...

NEW YORK, Dec. 1 /PRNewswire/ -- Reportlinker.com announces that a new market research report is available in its catalogue: Peptic Ulcer Testing - A World Market Intelligence Report http://www.reportlinker.com/p0164350/Peptic-Ulcer-Testing---A-World-Market-Intelligence-Report.html The prevalence of peptic ulcers in developing, and underdeveloped countries is greater than in developed countries. The bacteria, helicobacter pylori (H. pylori), is found to be the main cause of peptic ulcer...

The gastric cardiac adenocarcinoma (GCA) is a very rare disease. In recent decades, however, the incidence of the GCA has increased dramatically in many Western countries. An increasing trend in GCA is also observed in municipal regions but not in rural regions of China. Another striking feature is the strong male predominance among patients with GCA. Some of the reasons above are still unclear and require further epidemiological investigations. A research article published on November 21,...

Research team uncovers how the bacterium that causes ulcers travels through the sticky gels of stomach mucus Mucus is more than gross--it's a critical barrier against disease, trapping many of the germs that want to invade your body. A wet mesh of proteins, antiseptic enzymes and salts, mucus is what keeps all but a few microbes from wreaking havoc on many of our most exposed tissues. Helicobacter pylori is one of the few. The tiny, corkscrew-shaped microbe bores through the mucus that lines...

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. Cyclooxgenase-2 (COX-2) is a prostaglandin-synthesizing enzyme. Elevated expression of COX-2 is observed in a wide variety of human malignancies, including gastric cancer. Long-term high dose COX-2 inhibitors can inhibit gastric carcinogenesis in animal models, but the possible...

Helicobater pylori, a bacteria implicated in peptic ulcers and gastritis, was eradicated in 95 percent patients who took a 7-day course of combination therapy with levofloxacin, omeprazole, nitazoxanide (Alinia®) and doxycycline (LOAD) compared to eradication in only 80.9 percent of patients on lansoprazole, amoxicillin and clarithromycin (LAC) for seven days. Results of a new study presented at the Annual Scientific Meeting of the American College of Gastroenterology reveal...

Helicobacter pylori (H pylori) is a gram negative bacterium which infects about 50% of the world population. H pylori colonization causes a strong systemic immune response. Various tools have been employed to identify the relationship between H pylori and gastric cancer, including c-DNA microarrays. However, most of these methods did not consider the systematic interaction of biological components. A research team from South Korea studied the complex reaction of gastric inflammation induced...

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...

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...
