Latest Helicobacter pylori Stories
Experimental animal studies have shown that H. pylori shares several antigenic regions in common with acid secreting cells in gastric mucosa.
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.
NEW YORK, Dec.
The gastric cardiac adenocarcinoma (GCA) is a very rare disease.
Research team uncovers how the bacterium that causes ulcers travels through the sticky gels of stomach mucus.
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.
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 (AliniaÂ®) and doxycycline (LOAD) compared to eradication in only 80.9 percent of patients on lansoprazole, amoxicillin and clarithromycin (LAC) for seven days.
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.
A special protein in the lining of the stomach has been shown to be an important part of the bodyâ€™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.
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...
