SEATTLE, May 28 /PRNewswire/ -- The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive - and thrive - within the stomach's acid-drenched environment, but until now they have had no proof. For the first time, researchers at Fred Hutchinson Cancer Research Center have found that, at least...

Unlocking the keys to H. pylori's helical structure may lead to better antibiotic drugs for diseases from ulcers and stomach cancer to diarrhea and cholera The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive "“ and thrive "“ within the stomach's acid-drenched environment, but...

It's been implicated as the bacterium that causes ulcers and the majority of stomach cancers, but studies by researchers at Stanford University, UC Davis, and the University of Pittsburgh have found that Helicobacter pylori (H. pylori) also may play a protective role "“ against the worldwide killer, tuberculosis (TB). In an article appearing online Wednesday in PloS ONE, Jay Solnick, UC Davis professor of medicine and microbiology, and his co-authors report that H. pylori infection may...

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...

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...

U.S. medical researchers say they've discovered popular glutamine supplements show promise in the treatment of stomach ulcers. Since it's been known Helicobacter pylori bacteria are responsible for stomach ulcers, antibiotics have become the primary therapy for such conditions. But scientists say bacteria are growing increasingly resistant to antibiotics. In the new study led by scientists at Beth Israel Deaconess Medical Center in Boston and the Massachusetts Institute of Technology,...

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. Infection of the stomach with H. pylori induces a local immune response with infiltration of the mucosa by macrophages, neutrophils and lymphocytes. Although the innate and adaptive immune...

If you want to know how prehistoric people migrated, follow the "bugs" they carried with them. A consortium of scientists that included two from Baylor College of Medicine and the Michael E. DeBakey Veterans Affairs Medical Center in Houston did just that and in a report in the current issue of the journal Science, they described the two prehistoric migrations that populated the nations of the Pacific Ocean by looking at the travels of two different strains of a particularly nasty bacteria...

Bacteria that cause stomach ulcers and cancer could also be giving us bad breath, according to research published in the December issue of the Journal of Medical Microbiology. For the first time, scientists have found Helicobacter pylori living in the mouths of people who are not showing signs of stomach disease.The mouth is home to over 600 different species of bacteria, some of which can cause disease. Helicobacter pylori has recently been shown to cause stomach ulcers and is also...
