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.
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.
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 â€“ against the worldwide killer, tuberculosis (TB).
Research team uncovers how the bacterium that causes ulcers travels through the sticky gels of stomach mucus.
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.
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.
If you want to know how prehistoric people migrated, follow the "bugs" they carried with them.
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.
