Helicobacter pylori (H. pylori) is a type of bacteria. Researchers believe that H. pylori is responsible for the majority of peptic ulcers. H. pylori infection is common in the United States. About 20 percent of people under 40 years old and half of those over 60 years have it. Most infected people, however, do not develop ulcers. Why H. pylori does not cause ulcers in every infected person is not known. Most likely, infection depends on characteristics of the infected person, the type of H. pylori, and other factors yet to be discovered. Researchers are not certain how people contract H. pylori, but they think it may be through food or water. Researchers have found H. pylori in the saliva of some infected people, so the bacteria may also spread through mouth-to-mouth contact such as kissing.
Helicobacter pylori is one tough bug. It can survive in the human stomach, a zone with a pH somewhere between that of lemon juice and battery acid. Now researchers have discovered how an H. pylori toxin gets into cells, a feat that helps the bacterium live in one of the most inhospitable environments in the body
A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer's disease.
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.
Researchers from the UPM's School of Computing and another researcher from Holland’s Radboud University Nijmegen have published an article in the Decision Support Systems journal proposing a technique for improving decision making in medical environments.
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.
Cranberry juice, long dissed as a mere folk remedy for relieving urinary tract infections in women, is finally getting some respect.
Cancer -- popularly understood as a result of mutations or mistakes within the genetic code in cells -- is also caused by infections from viruses, bacteria and parasites.
The patient in the study was the first case of gastric carcinosarcoma obtained in this part of the world . The patient was admitted by Dr. Tomislav Randjelovic as surgeon and Dr. Branka Filipovic as gastroenterologist.
The formation of a cancer is proven to be a multi-stage, multi-mechanism process by animal and human studies.
The alarming truth is more than 14.5 million people suffer from ulcers worldwide due to factors such as stress and the use of non-steroidal anti-inflammatory drugs (NSAIDS).
Many of the most successful microbes are those that inhabit but do not kill their host. Cheaters lose. Tuberculosis settles into the lungs. Helicobacter pylori, the microbe causing ulcers, burrows into the stomach where it thrives on acids. And Salmonella typhi takes up residence in the gallbladder. All of these organisms can persist in our bodies for decades. What explains their success?
Helicobacter pylori has been extensively studied and proven to be the main cause of chronic gastritis and peptic ulcer in the HIV-negative population.
Red wine is known to have multiple health benefits. Researchers at the University of Missouri-Columbia have found that red wine may also protect humans from common food-borne diseases.
Scientists have identified and described stem cells specific to several tissues and organs of the body - key master cells that give rise to the specialized cell types characteristic of that organ.
Chronic fatigue syndrome, also known as ME (myalgic encephalitis), is linked to a stomach virus, suggests research published ahead of print in Journal of Clinical Pathology.
New cases of stomach cancer are set to plummet a further 25 per cent in the West over the next decade, indicates research published ahead of print in the journal Gut .
Giving mothers and children in developing countries twice the WHO recommended doses of vitamin A, as suggested by an international vitamin group, does not have a beneficial effect.
Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.
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.
Recent evidence suggests that therapy currently used to treat Helicobacter pylori (H. pylori) infection, a major cause of upper gastrointestinal disorders, is unsuccessful in around 25 percent of cases.
