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.
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.
The occurrence of the disease is currently thought to be due to several factors including the toxic nature of the infecting strain, the genetic susceptibility of the host, and environmental factors.
Researchers have found that a bacteria found in the stomach, that can cause cancer and peptic ulcers, may have a role in protecting children from asthma.
The stomach bacterium Helicobacter pylori, which causes stomach cancer and peptic ulcers, may not be all bad.
The bacteria Helicobacter pylori substantially increase the risk of cancer in the lower stomach, but it may decrease the risk of cancer near the junction between the esophagus and the stomach, according to a study in the October 19 Journal of the National Cancer Institute.
Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria.
According to a new report fewer Americans are dying of cancer even though the rates of new cancers remains the same.
The U.S. Food & Drug Administration (FDA) is warning consumers and health care providers not to use a product called "bismacine," also known as chromocine.
One study, a meta-analysis of 59 trials, found little evidence that diet is associated with survival or prognosis.
For those who suffer from stomach ulcers, the daily routine of breakfast, lunch and dinner can be painful.
