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 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.
Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.
For those who suffer from stomach ulcers, the daily routine of breakfast, lunch and dinner can be painful. A common cause of these ulcers, as well as other gastric malignancies, is a bacterium called Helicobacter pylori .
Aspirin has long been hailed as one of the most effective, low-cost ways to help guard against a heart attack or stroke. However, international medical researchers caution that low doses of aspirin also increase a patient's chance of developing an ulcer, often without warning signs.
While searching for new targets for malaria drugs and vaccines, a team including a Howard Hughes Medical Institute (HHMI) medical student fellow reached a fundamental insight about evolution: different species make use of similar sets of proteins in different ways.
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.
Researchers have uncovered how members of one family of antibiotics kill bacteria that make people sick.
A new study has found that the most common form of oral cancer, is linked to three different types of mouth bacteria.
A common stomach bug may also be linked to the development of irregular heart rhythm, also known as atrial fibrillation, suggests a small study in Heart
Some diseases like ulcers and certain types of cancer, once thought to be primarily related to lifestyle factors, are now known to be caused by microorganisms, and many more syndromes, including some psychiatric conditions, may have a connection to infection, according to a report released today by the American Academy of Microbiology.
When it comes to gastric cancer, too little stomach acid can be just as dangerous as too much, according to scientists at the University of Michigan Medical School. Both extremes create inflammatory changes in the stomach lining and a condition called chronic atrophic gastritis, which over time often leads to cancer.
A number of clinical symptoms and signs are included under the broad group Rosacea. Facial flushing, the appearance of broken blood vessels and persistent redness of the face, eruption of inflamed spots & pimples, on the face and thickening of the sebaceous glands of the nose, with swelling & congestion in that area.
