Infection with the gastric bacterium Helicobacter pylori provides reliable protection against allergy-induced asthma, immunologists from the University of Zurich have demonstrated in an animal model together with allergy specialists from the University Medical Center of the Johannes Gutenberg University Mainz. Their results published in the prestigious Journal of Clinical Investigation confirm the hypothesis recently put forward that the dramatic increase in allergic diseases in industrial...

The stomach bacteria responsible for ulcers could also play a role in the development of Parkinson's disease according to research presented today at the 111th General Meeting of the American Society for Microbiology. "Infection of late middle-aged mice with a particular strain of the bacteria Helicobacter pylori results in development of Parkinson's disease symptoms after 3-5 months," says Traci Testerman of Louisiana State University Health Sciences Center, Shreveport, who presented the...

Administration of Helicobacter pylori DNA reduces symptoms, new research reveals pathway for future treatments ANN ARBOR, Mich., May 5, 2011 /PRNewswire-USNewswire/ -- DNA from Helicobacter pylori, a common stomach bacteria, minimizes the effects of colitis in mice, according to a new study by University of Michigan Medical School scientists. The study published in Gut this month was performed by a team of investigators assembled by senior author John Y. Kao, M.D. of the University of...

An international team of researchers led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have sequenced the genome of an Amerindian strain of the gastric bug Helicobacter pylori, confirming the out-of-Africa migration of this bacterial stowaway to the New World. Experiments in animals have highlighted how specific genes in the bacterial strain may be crucial to the onset of inflammation and disease. H. pylori is a bacterium that colonizes the stomachs of over...

The clinical outcome of gastric disease may involve differences in the prevalence or expression of bacterial virulence factors. Contrary to Asian studies, Western studies have disclosed associations between the presence of babA2 gene and gastric cancer. Evidence concerning BabA adhesin-associated genes is insufficient in Costa Rica, where the incidence of gastric cancer is very high, similar to Japan. The babA2 gene, which encodes BabA, may play a role in the development of gastric cancer in...

Helicobacter pylori (H. pylori) are considered to be the most important etiological agents of chronic gastritis. The eradication of H. pyloridepends on the combination of antibiotics and acid suppression drugs. Unfortunately, the side effects of antibiotics reduce the curative effect and treatment compliance. Probiotics provides an alternative method which can inhibit H. pylori infection efficiently without antibiotics associated side effects. A research team from China investigated the...

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...

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...

Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world's population, causing stomach ulcers and other diseases. They identified a group of substances that block a key chemical pathway that the bacteria need for survival. Their study, which could lead to new, more effective antibiotics to fight these hard-to-treat microbes, is scheduled for the October 16 issue of ACS Chemical Biology, a monthly...

Although it has been demonstrated that Helicobacter pylori causes gastric cancer, it is still controversial that whether H. pylori eradication therapy is effective in primary prevention of gastric cancer. This is especially important for Yamagata Prefecture, a region of Japan with the second highest incidence of gastric cancer in the world. A research article to be published on September 14, 2009 in the World Journal of Gastroenterology addresses this question. A research team led by Dr....
