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. Infection of the stomach with H. pylori induces a local immune response with infiltration of the mucosa by macrophages, neutrophils and lymphocytes. Although the innate and adaptive immune...

If you want to know how prehistoric people migrated, follow the "bugs" they carried with them. A consortium of scientists that included two from Baylor College of Medicine and the Michael E. DeBakey Veterans Affairs Medical Center in Houston did just that and in a report in the current issue of the journal Science, they described the two prehistoric migrations that populated the nations of the Pacific Ocean by looking at the travels of two different strains of a particularly nasty bacteria...

Bismuth compounds have been used for centuries in medicine. The discovery of H. pylori in 1983 led to renewed interest in bismuth compounds, because these were found to successfully treat the infection in combination with antibiotics. However, in the 1970s bismuth salts, used at high doses for prolonged periods, were found to lead to neurotoxicity. There has been no summary of evidence for the toxicity of bismuth when used for short periods as part of H. pylori eradication therapy. A research...

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. For the first time, scientists have found Helicobacter pylori living in the mouths of people who are not showing signs of stomach disease.The mouth is home to over 600 different species of bacteria, some of which can cause disease. Helicobacter pylori has recently been shown to cause stomach ulcers and is also...

U.S. medical scientists say they've determined chronic inflammation can cause stomach cancer -- the second leading cause of cancer deaths in the world. The multi-center research team led by Columbia University Medical Center said it discovered, for the first time, that elevated levels of a single pro-inflammatory cytokine, an immune system protein called IL-1 Beta, can start the progression towards stomach cancer. The scientists said they hope their finding will lead to development of ways...

By Sepulveda, Antonia R Patil, Madhavi Context.-Most types of gastritis can be diagnosed on hematoxylin- eosin stains. The most common type of chronic gastritis is Helicobacter pylori gastritis. Reactive or chemical gastropathy, which is often associated with nonsteroidal anti-inflammatory drug use or bile reflux, is common in most practices. The diagnosis of atrophic gastritis can be challenging if few biopsy samples are available and if the location of the biopsies in the stomach is not...

By Chaudhry, A S Kochhar, R; Kohli, K K Proton pump inhibitors (PPIs) are extensively metabolized in the liver by CYP2C19, that demonstrates genetic polymorphism with 21 mutant alleles. The subjects can be divided into 2 groups with respect to CYP2C19 phenotypes viz., extensive metabolizers (EMs) and poor metabolizers (PMs) of PPIs. This division results in marked interindividual variations in the pharmacokinetics and pharmacodynamics of PPIs in the population. Intragastric pH values and...

LAKEVILLE-MIDDLEBORO, Mass., Aug. 5 /PRNewswire/ -- New research suggests that cranberry juice can be as effective as probiotics in maintaining good digestive health. The double-blind trial at the University of Chile found a regular 6.8 oz. serving of 25% cranberry juice was as effective as the probiotic studied in suppressing growth of H. pylori among asymptomatic children. The study also showed the potential for an increased benefit when cranberry and probiotics are combined. "This...

U.S. Researchers reported on Tuesday that a type of bacteria only recently revealed as a major cause of ulcers and stomach cancer may help protect children from developing asthma. Helicobacter pylori, a bacterium that has co-existed with humans for at least 50,000 years, may lead to peptic ulcers and stomach cancer, but children between the ages of 3 and 13 who carried the bug were 59 percent less likely to have asthma than uninfected children, they reported. "Our findings suggest that...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...
