Two genome-wide association studies and a subsequent meta-analysis have found that certain genetic variations are associated with susceptibility to Helicobacter pylori, a bacteria that is a major cause of gastritis and stomach ulcers and is linked to stomach cancer, findings that may help explain some of the observed variation in individual risk for H pylori infection, according to a study in the May 8 issue of JAMA. "[H pylori] is the major cause of gastritis (80 percent) and...

Numerous epidemiologic studies have shown that a diet high in salt is associated with an increased risk of gastric cancer. Now Timothy L. Cover and colleagues of Vanderbilt University show that high dietary salt combined with infection by the ulcer-causing bacterium Helicobacter pylori greatly increases the risk of cancer. The study was published ahead of print in the journal Infection and Immunity. In the study, the researchers infected Mongolian gerbils with H. pylori. One set of gerbils...

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology, on Tuesday, March 12. In nature, the bacterium Geobacter sulfurreducens uses these nanowires, called pili, to transport electrons to remote iron particles or other microbes, but the benefits of these wires can also be harnessed by humans for use in fuel cells or...

April Flowers for redOrbit.com - Your Universe Online A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over. The findings of this study were published in a recent issue of Nature. On one side of the battle lines stands SAR11, a bacterium that´s the most abundant organism in the oceans, surviving where most other cells...

In an analysis of the results of interventions to eradicate the bacterium Helicobacter pylori (a risk factor for gastric cancer) in seven diverse community populations in Latin America, researchers found that geographic site, demographic factors, adherence to initial therapy and infection recurrence may be as important as the choice of antibiotic regimen in H pylori eradication interventions, according to a study appearing in the February 13 issue of JAMA. "Gastric adenocarcinoma is the...

Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...

Neisseria meningitidis is a heterotrophic gram-negative diplococcal bacterium best known for its role in meningitis and other forms of meningococcal disease such as meningococcemia. It is a major cause of morbidity and mortality during childhood in industrialized countries and is responsible for epidemics in Africa and in Asia. In the US there are approximately 2500 to 3500 cases of N. meningitides infections. Children under 5 are at a higher risk as well as people in the sub-Saharan...

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...

Haemophilus influenzae is a Gram-negative, rod-shaped bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. It is generally aerobic but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933 when the flu virology became apparent. It was the first free-living organism to have its entire genome sequenced. The project was completed and published in 1995. Two major categories were defined: the...

Haemophilus ducreyi is a fastidious gram-negative coccobacillus causing the sexually transmitted disease chancroid, a major cause of genital ulceration in developing countries characterized by painful sores on the genitalia. Early symptoms are dark and light green shears in excrement. Chancroid starts as an erythematous popular lesion that breaks down into a painful bleeding ulcer. It can be cultured on chocolate agar. It is an opportunistic microorganism that infects through the...
