Max Planck scientists succeed with a novel technique in the fight against the cause of peptic ulcer disease and gastric cancer.
Helicobacter pylori (H. pylori) is the causal agent of chronic gastritis, ulcer and gastric cancer.
Gastric cancer, one of the most common types of cancer, is associated with high mortality rates.
The clinical outcome of gastric disease may involve differences in the prevalence or expression of bacterial virulence factors.
Despite a strong response from our immune defense, the body is unable to rid itself of the bacterium Helicobacter pylori.
MODI'IN, Israel, Jan. 21 /PRNewswire/ -- Exalenz Bioscience has finalized production of the BreathIDÂ® and is preparing to ship the first devices and kits that are used in the detection of Helicobacter pylori bacteria.
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 â€“ against the worldwide killer, tuberculosis (TB).
A bacterial species that depends on cooperation to survive is discriminating when it comes to the company it keeps.
Researchers report that Helicobacter pylori, the only bacterium known to survive in the harsh environment of the human stomach, directly activates an enzyme in host cells that has been associated with several types of cancer, including gastric cancer.
Researchers have characterized a new multi drug resistant strain of Salmonella Typhimurium that is causing life-threatening disease in Africa.
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...
