Barry Marshall

Barry J. Marshall, MBBS (born 30 September 1951 in Kalgoorlie, Western Australia) is an Australian physician and Professor of Clinical Microbiology at the University of Western Australia. He is well-known for proving that the bacteria Helicobacter pylori is the cause of most stomach ulcers, reversing decades of medical doctrine which held that ulcers were caused by stress, spicy foods, and too much acid. Professor Marshall (Medicine and Pharmacology) completed his undergraduate medical degree at UWA in 1974. He met Robin ...

In 1875, German scientists found spiral bacteria in the lining of the human stomach; the bacteria could not be grown in culture and the results were eventually forgotten[2]. In 1892, the Italian researcher Giulio Bizzozero described spiral bacteria living in the acidic environment of the stomach of dogs. Professor Walery Jaworski of the Jagiellonian University in Kraków investigated sediments of gastric washings obtained from humans in 1899 ...

Gastric cancer and gastric MALT lymphoma (lymphoma of the mucosa-associated lymphoid tissue) have been associated with H. pylori, and the bacterium has been categorized as a group I carcinogen by the International Agency for Research on Cancer (IARC). While the association is reasonably strong, it is not entirely clear that there is a causal relationship involved. Two related mechanisms by which H. pylori could promote cancer are under investigation. One mechanism involves the enhanced production of free radicals near See also:

Several strains are known, and the genomes of two have been completely sequenced[11]. The genome of the strain "26695" consists of about 1.7 million base pairs, with some 1550 genes. The two sequenced strains show large genetic differences, with up to 6% of the nucleotides differing. Study of the H. pylori genome is centered on attempts to understand pathogenesis, the ability of this organism to cause disease. There are 62 genes in the " ...

Infection may be symptomatic or asymptomatic (without visible ill effects). It is estimated that up to 70% of infection is asymptomatic. The bacteria have been isolated from feces, saliva and dental plaque of infected patients, which suggests gastro-oral or fecal-oral as possible transmission routes. It is estimated that about 2/3 of the world population are infected by the bacterium. Actual infection rates vary from nation to nation - the West (Western Europe, North America, Australasia) having rates around 25% and the Third W ...

H. pylori is a spiral-shaped gram-negative bacterium, about 3 micrometres long with a diameter of about 0.5 micrometre. It has 4-6 flagella. It is microaerophilic, i.e. it requires oxygen but at lower levels than those contained in the atmosphere. It uses hydrogen methanogenesis as an energy source. It tests positive for oxidase and catalase. With its flagella and its spiral shape, the bacterium drills into the mucus layer of the stomach, and then can either be found suspended in the gastric mucosa or attached to epithelial cel ...

In patients who are asymptomatic, treatment is not usually recommended. In gastric ulcer patients where H. pylori is detected, normal procedure is eradication to allow the ulcer to heal. The standard first-line therapy is a one week triple-therapy of amoxicillin, clarithromycin and omeprazole – though sometimes a different proton pump inhibitor is substituted, or metronidazole is used in place of amoxicillin in those allergic to penicillin. Such a therapy has revolutionised the treatment of gastric ulcers and has made ...
