Now you can run your own in-house quality control inspection without incurring any extra cost and at your own convenience. We have developed a new H. pylori test kit, called H. pylori plus. It comes with an, all inclusive, positive control system, which will allow the end user to run internal quality control tests without the need of external standards or studies.Our classic H. pylori IgA and IgG test kits continue to be available. However, now, besides our standard tests, you can also get the new H. pylori plus.The Helicobacter pylori colonize and infect the stomach mucosa. That causes gastritis type B and duodenal ulceration, sometimes gastric ulceration as well. Chronic atrophic gastritis leads sometimes to a gastric adenocarcinoma.Helicobacter pylori are spirally shaped, Gram-negative rods with lophotrichous flagellation (see fig.). The pathogenicity factors include pronounced motility for efficient target cell searching, adhesion to the surface epithelial cells of the stomach, urease that releases ammonia from urea to facilitate survival of the cells in a highly acidic environment and a cacuolizing cytotoxin (VacA) that destroys epithelial cells.
