A Novel Method for the Isolation of Helicobacter pylori from Highly Contaminated Specimens Helicobacter pylori is an established cause of chronic gastritis, duodenal and gastric ulcer, and is linked to gastric cancer. H. pylori is difficult to culture from extra-gastric and environmental samples due to heavy contamination with other microorganisms that inhibit the growth of H. pylori on commercially available media. These new sample treatment methods eliminate all other microorganisms while not affecting H. pylori, allowing diagnostic and environmental samples to be grown on non-selective growth media. Inventors: Qunsheng Song, Gerald W Zirnstein, and Benjamin D Gold CDC Reference Number: I-030-99/0 USPTO Serial Number: PCT/US01/40756 Patent Number: | |||||||||||||||||
