[The history of Helicobacter pylori]

Histological and ultrastructural studies of gastric mucosa with spiral bacteria had been published at the Royal Perth Hospital of Western Australia in 1979. The pathologist Warren correlated them with inflammation. In 1981, Marshall was training in internal medicine. Warren, Marshall and Goodwin started culture of bacteria, but spiral bacteria were not cultured. The 35th culture was left during the Easter holiday, and after 5 days 1-mm transparent colonies were seen on the plate. Since discovery Helicobacter pylori(H. pylori) have continued to fascinate and challenge doctors and scientists for 18 years to come. In 2000, triple therapy with PPI, Amoxicillin and clarithromycin was approved for treatment of peptic ulcer disease in Japan.
