title: Identification of new enzyme biotypes of Helicobacter pylori isolated in Japan.
abstract: The enzyme biotype of 86.5% of strains of Helicobacter pylori isolated in Japan could not be determined by the method used for the identification of the biotypes defined by Reina and Alomar (1989). A modified system for naming of biotypes is proposed.
