Two antigenic specificities in the Australia antigen.

Abstract

SummaryTwo antigenic specificities have been detected in Australia antigens identified in Melbourne. One specificity was common to all antigens studied, the other was observed in approximately 50% of patients with Au‐positive acute viral hepatitis and also in all of a group of antigen‐positive institutionalized Mongols.In patients with acute viral hepatitis the antigenic type detected remained constant, even if a carrier state developed.
