Abstract
WE have reported unusually high DNA polymerase activity in sera obtained from chimpanzees infected with the hepatitis B virus1, and Kaplan et al.2 reported hepatitis B-specific DNA polymerase activity in sera of human patients during post-transfusion hepatitis. We and others3–5 also found DNA polymerase activities associated with Dane particles, the putative hepatitis B virus, or their naked core components. Reports6,7 of the specific association of an e antigen-e antibody system with carriage of HBsAg prompted us to examine HBsAg positive sera containing unusually high levels of DNA polymerase activity for the presence of e antigen or e antibody. Subsequently, we studied the effects of sera containing e antibody on high DNA polymerase activity in sera from individuals with acute hepatitis B, chronic asymptomatic hepatitis B, chronic aggressive hepatitis B or chronic non-B hepatitis.
