AUSTRALIA ANTIGEN (A HEPATITIS-ASSOCIATED ANTIGEN)

Australia Antigen (a Hepatitis-associated Antigen)

Australia antigen [Au(1)], a particle associated with viral hepatitis, was isolated from the plasma of a patient with chronic anicteric hepatitis and leukemia who had received radioactive phosphorus. We have found that the immunoreactivity and appearance of Au(1) in the electron microscope were not altered by treatment with enzymes including trypsin, pronase, lipase, phospholipase C, ribonuclea...

Proceedings: Hepatitis-associated-antigen-positive hepatitis in a tuberculosis unit.

An outbreak of hepatitis-associated-antigen-(HB Ag)-positive hepatitis in a hospital unit for the care of male patients with pulmonary tuberculosis is described. Sixty-four patients were studied of whom 37 were HB Ag positive. Hepatitis developed in at least 20 and was icteric in 11. The illness was mild, without fatality due to hepatitis and persistent jaundice did not occur. A carrier state d...

Hepatitis-associated antigen in patients with cancer.

The hepatitis-associated antigen (HAA) (Australian antigen) is either the infective agent of viral hepatitis or a virus-related protein(l). It is present in the blood during the incubation period and early clinical course of acute viral hepatitis in adults(l,2). The presence of the HAA in Krugman's long incubation hepatitis (MS-2) and its absence in childhood hepatitis, epidemic hepatitis, and ...
