By using an amplification-created restriction site method, the precore TAG mutant of hepatitis B virus was detected in 6 (75%) of 8 acute fulminant hepatitis B patients, 7 (58%) of 12 acute self-limiting hepatitis B patients, 35 (81%) of 43 hepatitis B virus surface antigen carriers with fulminant hepatitis, and 42 (70%) of 60 hepatitis B virus surface antigen carriers with chronic hepatitis. T...
Blood donations in England and Wales are collected from healthy donors who do not acknowledge factors associated with an increased risk of bloodborne infections. All donations issued for transfusion since the early 1970s have been tested for hepatitis B surface antigen as a marker of transmissible hepatitis B virus. These measures have resulted in low rates of transmission by transfusion but ha...
Five nonoverlapping antigenic sites (sites I through V) of woodchuck hepatitis virus surface antigen were identified with competitive binding assays involving monoclonal antibodies. Site I contributed to cross-reactions among surface antigens of hepatitis B-like viruses infecting woodchucks, ground squirrels, and humans. At least three distinct sites (sites I, II, and III) are responsible for c...
The systematic screening of 253 children with transfusion-dependent homozygous beta-thalassaemia revealed a high incidence of hepatitis B virus markers. The highest frequencies of hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (anti-HBc) were found in the group of patients with the smallest number of transfusions, while the highest frequency of antibody to hepatiti...
