Hepatitis B virus DNA and e antigen in serum from blood donors in the United Kingdom positive for hepatitis B surface antigen.
نویسندگان
چکیده
Serum samples from 214 blood donors in the United Kingdom who were carriers of hepatitis B surface antigen (HBsAg) were examined for hepatitis B virus deoxyribonucleic acid (DNA) by DNA:DNA hybridisation and for hepatitis B e antigen (HBeAg) and its antibody. One fifth of the donors carried infectious virus in their circulation. The presence of hepatitis B virus DNA correlated well with that of HBeAg, although hepatitis B virus DNA was found in five serum samples that were negative for HBeAg. It is concluded that analysis of serum samples for hepatitis B virus DNA by hybridisation should be the method of choice for determining whether carriers of HBsAg are infectious.

Background and Aims: Occult hepatitis B virus infection (OBI) is known as an important source of hepatitis B virus (HBV) infection. It is categorized as Hepatitis B surface antigen (HBsAg) not being present and low DNA viral load in serum. In this study, an attempt was made to investigate the outbreak of anti-HBc and OBI among the HBsAg-negative donors in Golestan province. Materials and Metho...

DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
