Establishment of chronic carrier state by experimental transmission of duck hepatitis B virus (DHBV)

Experimental transmission of hepatitis B virus by semen and saliva.

The ability of human semen and saliva to transmit hepatitis B virus (HBV) by parenteral and nonparenteral routes was studied. Semen, donated by a hepatitis B surface antigen (HBsAg)- and hepatitis B e antigen (HBeAg)-positive carrier, was administered to one gibbon by subcutaneous inoculation and to another by intravaginal instillation. Both developed HBsAg, followed by the development of antib...

The Study of Cerumen Hepatitis B Infection in Chronic Hepatitis B Patients by Real-Time PCR

Introduction: The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including se...

Sexual transmission of hepatitis B surface antigen. Infection of husbands by HBsAg carrier-state wives.

The husbands of 68 hepatitis B surface antigen (HBsAg) carrier-state wives were tested for the presence of hepatitis B surface antibody (HBsAb) and antigen (HBsAg) to assess possible transmission of HBsAg. Eight (11.8%) of the 68 husbands gave negative results for HBsAg and 22 (32.4%) positive results for HBsAb. Furthermore, eight (26.7%) of 30 husbands with presumed HBsAg transmission from the...
