Human hepatitis B-like viruses have been found in several animal species, including Chinese ducks. Sera from Chinese carrier ducks which were positive for duck hepatitis B virus (DHBV) were inoculated in 33 Japanese one-day-old ducklings. The same sera were inoculated in four 3week-old ducklings, an

A 14-month old female Pekin duck experimentally infected as an embryo with duck hepatitis B virus via the amniotic route has been a chronic carrier of duck hepatitis B virus with very high (P/N) values of DNA polymerase activity since hatching. All the progeny were, on evaluation for congenital infe
Liver sections were stained with orcein, and duck hepatitis B virus was identified in sera and livers by the hybridization technique in 106 ducks (44 Chinese ducks, 15 Japanese ducks and 47 Japanese ducklings). Orcein-positive hepatocytes were found in 18 of 38 (47%) duck hepatitis B virus DNA serop
An attempt was made to infect primary duck hepatocyte cultures with duck hepatitis B virus in vitro in order to clarify the biology of hepatitis B virus. Livers of ducklings, 0 to 17 days posthatch, without viremia were digested ex situ by perfusion of collagenase solution through the portal or hepa
Hepatitis B virus DNA (HBV DNA) in serum was measured by a Spot hybridization technique in a consecutive series of 79 cases with chronic HBV infection from Taiwan. HBV DNA was found in 96.3% (52/54) of HBeAg-positive, 66% (2/3) with neither ABeAg or anti-HBe and in 63.6% (14/ 22) of anti-HBe positiv
## Abstract Liver and serum samples from 67 children with hepatitis B chronic infection, whether or not treated with recombinant interferon, were analyzed for the presence of hepatitis B virus DNA. After followβup, 44/67 (66%) still had serum and liver viral DNA; 23/67 (34%) were negative for serum
