title: [Attempt to cause hepatitis in duck hepatitis B virus carrier ducks by immunization with DHBV protein].
abstract: In order to investigate the hypothesis that viral hepatitis is a host immune response against viral protein presented on hepatocytes, we attempted to cause hepatitis in DHBV carrier ducks by immunization with DHBV protein. While ducks injected with Freund Complete Adjuvant (FCA) showed only weak hepatitis, those immunized with DHBV particle protein showed severe hepatitis. This same procedure could not cause significant inflammation in the liver of ducks without DHBV infection. The severity of hepatitis was well associated with the frequency of the immunization. However, the degree of hepatitis activity was different among same times immunized ducks. Occurrence of hepatitis assumed to have close association with host immune response against viral protein.
