Viral nucleic acid synthesis and antigen accumulation in pancreas and kidney of Pekin ducks infected with duck hepatitis B virus.

Abstract

Liver, pancreas, and kidney from Pekin ducks infected with duck hepatitis B virus (DHBV) were assayed for the presence of both viral antigen and replication-specific forms of viral nucleic acid. In young congenitally infected ducks, antigen was detectable in hepatocytes and bile duct epithelia, in kidney glomeruli and tubular epithelia, and in cells localized to pancreatic acini. In older experimentally infected ducks, antigen was detectable in hepatocytes, in glomeruli and tubular epithelia, and in cells localized to presumptive pancreatic alpha-islets. All but the glomeruli-associated viral antigen appeared to be localized to the cytoplasm of antigen-positive cells. Much of the glomeruli-associated antigen appeared to be extracellular and was detected in glomeruli that were positive for the accumulation of immunoglobulin, observations suggestive of the deposition of viral antigen-antibody complexes. As analyzed with bulk tissue, replication-specific forms of viral nucleic acid were detectable in liver and pancreas from the young congenitally infected ducks and in liver and kidney from the older experimentally infected ducks.
