There have been no studies addressing the detailed sequence of embryonic infection with duck hepatitis B virus (DHBV). Therefore, duck embryos from flocks infected with DHBV were examined to study the sequence of infection by DHBV in various embryonic tissues. Embryos from flocks infected with DHBV were harvested in duplicates from 7 to 25 days of incubation. Whole embryos (to 12 days) or dissected embryonic tissues were fixed, paraffin embedded, and stained for DHBV surface antigen (DHBsAg) using a peroxidase-antiperoxidase technique. Isolated hepatic cells were infected in 7-day-old embryos, and these increased in number until 11 days, when most cells were positive for DHBsAg. Endocrine pancreatic cells were positive from day 10, but only an occasional exocrine pancreatic cell was infected after day 20. Renal tubule cells were positive for DHBV by day 11, increasing in number until about day 18, after which a decline in numbers of infected cells occurred. Renal glomeruli became positive for DHBsAg from day 24. When present in the developing embryo, thymus, bursa of Fabricius, spleen, bone marrow, lung, and duodenum remained negative for DHBsAg. It was concluded that the timing of infection of specific tissues was not necessarily related to cellular maturity but may reflect a need for specific metabolic functions that permit viral replication.
