[Duck hepatitis B virus (DHBV) and viral DNA in duck hepatocellular carcinoma and liver tissue].

Abstract

The hybridization test for duck hepatitis B virus DNA was performed in 34 ducks with hepatoma from Qidong, Jiangsu province. Among the 34 hepatoma ducks, 18 were positive for DHBV DNA in the serum and 27 were positive in the tumor and/or liver tissue. Tissue sections were stained with Victoria blue nuclear fast red for detecting DHBV surface antigen. Victoria blue positive cells were found in 11 tumors and 15 paratumorous regions of 23 ducks with hepatocellular carcinoma. Although paratumorous regions were positively stained in 3 of 8 ducks with cholangiocarcinoma, all were negative within their tumors. All paratumorous regions and 2 tumor regions of 3 ducks with hepatocellular-cholangiocarcinoma were positive for Victoria blue. The results suggest that duck hepatocellular carcinoma be closely related to DHBV infection.
