Liver Orcein Stain and Viral DNA in Duck Hepatitis B Virus Infection in Chinese Ducks and Experimentally Infected Japanese Ducklings
Junko Mori, Masao Omata, Osamu Yokosuka, Fumio Imazeki, Yoshimi Ito, Katsuo Uchiumi, Yasuhisa Matsuyama, Ye Weifa, Kunio Okuda – 1 November 1984 – 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 seropositive ducks, and only in 3 of 68 (4%) seronegative ducks. The three ducks were all from a heavily infected flock in southern China.
