A technique for liver biopsy in Pekin ducks.
The duck hepatitis B virus (DHBV), a member of the hepadna-virus group, has become a useful animal model for exploring important aspects in this family of viruses such as viral replication, course of infection, and the response to antiviral therapy. In chronically DHBV infected ducks, repeated analyses of liver tissue are important in defining the degree of viral replication and liver injury. We describe a technique for repeated liver biopsy using a Keyes skin punch biopsy. This technique provided sufficient quantities of liver tissue for serial analyses with minimal hemorrhage in 18 Pekin ducks. This procedure offers a safe and reliable method of obtaining serial liver biopsies.
