Background: To serially observe the pathologic changes in livers of tree shrews and macaca assamensises infected with HHBV.

Methods: 10 adult tree shrews and 28 macaca assamensises were inoculated with HBV rich human sera. The liver of the animals were regularly biopsied. The liver samples were examined histopathologically by HE staining. Some samples were stained for HBsAg by immunohistochemistry (IH), and HBV DNA by in situ hybridization (ISH).

Results: HBsAg in 80% of tree shrews infected with HHBV can be detected by IH, HBV DNA in 50% of those can be found by ISH.The positive rates of HBsAg in macaca assamensises' livers were 25% by IH, none HBV DNA was detected.

Conclusion: The tree shrew model seems to be applicable for the research of human hepatitis B.
