Abstract

Tree shrews (Tupaia belangeri) are used as an animal model to test the inactivation of vaccines, the harmlessness of blood products and the effectiveness of chemotherapeutic agents and disinfectants against viral hepatitis. The antibody determinations are performed at specific intervals for a period of 150 days in the case of viral hepatitis type A and 60 days in the case of viral hepatitis type B.
