Twenty-eight Japanese big ear rabbits were randomly divided into control group and experimental group. Twenty rabbits in experimental group were each infected with 3000 larvae of Trichinella spiralis. Serum and saliva samples were collected at pre-infection and every week after infection, and were examined for IgG antibody by indirect ELISA using T.
