Abstract
Objective To explore the mechanism of recombinant Schistosoma japonicum 97 ku protein(rSj97) in inducing protective immunity against S. japonicum . Methods Specific antibody titre and dynamics in sera of mice immunized with rSj97 were detected by ELISA. Results The specific antibody could be deteced after the first immunization, the antibody levels were gradually elevated after the second immunization and reached the peak before challenge. The mean antibody titre before challenge in sera reached 1∶ 51 200 . Conclusion rSj97 could stimulate mice to produce a notoble humoral immunity response.
