Objective To evaluate the immunogenicity and immunoprotective effect of heat shock protein 60 kDa(SjHSP60)of Schistosoma japonicum in mice after immunization and challenge infection,and explore the mechanism.Methods B cell/antibody-related databases and analysis tools were used to predict B-cell epitopes of SjHSP60.The mice were immunized with the recombinant SjHSP60 and challenged with S.japonicum cercariae.SjHSP60-specific antibodies in serum were detected by ELISA.The level of splenocyte proliferation wa...
