Abstract
As a complement to chemotherapy and other control approaches, the development of an effective vaccine is necessary to combat Schistosomiasis japonica that remains a serious public health problem in China. In the present study, mice were vaccinated with purified recombinant protein LHD-Sj23-GST (large hydrophilic domain of 23 kDa antigen of S. japonicum fused with Sj26GST) emulsified with Freund's adjuvant (FA), Montanide ISA 206 and Montanide ISA 70 M and challenged with cercariae, the protective efficacy induced by the recombinant protein was evaluated, and the LHD-Sj23-GST-specific IgG and its subtypes were determined. The result revealed that a significant worm burden reduction (58.8%, 26.3% and 54.3%; P<0.05) was obtained in mice vaccinated with LHD-Sj23-GST emulsified with three different adjuvants compared to those mice treated with respective adjuvant only. ELISA test suggested that the high-level production of LHD-Sj23-GST-specific IgG1, IgG2a and IgG3 antibodies may participate in protecting against schistosome infection.
