Relationship between serum cytokines profiles and hepatic fibrosis in schistosomiasis mansoni: an experimental study.

Forty of eighty mice (10 each group) were infected with S. mansoni cercariae and sacrificed at 3 weeks (G-A), 6 weeks (G-B), 12 weeks (G-C) and 16 weeks (G-D) post infection (P.I).

Evaluation of protective immunity of 28KD-GST as a vaccine against experimental Schistosoma mansoni.

Schistosoma mansoni GST was purified from adult worm homogenates by affinity chromatography. SDS-PAGE analysis of the purified antigen revealed that SmGST has molecular weight around 28 KD was used as a vaccine in a dose of 25 and 35 microg. Eleven groups of BALB/c mice of 10 mice each were vaccinated by GST.
