Protection induced by vaccinating sheep with a thiol-binding extract of Haemonchus contortus membranes is associated with its protease components.

abstract：:Immunity to Schistosoma mansoni in the mouse was induced by vaccination with adult worm surface membrane (mb-S). Of several adjuvants tested, including Freund's, BCG and alum, 50 micrograms of saponin per mouse given subcutaneously with the antigen was the easiest to administer, and gave consistent protection, approac...
