Patent ID: 7390492

Claim:
A method for producing a passive immunity vaccine against Sarcocystis neurona in horses, comprising: (a) providing Sarcocystis neurona 16 kDa antigen and Sarcocystis neurona 30 kDa antigen, as determined by SDS polyacrylamide gel electrophoresis; (b) immunizing one or more mammals with the Sarcocystis neurona 16 kDa antigen and the Sarcocystis neurona 30 kDa antigen, in admixture with an adjuvant, to produce antibodies against the Sarcocystis neurona 16 kDa 4antigen and antibodies against the Sarcocystis neurona 30 kDa antigen; (c) removing serum from the one or more immunized mammals; (d) isolating from the serum from the one or more immunized mammals the antibodies against the Sarcocystis neurona 16 kDa antigen and the antibodies against the Sarcocystis neurona 30 kDa antigen; and (e) administering the antibodies to the 16 kDa antigen and antibodies to the 30 kDa antigen, isolated in step (d), together to horses as the passive immunity vaccine against Sarcocystis neurona.
