Recombinant eimeria tenella vaccines.

摘要

Genes coding for novel Group A, C, F, and H Eimeria tenella protein immunogens have been isolated and inserted into a novel expression vector which in turn has been used to transform appropriate hosts. The transformed host cells produce recombinant Group E. tenella proteins which are capable of inducing immunity in chickens to coccidiosis. Antibody prepared against the recombinant protein immunogens is used to isolate and identify the native protein from disrupted E. tenella sporulated oocysts.
