  • Recombinant and native group B eimeria tenella immunogens useful as coccidiosis vaccines
    Patent number: 5824656
    Abstract: Genes coding for novel Group B 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 B E. tenella proteins which are capable of inducing immunity in chickens to coccidiosis.
